Abstract: A chemical resistant water reducible coating composition comprising:
(i) an active hydrogen functional water dispersible polyurethane polymer;
(ii) a crosslinking agent reactive with the active hydrogen functional polymer under curing conditions:
(iii) a mixture of polymeric beads dispersed within the polymer wherein the mixture comprises:
(a) polyolefin beads having a mean particle size as measured by laser diffraction analysis of about 5 to 40 microns; and
(b) polyurea polymeric beads having a mean particle size of less than 15 microns
wherein the mixture of polymeric beads is present at a level to provide an 85° gloss less than 3 and a 60° gloss less than 3.
