Primers

Epoxy primers are used for a wide variety of materials due to their strong adhesion, good mechanical ability, and durable chemical resistance in wet and high-humidity environments. The ability of an epoxy primer to resist corrosion is related to its thickness; the thicker the epoxy primer layer, the better the protection. This primer can also be used on cracks and dents. Its 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 (paint). Epoxy primers are also commonly used to coat metal cans and containers, especially those used to hold acidic food, such as tomatoes.
