A two-pack zinc rich organic
primer designed to prevent corrosion on blasted steel during Fabrication,
or transit to site. Zinc rich Epoxy Primer has good application properties
and is Moderately quick drying so that it can be used as a shop primer
where very rapid dry to a Handling state is not required, and is also
very suitable as a holding primer for progressive blast cleaning of
large areas on site. It provides an excellent primed surface for a
wide range of sophisticated plant systems, and can be used without
special pretreatment. Except in marine or chemically polluted atmospheres
where thorough surface cleaning, or even relasting, is advisable to
remove zinc salt formation from surface before overcoating.
OF WET PAINT (TYPICAL FIGURES)
Blast clean to BS4232:1967
'Second Quality'(Swedish Standard SA 2 ½) minimum or SSPC SP10. Prime
immediately after blasting. If this is impractical blasting and priming
must both be completed within the same working day and before the
standard of blasting has deteriorated.
Primer for Heavy Duty Coating
paint systems based on Epoxy Chlorinated Rubber of Vinyl Resins. Not
to be over coated with Oil-containing products.
WELDING AND FLAME
At the recommended dry film
thickness. Zinc Rich Primer Two-Pack does not normally affect the
speed or working of the welding and flame cutting equipment currently
used.Automatic twin-fillet submerged-arc welding and some forms of
CO gas-shielded welding may be exceptions.
