Pinaka Etch Primer 4211
Pinaka Etch Primer 4211 is a two-component zinc tetroxy-chromate etch primer formulated to chemically etch and enhance adhesion on galvanized, aluminium, and other non-ferrous metal surfaces. Its low-viscosity system creates strong mechanical and chemical bonding, preventing premature delamination and ensuring long-term coating system durability. Designed for structural and industrial environments, the primer is compatible with spray and brush methods and functions as a critical adhesion-promoting basecoat for a wide range of topcoats.
