Epoxy Benefits Epoxies come in a variet As described above, epoxy is lighter, stronger, and more environmentally friendly. • Epoxy is resistant to water, heat, and chemicals whereas resins are not. 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). Difference Between Copolymer and Homopolymer, Difference Between Polystyrene and Polypropylene, Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form, Difference Between Coronavirus and Cold Symptoms, Difference Between Coronavirus and Influenza, Difference Between Coronavirus and Covid 19, Difference Between Oleic Acid and Elaidic Acid, Difference Between Apple A7 and A8 Processors, Difference Between Microarray and RNA Sequencing, Difference Between Filgrastim and Lenograstim, Difference Between Parallel and Antiparallel Beta Pleated Sheets, Difference Between Sodium Citrate and Citric Acid, Difference Between Hypersil and Inertsil Column, Difference Between Trypanosoma Cruzi and Trypanosoma Rangeli. 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. 1. 2018. Sawdust will take up ‘water stains’ when mixed with resin, unless it is sealed first. 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. There are certainly different types of epoxy coatings formulated to address a different desired performance result. PU/PE are built using a polyurethane foam blank and then glassing it with a polyester resin. Polyurea is a subgroup of polyurethane. Novolac epoxy resins for high temperatures. Increased Impact and Abrasion Resistance: Polyurethanes exhibit excellent impact and abrasion resistance, providing up to four times longer life than uncoated epoxy floors. It is formed when isocyanates react with water or polyetheramines to create a urea linkage. These epoxies are designed by having the curing agent with a small amount of epoxy resin. 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). When looking for flooring for your business, there are many options out there. Epoxy creates a hard protective coating that bonds to concrete or steel. However, epoxy resins will begin to gel in as quick as 20 minutes, whereas casting resins may take upwards of 18 hours to gel. Video of the Day Volume 0% They also harden differently. Polyurethane will not bond as wide a range of materials as epoxy resin will but in the case of fiber, wood, leather, etc. Odor. For concrete floor coating applications, the most durable, longest-lasting coating systems usually include the use of both epoxy and polyurethane. 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. 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. Figure 02: A Chair made from Polyurethane. Epoxy resins can resist moderate temperatures. 5. As a varnish style coating. Summary. Here’s a quick breakdown on the differences between epoxy resin and polyester resin. Epoxy resin makes a strong and durable tabletop. What is Polyurethane It all depends on what your project is as to whether you would choose epoxy resin or polyester resin. 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. 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. Epoxy is an organic compound. 2. Reply. Polyurea is a subgroup of polyurethane. In very simple terms, a typical two-part epoxy coating contains a resin side and a hardener side. Polyurethane may be the most durable resin of them all and that means you won’t need to do as much maintenance when you choose polyurethane. Novolac epoxy resins form when phenols react with formaldehyde and undergo glycosylation with epichlorohydrin. Available here  Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form 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. Urethane is composed of organic, or carbon-based, links that react with a … • Epoxy is preferred in most industries as it sets much faster than resin. Resin and epoxy are both adhesives commonly employed in the construction industry. Proper Floor Cleaning and Maintenance Can Help Ensure Longer Service Life. Isocyanates and polyols undergo polymerization to form a polyurethane. Moreover, polyol also should have at least two hydroxyl groups per molecule. It’s not as strong as epoxy but there are some occasions when it might do a better job. Take our FREE Flooring Self-Assessment today! UV Stability: Polyurethanes exhibit excellent UV-resistance. Build/Thickness: Epoxy build coats are typically installed at 8 to 15 mils per application. 1. • 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. With 98% solids, polyurea is 4x stronger and yet 98% more flexible than epoxy. Is Floor Cleaning and Maintenance Part of Your Safety Program? Optional wear and safety additives can be incorporated into the topcoat texture. Finishes: Polyurethane finishes can range from satin to semi-gloss to high-gloss. 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. That being said, there might be a few dilemmas and … If the repair is critical or structural, an epoxy resin should be considered. Installation & Performance: Upon curing, the epoxy build coat(s) provide a hard, durable surface with good impact resistance. Epoxy or epoxy resin is a class of polymer material consisting of epoxy functional groups. With a limited pot life and risk of humidity issues, your staff needs to work quick and smart for good results. Johnson, Todd. I’ve been researching products on your website. Although it sets up much faster, it has … 4. Epoxy carries protections for impact, scratches, water, and chemicals. The difference between epoxy and polyurethane is that the epoxy resin contains epoxide groups whereas polyurethanes contain urethane linkages.
