KingCoat PA550®
High performance polyurethane acrylic hybrid enamel coating.
Overview
KingCoat PA550 is high performance floor and wall coating based on hybrid combination of acrylic- polyurethane resins. It is supplied as a two pack material in pre-weighed quantities ready for on-site mixing and use. KingCoat PA550 is easily sprayed, brushed or rolled to concrete and steel substrates in a two coat application, typically applied at a wet film thickness of 200 - 250 microns per coat without sagging. KingCoat PA550 is available in a standard grey colour, other colours are available subject to minimum order quantities.
