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.

PREPARATION

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.
PAINT SYSTEM
One coat Epoxy Zinc Phosphate Primer, 50 microns
(2 Mils followed by one or two coats Epoxy Bildcote to a minimum
thickness of 200 microns (8 Mils) followed by Epoxy Finish)
