2K SOLVENTBORNE EPOXY ZINC-RICH ANTI-CORROSION PRIMER
PRODUCT DESCRIPTION
This is a two-component polyamide cured zinc-rich epoxy coating. It is a very high zinc dust-containing product. It provides excellent corrosion protection as part of a complete coating system. Suitable for carbon steel, repair of inorganic zinc silicate coating, and damaged galvanized steel substrates.
FEATURES & APPLICATION
Excellent cathodic protection, anti-corrosion, and wearing resistance;
Easy to reach high thickness and good application properties;
Good weather resistance, rapid drying;
Less burn during gas-cutting and welding;
Strong adhesion to the surface, good compatibility with various topcoats.
As a primer on sandblasted steel, epoxy zinc-rich primers can be used in combination with high-performance paints to further improve corrosion resistance. Mainly used as primer for steel surface of bridges, ships, petrochemical infrastructure, containers, steel structures, etc.
