Autoxidizable coating compositions |
摘要 |
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 cross-linked polymer microparticles, and (b) 70-15% by volume of a liquid continuous phase of viscosity 0.1-20 poise which is curable to a film-forming polymer by means of an autoxidative (i.e. air-drying) mechanism, the particles (a) being stably dispersed in the liquid (b) in a deflocculated state by means of an amphipathic steric stabilizing agent. Typically, the polymer microparticles may be composed of a cross-linked polyester and the liquid continuous phase of a drying-oil fatty acid ester of a polyol, optionally in conjunction with a coreactive liquid such as an acrylic or methacrylic ester of a higher alcohol or a polyol.
