Epoxy resin is made through curing, or using heat, air, or chemicals to harden the substance. Often, people say “resin” without specifying which resin. Epoxy resin makes a strong and durable tabletop. Epoxy is an organic compound. With a limited pot life and risk of humidity issues, your staff needs to work quick and smart for good results. Epoxy and Polyurethane coatings exemplify superior long term qualities such as chemical and acid resistance, ease of maintenance, and aesthetic appeal. Epoxy resin counter tops are made from a mixture of materials then cured as a solid continuous product. With 98% solids, polyurea is 4x stronger and yet 98% more flexible than epoxy. Build/Thickness: Epoxy build coats are typically installed at 8 to 15 mils per application. Sean enjoys working closely with PIP’s sales and management group to develop and market new flooring products and systems to address end-user’s unique requirements. Both urethane and epoxy are used in many industrial products, including curing agents, paints, adhesive agents, foam and resins. I’ve been researching products on your website. Polyester and polyurethane resins are the most commonly used casting material available. Overview and Key Difference Epoxy resin dries, or cures, to a very hard, unexpansive surface and is only suitable for indoor use.
Like epoxy, polyurethane also comes in different formulations. Epoxy vs Resin • Epoxy is the name of an ingredient as well as the end product of epoxy resin manufacturing. If an uncured PU floor is attacked by water or condensation you may get this catastrophic results (like in the picture below). Epoxies are a type of polyurethanes. Polyurethane Resin vs Polyesther Resin. “What’s the difference with epoxy vs polyurethane coatings?” In the industrial floor coating world, while epoxies and polyurethanes are both thermosetting polymers, their differences in function and performance are vast. Epoxy resins can react with each other via catalytic homopolymerization and form cross-links between them. These range from flexible epoxies, to chemical-resistant epoxies, to fast-setting epoxies, etc. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols. Epoxy resin makes a strong and durable tabletop. It’s not as strong as epoxy but there are some occasions when it might do a better job. Johnson, Todd. Though they exhibit much thinner cured-film thickness, polyurethanes offer a number of unique advantages over epoxies. These epoxies are designed by having the curing agent with a small amount of epoxy resin. In very simple terms, a typical two-part epoxy coating contains a resin side and a hardener side. A polymer is a macromolecule that contains a large number of small repeating units (monomers). An old EPS blank can be broken down and recycled into a new blank. Aside from the elastic durability factor which makes polyurethane the number one choice by default, the resin is also more scratch-resistant, crack-resistant, temperature resistant and chemical resistant than epoxy. We also have crack and spall epoxy-based products that are USDA approved for meat and poultry plant-based applications. Epoxy’s quality of being an excellent insulator makes it possible to be used in the electrical industry. Epoxy resins less flexible and less abrasion resistant. Poly Surboard. Available here Polyurethane is a polymer material that has urethane linkages (carbamate linkages). However, there are some plant-derived sources as well. Finishes: Polyurethane finishes can range from satin to semi-gloss to high-gloss. it creates a perfectly serviceable bond and one which is likely to be clear in appearance as well as strong. 1. What is Epoxy? Because casting resins are typically capable of thicker pours, they dissipate heat (exotherm) much slower than coating epoxy. As a varnish style coating. As described above, epoxy is lighter, stronger, and more environmentally friendly.

Dans notre documentaire sur le sol de résine, abordons ici les avantages et inconvénients d’une résine époxy. When used as a topcoat over epoxy, they protect the underlying epoxy from yellowing over time. 5. Is Floor Cleaning and Maintenance Part of Your Safety Program? Cons • There are, some particular usage method of epoxy resin, it can be highly dangerous if not used correctly. An epoxy laminate will need less resin and less material, for the same strength and stiffness joint than polyester, so you save in goo and materials, offsetting to a degree the price difference for the resin. Why is Planet Earth Your True Friend for ESD Grounding? Epoxy and polyurethane are booth chemical resins with different reaction profiles and physical properties. If you’re contemplating some major build or repair projects involving fiberglass this summer, then you are probably trying to decide whether it is worth the added expense of using epoxy instead of polyester resin. Polyurethane injections can take anywhere between 15 to 45 minutes to cure, whereas epoxy options need 3 to 4 hours to fully cure at room temperature. You will notice that adhesives used for the production of cars, snowboards, bicycles, and many such things are epoxy resin or contains Epoxy in it. Here’s a quick breakdown on the differences between epoxy resin and polyester resin. Compare the Difference Between Similar Terms. The key difference between epoxy and polyurethane is that the epoxy contains epoxide groups whereas polyurethanes contain urethane linkages. This makes polyurethane coatings more resistant to scratches and similar damage and is why you’ll often find urethane resin floors in heavy traffic areas – such as multi-storey car parks. Installation & Performance: Upon curing, the epoxy build coat(s) provide a hard, durable surface with good impact resistance. They cannot be used as a complete system in itself. These epoxies are designed by having the curing agent with a small amount of epoxy resin. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } }
It is formed when isocyanates react with water or polyetheramines to create a urea linkage. For example, parts made for bumpers, spoilers, and fenders.
“It’s bare concrete and we need it to be durable, bright, safe and easy to clean. 2. Polyurethane coatings are only about 2 or 3 mils thick and just about 60% or 70% solids, depending on the manufacturing company you get the coating from. • Resins are used more in construction where there is no hurry for the final product. Show comparatively low resistance towards organic acids, Shows high resistance towards corrosion, inorganic acids, alkali solvents, organic alkalis and many other solvents. 2. Polyurethane: Expensive But Durable Finishing Products (300) Polyurethane delivers a tough and flexible coating to wood. Epoxy injection is performed through surface mounted ports. Although it sets up much faster, it has … The epoxy resin is less toxic to the board builder and the environment. Optional wear and safety additives can be incorporated into the topcoat texture. The epoxy/cloth laminate is comparable to using polyester resin with 3/4 oz. 4. 2018. However, epoxy resins will begin to gel in as quick as 20 minutes, whereas casting resins may take upwards of 18 hours to gel. In the application point of view, the main difference between epoxy and polyurethane is that the epoxy resins can resist moderate temperatures while the polyurethanes can withstand high temperatures. • Epoxy resin forms stronger bonds when it comes to gluing two pieces together and has better adhesive properties with surfaces like wood, metal or concrete. Like epoxy, it is a 2-part component that mixes resin with a catalyst to cause the curing reaction that makes the material hard. Polyurethane vs Rubber. The downsides of choosing polyurethane are: You need to brush big jobs. Epoxy is the most popular resin type used in flooring systems. • Epoxy resin forms stronger bonds when it comes to gluing two pieces together and has better adhesive properties with surfaces like wood, metal or concrete. Cure time for PU is much longer than PMMA. In the industrial floor coating world, while epoxies and polyurethanes are both thermosetting polymers, their differences in function and performance are vast. What is Polyurethane Polyurethanes "dry" in a fairly short time, but resins "cure" instead of drying and that takes at least 24 hrs. This gives them the desired properties. Epoxy Technology. • Epoxy is stronger than resin. A lighter board is easier to carry, easier to paddle, and will often feel faster when riding them along the face of the wave. In general, epoxy resins offer limited resistance to the organic acids that are found in large quantity of food and drink produce, whereas polyurethane systems boast unrivalled resistance to corrosion, inorganic, alkalis, organic alkalis and solvents. They are both light reflective, easy to clean, and long lasting. Epoxy vs polyurethane is a common topic brought up during my conversations. Polyurethane is generally more resistant to scratching, chemicals, UV rays, and general wear and tear than epoxy. PU casting resins can, just like epoxy resin and polyester resin, be combined with various additives as well as filling materials or colorants. Resin and epoxy are both adhesives commonly employed in the construction industry. In fact, in many cases, if the epoxy primer and build coats are well-bonded, a simple re-coat of the polyurethane topcoat may be all that is required every few years, depending upon use. In this guide, we’ll compare epoxy resin and polyurethane resin: keep reading to learn more. Epoxy is an organic compound. They also harden differently. Novolac epoxy resins for high temperatures. There are some differences between polyurethane and epoxy. Urethane is composed of organic, or carbon-based, links that react with a … Terms of Use and Privacy Policy: Legal. Often, I receive a call from a facility manager who has been tasked with coating his or her production floor. Polyurethanes are the “icing on the cake”. Or call us for help with choosing between epoxy and polyurethane concrete repair products at 631-298-6300. They are both light reflective, easy to clean, and long lasting. Chemically, both epoxy and urethane are polymers, or large molecules that contain a repeating structure. Like epoxy, the 2 components are mixed before they are injected into a foundation crack. As polyurethane is more durable than rubber, it can be used in cases of high stress and offers a certain amount of flexibility but remains strong. It all depends on what your project is as to whether you would choose epoxy resin or polyester resin. Epoxy Vs. Polyurethane: Which is the Best Resin for Your Driveway?

Résine époxy VS Polyuréthane : avantages et inconvénients. cloth however the epoxy laminate requires much less labor to fair. • Damaging or getting a crack on it is almost impossible, this is because of the high durability of epoxy resin. “For a general industrial or commercial application, the vast majority of the time I would recommend, at minimum, a three coat system consisting of an epoxy primer, an epoxy build-coat and a polyurethane topcoat,” I respond. We did find that, on a strength-per-weight basis, epoxy resin and carbon-fiber reinforcement offered the best resistance to penetration—even better that Kevlar. Upon curing, the epoxy build coat(s) provide a hard, durable surface. Although the name polyurethane gives an idea that the polymer consists of urethane monomers, it in fact, consists of urethane linkages, not monomers. Polyurethane is also a polymer material that contains urethane linkages. Polyurethane (or urethane), used for foundation crack repair applications, while not necessarily a 2 component blend, can have 2 components; the polyurethane resin and an activator, or accelerator. “What’s the difference with epoxy vs polyurethane coatings?”. • Epoxy is preferred in most industries as it sets much faster than resin. Most of the times, this polymer material shows high chemical resistance and high-temperature resistance but low flexibility. We recommend concrete preparation by mechanical means, such as diamond grinding or abrasive shot blasting methods. It’s not a matter of choosing one over the other, but a matter of utilizing both to achieve the desired result: Epoxy primers for bonding the system to concrete, epoxy build coat(s) for total system build/thickness, and polyurethane topcoats for enhanced physical performance, chemical-resistance, safety and aesthetics. Available here Epoxy and polyurethane are great for protecting your floor against stains, damage, chemicals, oils, and wear. They are also not as abrasion and chemical-resistant as polyurethanes. The upsides of using polyurethane are: Superb look. When choosing a resin to coat a concrete floor, companies want to make the best choice, which is usually reduced to either epoxy vs polyurethane. 3. Or else, epoxy resins can react with some other compounds such as; These are co-reactants. To cover wood, a laminate using epoxy resin and 10 oz, cloth will yield a much better job than 10 oz. “What Are Epoxy Resins?” ThoughtCo, ThoughtCo. Polyurethane coatings perform very similar to Polyaspartics but they take longer time to cure (at least 24 hours) and need to be applied very thin (4 to 6 mils per coat) Polyurethane coatings are used mostly top coats over Epoxy coatings. 4. Polyurethane resin, on the other hand, is up to 50 times more expansive than epoxy resin, making it far more resistant to cracking and therefore suitable for indoor or outdoor use. 6. Video of the Day Volume 0% The epoxy resin is less toxic to the board builder and the environment. Additionally, the offer excellent resistance to staining from hot or cold tires. 5 days for base and 8-12 hours for overcoats undercuts epoxy cure times but disrupts the use of your space significantly. Quick comparison between Epoxy Resins and Polyurethane Resins formulated for Concrete Crack Injection ... Epoxy resin needs to be contained in a crack until cured sufficiently to achieve full strength. A particular draw of using PU foam is that it is closed cell—meaning it won’t easily soak up resin or water (should you ding your board), which helps keep the board light. It resembles plastic with more durability. Both epoxy and polyurethane are polymer materials. A complete coating system is only as good as its initial bond to the concrete substrate. Moreover, polyol also should have at least two hydroxyl groups per molecule. However, using an epoxy-based resin will ensure that the product cures hard and bonds securely to the surface. De manière générale, ce genre de revêtement de sol est utilisé dans le but de couvrir un entrepôt, ou de grands espaces. It is a form of polyurethane. cloth and polyester resin. However, epoxy and polyurethane can be used together to create a very strong flooring system. He has over 15 years of marketing and sales support experience in the protective coatings industry. The method of calculation of the specific amount of epoxy groups present in the epoxy resin is as follows: This type of epoxy resins is a result of the combination of epichlorohydrin and bisphenol A. this combination gives bisphenol A diglycidyl ethers. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. Isocyanates and polyols undergo polymerization to form a polyurethane. The term epoxy is used to name epoxy resins that consist of epoxy functional groups in a repeating pattern. Polyurethane tends to be the most difficult resin to work with. This thickness allows the coating to chemically bond to the epoxy primer, and is thick enough to self-level and fill minor concrete blemishes and hairline cracks. They cannot be used as a complete system in itself. Polyurethane really needs to go on in individual coats to build up to a finish, which means you shouldn’t spray it on to the wood. Here we use bisphenol F in the place of bisphenol A, but the way of formation of the polymer is same as the bisphenol A epoxy resin (as discussed above). Chemical-Resistance: Polyurethanes are resistant to a broader range and concentrations of chemicals. 1. • Epoxy is resistant to water, heat, and chemicals whereas resins are not. The unit for this measurement is “mol/kg”. This polymer material has a low viscosity at room temperature. Bonding to Concrete: Provided the concrete substrate is properly prepared to receive a coating, epoxies are excellent for mechanically bonding to concrete. In this guide, we’ll compare epoxy resin and polyurethane resin: keep reading to learn more. When it comes to epoxy vs polyurethane coatings, the important take-away is to realize that both product technologies work well in conjunction with each other to produce a durable, long-lasting flooring solution. Overall, epoxies are the preferred materials for priming properly prepared concrete substrates, and providing ‘build’ or film thickness that can hide small blemishes or hairline cracks on the concrete surface. Epoxies are fairly easy to install, exhibit ample working time, and are fairly cost-effective when compared to other industrial flooring solutions. Flexible and elastic properties go to both of these options and each substance is used in the automotive industry, in the manufacture of certain parts. Resin coatings, such as epoxy or polyurethane, help make flooring materials meet the needs of various industries. Resin vs Epoxy: below is a list of these main resin categories: Polyester Resin: This is not an actual epoxy but is rather an unsaturated synthetic resin; Epoxy Resin: This type is supplied in 1 or 2 component forms; Polyurethane Resin: This is also not an actual epoxy but is rather a synthetic resin or plastic Figure 02: A Chair made from Polyurethane.

It can be overwhelming at first. UV Stability: Polyurethanes exhibit excellent UV-resistance. Polyurethanes can withstand high temperatures. Even if some of the other more expensive materials can be compared with resin in terms of longevity and quality, the cost-effectiveness, as well as its water-permeable nature, simply makes resin the more practical choice. There are certainly different types of epoxy coatings formulated to address a different desired performance result. Like epoxy, it is a 2-part component that mixes resin with a catalyst to cause the curing reaction that makes the material hard. Epoxy adheres to wood much better than polyester does. The urethane linkage forms when the –N=C=O group of isocyanate react with the –OH groups of alcohol to form a urethane linkage (-NH-C(=O)-O). Odor. Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form The latter has very good abrasion resistance, but it did not resist point loading as well as the carbon fiber/epoxy laminates. In summary – Epoxy vs Polyurethane. Unfortunately, I’m not familiar with wood fillers. Polyurethane is a polymer material that has urethane linkages. It takes an age to dry. Learn the differences between epoxy vs polyurethane coatings. Epoxy is made from epoxide and polyamine as a resin and hardener blend. Flexible and elastic properties go to both of these options and each substance is used in the automotive industry, in the manufacture of certain parts. Epoxy is more plastic in texture and forms a hard bond once cured. Not sure what type of polymer floor coating system your facility requires? It's said that one pouring of epoxy resin is "equal to 60 coats of polyurethane" in thickness, but it isn't necessary to use a resin just to get a high gloss effect. Epoxy vs Resin • Epoxy is the name of an ingredient as well as the end product of epoxy resin manufacturing. Can I use any kind of paint on the cast piece? PU/PE are built using a polyurethane foam blank and then glassing it with a polyester resin. One of our all-time most popular posts on Allthingsflooring.com is “Epoxy vs Polyurethane – which will you choose”.As this has proved to be such an in-demand topic, we thought we’d follow up with a post that looks into these two resin chemistries in a bit more depth. This polymer material is linear and is semi-solid crystalline materials. For concrete floor coating applications, the most durable, longest-lasting coating systems usually include the use of both epoxy and polyurethane. Epoxy is valued for its phenomenal bonding strength and electrical conductivity. As described above, epoxy is lighter, stronger, and more environmentally friendly. Polyurethane vs Rubber. An old EPS blank can be broken down and recycled into a new blank. “Polyurethanes.” The Essential Chemical Industry Online. Polyester resin is most commonly used in the construction of molded reinforced fiber and composite products, so its mechanical properties … Epoxy resin dries, or cures, to a very hard, unexpansive surface and is only suitable for indoor use. Of course, concrete preparation is a crucial part of establishing a proper bond. There are similarities between these substances, but their differences are more apparent and each industry seems to have its own preference. Polyurethane is another resin for floor coating concrete and steel. “I thought all floor coatings were ‘epoxy’,” the facility manager quips. Reply. This chemical protects against damage, UV rays, and water. It all depends on what your project is as to whether you would choose epoxy resin or polyester resin. Polyester is far less pleasant to work with than epoxy. The blending of the 2 components for each resin type creates a material with the requisite properties for professional crack injection repairs. Epoxy or epoxy resin is a class of polymer material consisting of epoxy functional groups. Polyurethane will not bond as wide a range of materials as epoxy resin will but in the case of fiber, wood, leather, etc. The monomers for epoxy resins are phenols and epichlorohydrin, but the monomers may vary depending on the type of epoxy resin. ( CM-15 , PC-155 , PC-275 , PC-650 ) – Polyamide Epoxies: Polyamide Epoxies are one of the older epoxy technologies that are still used today. 2. This makes polyurethane coatings more resistant to scratches and similar damage and is why you’ll often find urethane resin floors in heavy traffic areas – such as multi-storey car parks. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry. It is formed when isocyanates react with water or polyetheramines to create a urea linkage. But which material should you choose for your floors? Epoxy Benefits Epoxies come in a variet This resin has many different uses, besides just as a floor coating. EPS foam is also more environmentally friendly than polyurethane because it can be recycled and re-purposed. If we increase the amount of bisphenol A (compared to epichlorohydrin), it provides high molecular weight polymer material. Polyurethane resin, on the other hand, is up to 50 times more expansive than epoxy resin, making it far more resistant to cracking and therefore suitable for indoor or outdoor use. Sawdust will take up ‘water stains’ when mixed with resin, unless it is sealed first. 1. Epoxy boards also tend to be a better option for beginners as they are lighter, float better, and are more difficult to ding. Does hardened epoxy still "dent" with enough pressure? We frequently get asked about the difference between epoxy resin and polyester resin. Polyester laminating resin doesn't fully cure while exposed to air, so when it is used for lay-up, every application joins to the previous one on a molecular level. Epoxy resins can resist moderate temperatures. Polyurethanes "dry" in a fairly short time, but resins "cure" instead of drying and that takes at least 24 hrs. This creates a well-adhered system base that will allow subsequent build and topcoats. What is Epoxy? The difference between epoxy and polyurethane is that the epoxy resin contains epoxide groups whereas polyurethanes contain urethane linkages. 7875 Bliss ParkwayNorth Ridgeville, Ohio 44039, info@protectpoly.comWe reply within 24 hours, Sean Walsh is the Marketing & Product Development Manager of Protective Industrial Polymers, a company that manufactures high-performance resinous floor coatings for industrial manufacturing environments, which has a keen focus on developing unique solutions for managing electrostatic, microbial, chemical, explosion and safety risk concerns. What is Epoxy They also harden differently. @Linda, I would use a very hard curing epoxy or even a polyurethane resin. Novolac is another class of epoxy resin that has higher functionality than standard DGEBA resulting in a higher crosslink density. These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Some other names for these co-reactants are hardeners or curatives. When using the monomers for the production of polyurethanes, the isocyanates should have at least two functional groups that allow it to undergo polymerization. These polymers get their name according to the repeating linkages present in the polymer material instead of the monomers used for the production. Increased Impact and Abrasion Resistance: Polyurethanes exhibit excellent impact and abrasion resistance, providing up to four times longer life than uncoated epoxy floors. In summary – Epoxy vs Polyurethane. “Epoxy.” Wikipedia, Wikimedia Foundation, 19 Apr. Learn the differences between epoxy vs polyurethane coatings. You want a floor that is strong, like your business, and worry-free. These polymers form via glycosylation of aliphatic alcohols or polyols. A: Acrylic resin (but not acrylic emulsion, which is the basis of acrylic paint) is a thermoplastic, which means it is one of a group of plastics which can be heated and manipulated repeatedly, whereas polyester resin and epoxy are thermosetting plastics, which use heat or a catalyst to solidify into a solid mass that won’t melt down. Polyurea is a subgroup of polyurethane. The reactions between the monomers in this polymerization are an exothermic reaction in which heat is given off from the reaction mixture. Advantages – The major benefit of epoxy is its strength. Proper Floor Cleaning and Maintenance Can Help Ensure Longer Service Life. Polyurethane coatings perform very similar to Polyaspartics but they take longer time to cure (at least 24 hours) and need to be applied very thin (4 to 6 mils per coat) Polyurethane coatings are used mostly top coats over Epoxy coatings. Epoxy resins less flexible and less abrasion resistant. Available here, 1.’Epoxy’ By Dzhang2680 – Own work, (CC BY-SA 3.0) via Commons Wikimedia We can leave those intracacies for another blog article.
We frequently get asked about the difference between epoxy resin and polyester resin. Epoxy carries protections for impact, scratches, water, and chemicals. 5.
