This product has exceptional
film build land sag resistant properties, and is specially designed
for use by airless spray to give economic application in very thick
film i.e. upto 250-300 microns (10-12 Mils) per coat. Its main use
is as the intermediate coat in an Epoxy High build protective system,
where maximum chemical and abrasion resistance properties are required.
It has good chemical, water and solvent resistance and can be used
as a low-gloss, high-build finish coat for external and internal use.

curing
The curing of Epoxy resin-based
coating is temperature dependent. It is seriously retarded below
5ºC (41ºF).
Epoxy Bildcote is normally
applied over Zinc Rich Primer Two-Pack, Epoxy Zinc Phosphate Primer
Two-Pack, Epoxy Protective Primer Two-Pack. The protective primer
must be clean, sound and firmly adhering. (Polyvinyl butyral shop
primers should not be used under conditions of continuous immersion
or in conjunction with cathodic protection). The removal of contamination
must include washing with fresh water to remove soluble salts.
PAINT SYSTEM
One or two coats Epoxy Bildcote
to a minimum thickness of 200 Microns (8 Mils) followed by Epoxy Finish
if required. When used as a self-finish the minimum dry film thickness
must be 250 Microns (10 Mils).
