From an applicators point of view polyurethane floor resins are extremely sensitive to the presence of humidity. It is ideal as an anti-graffiti coating and has outstanding chemical and abrasion resistance. Polyurethane floors are therefore preferred • In spaces with foot traffic • In multideck car-parks since the elastic layer can act as a waterproofing layer • In freezing chambers where temperatures can reach -30oC 2. Usually these epoxies are economical and are used a primer and finish coat. You see examples of powder coating on a vast range of everyday appliances and household fixtures, such as stoves, refrigerators, laundry machines, tables and lamp vases. Polyurethane also has a clear advantage over epoxy when it comes to UV stability. If you want to upgrade your garage floor, or some other concrete surface using epoxy, it is important to understand what differentiates the two.This allows you to make the right decision for your desired aesthetic. Polyurethane is another resin for floor coating concrete and steel. UV Stability: Polyurethanes exhibit excellent UV-resistance. Some common applications for include control rooms, locker rooms, break rooms and concrete flooring for light traffic. Bond Polychem, Ahmedabad, Gujarat. You can apply polyurethane over any paint, as long as the surface is clean and prepared well to receive the polyurethane coat. Some common applications for include control rooms, locker rooms, break rooms and concrete flooring for light traffic. These epoxies can generally be used on steel, concrete, and galvanized steel. For over 40 years, Gulf Coast Paint has been helping owners and contractors determine the best coating solution for their specific need.

Epoxy Coatings vs. Polyurethane Coatings: Which One Should you Choose? When cured, epoxies are so tough they are used on bathtubs. These coatings are usually sold as finish and are usually applied at 2-3 mils DFT. (PC-240), – Phenalkamines: Phenalkamine cured epoxies are excellent for low temperature / cold weather applications. I use polyurethanes for hardwood flooring. (Chemical Resistant Urethane), which makes it a great choice for aircraft hangars, service bay floors and other high traffic areas due to its resistance to a wide range of chemicals including salt, oil, gas, grease, skydrol, caustic, and most acids that you may come in contact with your floor. Quick drying and easy to apply: Polyurethane paint is fast curing, meaning less downtime and associated losses.Like an epoxy it is easy to apply, but polyurethane has faster return-to-service times than epoxy. They’re not as high performing as the high solids and 100% solids epoxies but they offer a great solution in areas where there’s no aggressive chemicals. These coatings are used for exterior steel surfaces for long term protection. Acrylic Polyurethanes are usually made with an aliphatic compound which provides the long term stability needed in an Acrylic Polyurethane. They’re great choices for internal tank linings, secondary containment, pump pads, trenches, and other high exposure areas. Polyamide Epoxies are one of the older epoxy technologies that are still used today. (PC-636), – Polyester Epoxies: Polyester epoxies are a very unique, two component non-yellowing epoxy coating. Choosing Epoxies and Urethanes with Products – PDF. Epoxy should be used as the base coating (to bond to concrete) and the polyurethane can be used as a topcoat (flexible, scratch resistant, UV stable). These coatings are made with 100% Polyester resin which provides an extremely durable finish. Hello, Differences Between Epoxy vs.Polyurethane Thin Film Topcoats By Sophia Daukus on October 17th, 2016 in Commercial & Retail , Installation Epoxy and polyurethane thin film topcoats are two types of high performance floor coatings that can be used to strengthen, protect, and improve the aesthetics of an industrial flooring system. Polyester Polyurethanes are a true C.R.U. They have a short pot life – generally 20-40 minutes and they usually can’t be recoated until 6+ hours. However, polyaspartic aliphatic polyurethane is different. Epoxy creates a hard protective coating that bonds to concrete or steel. Most polyurethanes also have high VOC level and will have quite an odor when applied. Polyester Polyurethanes are a true C.R.U. These monomers combine with each other to form a … Polyurethanes do not bond well to concrete and do not exemplify the self leveling properties that epoxies do when applied to on these surfaces. Aliphatic polyurethane's are extremely flexible and allow for good impact resistant. They provide a hard finish that is very durable. Most novolacs are designed to handle 98% sulfuric acid and 37% HCL for splash & spillage. One of the benefits to epoxies are they are made with different amounts of VOC levels (volatile organic compounds)...this is the really smelly odor that the paint gives off. Grouts, Toppings & 100% Solids Epoxy Resins, Concrete Coatings:  A Guide to Selecting the Best Concrete Coating. Website by Dreamedia. 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. (PC-517, PC-555, PC-590, PC-1500, PC-1875), – Water Based Epoxies: Water Based Epoxies are great choices in less demanding areas. Epoxy paints are two-part paints which, unless mixed, will never cure. These epoxies are designed by having the curing agent with a small amount of epoxy resin. The term urethane and polyurethane has been thrown around a lot in the industry and used by sales & marketing professionals to present their product in the best light. or 251-964-7911 for assistance on your upcoming coating project. ". When looking for flooring for your business, there are many options out there. stable. Polyurethane Coatings: Polyurethanes are known for their outstanding UV resistance, gloss retention and color stability. (CT-332, CT-352). Epoxy vs. Enamel . In fact, the lifespan of the PU system is roughly double that of the epoxy, clocking an impressive ten-year’s compared to the epoxy’s five. Another benefit is the use as binder to be mixed with metallic flakes, color quartz, and as a base coat for color flakes. These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing.
