Let's talk coatings: Epoxy vs Urethane

Each product has its own pros and cons, and its place in an industrial setting. An epoxy is typically a more hard, rigid coating that is extremely durable under compression. The downside to this is that an epoxy can be brittle and prone to cracking if used improperly, where as urethanes are quite flexible and can easily absorb impact without cracking.

As shown in pictures 1 & 2 below, an epoxy will usually have a dull / matte finish once cured, while pictures 3 & 4 show the shiny urethane finish. The urethane has the ability to withstand extreme temperature changes (ie freezing temps, steam cleaning, moisture) and will not lose its color and gloss under UV rays, where an epoxy would not do as well. If outside and exposed to UV rays, the epoxy will "chalk" - the sun causes the materials in the coating to slowly break apart and release a fine, powdery material (similar to chalk).

Epoxies are generally more cost effective than urethanes, and can be a great option to protect heavy machinery, structural pieces and various parts that will be kept inside in a temperature controlled area. Though urethanes are more expensive, they are a fantastic choice to use when the customer wants a nice, scratch resistant finish, or for use outdoors / in heavy traffic areas / frequent handling. Both epoxies and urethanes have excellent corrosion resistance, but a urethane is usually required to be applied over a primer or epoxy in order to bond with the material it's coating.

Here at DSI, our preferred paint system is typically an epoxy over sandblasted steel, with a urethane top coat (as shown below). This way you get the strength and durability of an epoxy, with the weather and scratch resistance of the urethane, providing a protective shell for the coated parts to last years!
