AUTOXIDISABLE COATING COMPOSITIONS CONTAINING DISPERSED NON-CROSSLINKED POLYMER MICROPARTICLES

Coating compositions are described in which the film-forming material consists of (a) 30-85% by volume of disperse particles of size 0.01 - 20 microns, of which not less than 50% by volume are non-cross-linked condensation polymer microparticles, and (b) 70 - 15% by volume of a liquid continuous pha...

Zusammenfassung:	Coating compositions are described in which the film-forming material consists of (a) 30-85% by volume of disperse particles of size 0.01 - 20 microns, of which not less than 50% by volume are non-cross-linked condensation polymer microparticles, and (b) 70 - 15% by volume of a liquid continuous phase of viscosity 0.1 poise which is curable to a film-forming polymer by means of an autoxidative (i.e. air-drying) mechanism; the particles (a) being stable dispersed in the liquid (b) in a deflocculated state by means of an amphipathic steric stabilising agent. Typically, the polymer microparticles may be composed of a non-cross-linked polyester and the liquid continuous phase of a drying-oil fatty acid ester of a pelyol, optionally in conjunction with a coreactive liquid such as an acrylic or methacrylic ester of a higher alcohol or a polyol.
