Modified Epoxy Non-ferrous Metal Primer

Both epoxy zinc-rich primer and epoxy non-ferrous metal primer are industrial paints. They are both anticorrosive and antirust primer products that can be widely used in a variety of coating environments. The difference between them:

• Product ingredients:

Epoxy zinc-rich primer: a two-component paint, a special coating product composed of epoxy resin, zinc powder, main raw materials, thickeners, fillers, additives, solvents, etc.

Epoxy non-ferrous metal primer: It is a product made up of epoxy resin pigments ground into a color paste as component one and phenolic resin as component two.

• Product appearance:

Epoxy zinc-rich primer: Because zinc powder is used in epoxy zinc-rich primer as an anti-rust pigment, it is dark gray, so epoxy zinc-rich primer is usually only gray.

Epoxy non-ferrous metal primer: Due to the use of lead chrome yellow pigment, the product appearance of epoxy non-ferrous metal primer is yellow.

• Product use:

Epoxy zinc-rich primer: It is mainly suitable for storage tanks, containers, steel structures, steel pipes, offshore platforms, ships, seaport facilities, and base coatings for harsh anti-corrosion environments.

Epoxy non-ferrous metal primer: It can also be used as a primer for anticorrosive coatings for steel structures such as bridges, storage tanks, pipelines, and equipment. The advantage is that it is especially suitable for galvanized sheet, aluminum alloy and other non-ferrous metals. Adhesion is its advantage!

• Respective defects:

Epoxy zinc-rich primer: it is not suitable for use on smooth metal substrates.

Epoxy non-ferrous metal primer: It has a high VOC emission and serious environmental pollution! Heavy metals such as lead in the primer exceed the standard and pose a great threat to human health.

The paint on the surface of the galvanized sheet needs to use special paint to ensure excellent adhesion and protection. Ordinary paints, such as polyurethane paint, acrylic paint, zinc-rich primer, etc., are difficult to adhere to the metal surface, easily peel off the paint, and cannot achieve the effect of anti-corrosion or decoration at all. For galvanized surfaces and other non-ferrous metal surfaces, epoxy non-ferrous metal primer is required. It can adhere well to the surface of non-ferrous metals and has good adhesion with the topcoat.
