Primer like Epoxy Based Primer, Moisture Insensitive Primer, Water Based Primer. Techfloor, Adhere Queen, Adherex. Stick to bare metal, paints & fillers.
A sealer that is a non-porous finish. It is primarily recommended as the first base coat over bare steel. These base coats or epoxy primers can be used over fiberglass, plastic or the black iron phosphate coating.
This primer can also be used on cracks and dents. Its bonding capacity is excellent and 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 (paint).
Since paints in the automobile and marine industries are very important for resisting corrosion (rusting), epoxy coatings are widely used as primers to improve the adhesion of the metal surface. Epoxy primers are also used in structural steel coatings for high-build thickness with the application of only one or two coats.
