Epoxy primer has good adhesion to properly treated metal surfaces. The paint film is hard, resistant to various media used by aircraft, and has good corrosion resistance. Widely used in various aircraft. The base material, pigments, and fillers of the epoxy resin after plant esterification are ground into a color slurry, and then a small amount of amino resin, driers and solvents are added to make the epoxy primer zinc yellow epoxy ester primer currently used in large quantities in my country.

The anti-rust pigment is zinc chromate, which has good corrosion resistance for magnesium and aluminum alloys. The paint film is tough, has good adhesion, is water-resistant and durable. Compared with alkyd primer and acrylic primer, zinc yellow epoxy resin primer has better performance. Mainly used for internal frames, aluminum profiles, components, equipment and the inner surface of aluminum skins of various aircraft. Epoxy primers include one-component zinc yellow epoxy ester primer and two-component epoxy polyamide primer.

Zinc yellow epoxy polyamide primer is used in conjunction with polyurethane topcoat and can be used on passenger and military aircraft.
Compared with the one-component zinc yellow epoxy ester primer, the two-component epoxy polyamide primer has better adhesion, flexibility, gloss retention and tempering resistance. Two-component epoxy polyamide primer, one component is epoxy resin, the solvent is a mixed solvent of hydrocarbons, aromatic hydrocarbons and alcohols, and the other component is a curing agent, low molecular weight polyamide resin. The active functional amino group in the polyamide resin reacts with the epoxy group in the epoxy resin to cross-link into a network structure, which has good elasticity and adhesion. Polyamide resin is not only a curing agent for epoxy resin, but also a plasticizer, which enables the resin to maintain its toughness for a long time, improves the brittleness of epoxy resin, and the curing reaction can be carried out at room temperature.
