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 75 um DFT
2. Apply Vitreset 416 MIOX Buildcoat to achieve 100um DFT
3. Apply Vitreflon 630 Fluoropolymer topcoat to achieve 50μm DFT
VITREPHOS 580 combines a high loading of zinc phosphate in an air impermeable matrix of hard epoxy resin. Its excellent adhesion and its corrosion inhibiting “throw” renders VITREPHOS 580 very effective in the control of rust on mild steel substrates. It usually forms the primer or intermediate coat of a heavy duty paint system in combination with a durable VITRETHANE Polyurethane topcoat finish.
VITRESET 416 MIOX is a high performance epoxy intermediate / base coat that gives excellent adhesion and corrosion barrier properties. Micaceous Iron Oxide coatings are renowned for their ability to stand the test of time, and withstand both moisture ingress and substrate movement to ensure long-term asset protection.
VITRETHANE 630 is a solvent based two pack acrylic urethane with very good exterior durability and excellent application properties. It is quick drying and well suited to onsite application.
