METAL PRIMER ZINC CHROMATE

Zinc Chromate primer is an alkyd based rust-inhibitive primer protecting ferrous metal surfaces against corrosion. Its formulation rich in high performance zinc chromate pigments provides excellent resistance against rust and oxidation.

It is recommended for steel structures and surfaces exposed to corrosive environments. It is also recommended for overcoating of zinc primed steel and for applications on light metal alloy surfaces. It is used for only air-drying applications. It can be overcoated with Alkyd based paints. It is suitable for interior and exterior use for alkyd systems.

Surfaces should be solid, clean and dry, free from oil, grease, salt, dust and other contaminants.

1. Alkaline and acid surfaces should be cleaned and neutralized.
2. Deteriorated previous coatings, weak and blistered paints or chalky substances should be removed by scrapers, paint removers or flame spraying.
3. Non-disintegrated paints or glossy surfaces of previous coatings should be roughened slightly with sand paper to ensure good undercoat adhesion.
4. Corroded and/or damaged areas should be blast cleaned.
5. Other surfaces: For aluminum substrates, thorough washing and sweeping with a nonmetallic blast medium is required.
