Abstract:
A method of producing a refinish primer system comprising:preparing a refinish primer composition comprising an organic solvent based dispersion having a solids content in the range from about 45 to 70% by weight, wherein said solids comprise:from about 10 to about 50% by weight of crosslinked acrylic polymer microparticles having a diameter of 0.1 to 10 microns which are insoluble in the organic solvent and are stabilized in the solvent system by steric barriers, said steric barriers containing at least two segments, one segment being soluble in the organic solvent and the other segment being substantially insoluble therein;from about 30 to about 60% by weight of an oxidatively-curable resin; andfrom about 15 to about 40% by weight of one or more additional ingredients selected from the group consisting of corrosion inhibitors, inert fillers, pigments, surface builders and mixtures thereof;applying said refinish primer composition to a bare substrate surface to form a protective layer; andapplying on said protective layer a primer surface composition comprising an organic solvent, an oxidatively-curable or plastic resin and an inert filler to form a refinish primer system.
