Epoxy primers are primarily recommended as the first base coat over bare steel or concrete. These base coats or epoxy primers can be used over fiberglass, plastic or the black iron phosphate coating as well. Epoxy primers have strong adhesion, good mechanical ability, and durable chemical resistance in wet and high-humidity environments. Epoxy primer’s bonding capacity is excellent and it produces a good surface finish. Epoxy primers not only offer excellent adhesion to metals, but also serve as a proper base for extra undercoat products and top coats.
