ABSTRACT:
This invention is concerned with certain vinyl resin coating compositions in which the vinyl resin binder or film-forming component is normally dissolved in an organic solvent which is volatilized after application of the composition to the surface of substrates to be finished. The vinyl resin component is generally of high molecular weight and it is normally difficult to obtain a reasonable viscosity in the coating composition without excessive dilution with organic solvent and the necessity to apply a plurality of coats to obtain the desired protective thickness. The present invention has been found to alleviate or reduce this difficulty in the particular solution coating compositions with which it is concerned, namely thermoplastic vinyl or acrylic polymer solutions, polyvinyl acetals, and chlorinated polyisoprene containing about 64-65% chlorine. In the compositions of the present invention, the vinyl resin is dissolved in an organic liquid vehicle which consists essentially of a non-volatile reactive monomer including dicyclopentenyl acrylate or methacrylate or comprises a predominant proportion of such non-volatile reactive monomer. Also essential components are a siccative, that is, a polyvalent metal-containing complex or salt that catalyzes the oxidative curing of the mixture of the reactive monomer and the film-forming polymeric binder, and a fugitive agent, that is, a volatile oxime stabilizer, for inhibiting the action of the oxidation catalyst. The compositions may also contain pigments, rheology-control agents, pigment-dispersing agents and other components common in the coating art.
