High adhesion anti rust and anti-corrosion epoxy zinc rich primer

Short Description:

Epoxy zinc-rich primer is a two-component paint composed of epoxy resin, ultra-fine zinc powder, ethyl silicate as the main raw material, thickener, filler, auxiliary agent, solvent, etc. and curing agent.




*Product Features:

1. The paint is rich in zinc powder, and the electrochemical protection of zinc powder makes the paint film have outstanding anti-rust performance;
2. Good mechanical properties and strong adhesion;
3. Has excellent wear resistance;
4. Good oil resistance, water resistance and solvent resistance;
5. It has extremely negative protection and outstanding heat resistance. When the electric welding is cut, the zinc mist generated is small, the burn surface is less, and the welding performance is not affected.

*Product Application:

Suitable for metallurgy, containers, ships, bridges, towers, oil pipelines, vehicle manufacturing, steel shot pretreatment lines, steel structure equipment surface as a base anti-rust primer, can also be used for anti-corrosion layer on galvanized surface.https://www.cnforestcoating.com/protective-coating/

*Surface Treatment:

All surfaces to be coated should be clean, dry and free from contamination. Before painting, all surfaces should be in accordance with the ISO8504: 2000 standard evaluation and processing.

  • The scaled steel is blasted to Sa2.5 grade, surface roughness is 30-75μm, or pickled, neutralized and passivated;
  • Oxide-free steel blasted to Sa2.5 grade, or polished to St3 grade with pneumatic or electric elastic grinding wheel;
  • Steels coated with workshop primer paint film damage, rust and white rust on zinc powder primer should be derusted twice, white rust is removed and polished to St3.
