Coatings

Epoxy / Epoxy-PE / Acrylic

Epoxy offers outstanding adhesion and corrosion resistance but poor UV stability, so it's used as a primer or back-coat rather than an exposed finish. Epoxy-PE pairs epoxy's adhesion with a polyester topcoat for better exposed performance. Acrylic is a related economical system for cost-sensitive interior or low-UV use.
