Q: Should I use different powder for interior vs exterior applications?
A: There are many different types of powders. Epoxies are very durable and are the best for chemical and corrosive resistance. Epoxies provide excellent adhesion on metals. Epoxy does not fare well in the sun; the exposure causes fading. Epoxies are excellent for interior applications or as a base coat.
Polyesters are most common and offer flexibility, impact resistance, and chemical resistance. Polyesters provide a few years of good UV resistance as well. Polyesters come in many colors, gloss levels, and special finishes.
Super durable powders are excellent for exterior applications. They offer high impact and chemical resistance. They can be formulated in many colors, gloss levels, and special effects. Super durables are made to last and can retain their color for many years. Super durables exceed performance tests.
