EPOXY HIGH BUILD
 
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.

SURFACE PREPARATION 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).
Pack size Base - 20 litres
