Coating composition for acrylics

Claim 1

A coating solution, consisting essentially of a. from 10 to 40 percent by weight, based on the total weight of the coating composition, of a partially hydrolyzed siloxane substance obtained by hydrolyzing in water, at 50° to 80° C., for one to 10 hours, a substance selected from the group consisting of 1. a hydrocarbon trialkoxy silane having the formula R'Si(OR") 3 , wherein R' is selected from the group consisting of alkyl having one to 4 carbon atoms, phenyl and vinyl, and R" is alkyl having one to 4 carbon atoms, and 2. co-condensation products of (1) and from 1 to 40 weight percent of phenyl or vinyl trialkoxy silane wherein alkoxy has one to 4 carbon atoms, b. from 0.05 to 5 percent by weight, based on the weight of component (a), of one or a mixture of salts selected from the group consisting of alkali metal salts of naphthenic acid and zinc salts of naphthenic acid, c. from 5 to 30 percent by weight, based on the total weight of the coating composition, of acetic acid, and d. the balance is one or a mixture of inert organic solvents for components (a) and (b), said inert solvent or solvents being present in an amount sufficient, in combination with component (c), to completely dissolve components (a) and (b).
