EPOXY ZINC PHOSPHATE PRIMER TWO-PACK
 
A general purpose epoxy resin based anti-corrosion primer designed for application direct to blast cleaned steel. This product is formulated on the latest anti-corrosive pigments and forms an excellent epoxy protective system for external use. It is not intended for continuous water immersion, or prolonged exposure to highly acidic atmosphere or spillage. Although the primer has good intrinsic chemical resistance, attention should be paid to the specified recoating schedule especially where strongly aggressive chemical atmosphere are to be encountered.

SURFACE PREPARATION
Structural steelwork Blast clean to BS4232:1967 'Second Quality' (Swedish Standard SA 2 ½) or SSPC SP6 minimum and apply Epoxy Zinc Phosphate Primer Two-Pack direct. Prime immediately after blasting. If this is impractical both blasting and priming must be completed within the same working day and before the standard of blasting has deteriorated. Alternatively Epoxy Zinc phosphate Primer Two-pack may be applied over an appropriate protective primer. This should be clean, dry and firmly adhering. (Polyvinyl butyral shop primers should not be used under conditions of continuous immersion or, in conjunction with cathodic protection).Must be clean, dry and grease free.
