GPS 1261B V580, V790 for Galvanized Steel Coating In C2 Env. 15 – 25 Years

Surface Preparation:

 Preliminary cleaning:

Thoroughly degrease the surface to remove all contaminants as per AS 1627.1

Brush (sweep) Blast Clean as per Std. AS 1627.4 Appendix D, or if not possible hand abrade thoroughly to achieve a surface profile of 10 -15 microns.


1. Apply Vitrephos 580 Epoxy Primer to achieve 100 um DFT

2. Apply Vitrethane 790 Fluoropolymer topcoat to achieve 50μm DFT


  • Fascias and facades

  • Structural steel and roofing


VITREPHOS 580 combines a high loading of zinc phosphate in an air impermeable matrix of hard epoxy resin. Its excellent adhesion  renders VITREPHOS 580 very effective for galvanized steel substrates. It usually forms the primer or intermediate coat  in combination with a durable VITRETHANE Polyurethane topcoat finish.

VITREFLON 790 is a high performance two pack fluoropolymer resin base top coat that can cure at room temperature or under low bake conditions. This gives excellent UV resistance and weathering performance. It has good application properties and chemical resistance. The ‘State of the Art’ technology lowers the lifetime maintenance cost of coating in a variety of environments.
