Low gloss powder coating compositions

摘要

The invention is directed to a low gloss powder coating composition comprising a first component (a) and a second component (b). The first component (a) comprises a mixture of (i) at least one glycidyl group-containing acrylic resin having epoxide equivalent weight of from about 250 to about 1500 and glass transition temperature of from about 30° C. to about 80° C.; and (ii) a curing agent. The second component (b) comprises at least one carboxyl-group containing material having acid number of from about 10 to about 300 and is not substantially compatible with the first component (a). The two components are dry-blended to obtain the powder coating composition.
