Procedure

The reaction product of 0.81 g. of zinc oxide, 9.91 g. of dimethyl-n-octadecyl [3(trimethoxysilyl)propyl] ammonium chloride, 10.0 g. of 28% aqueous ammonia in 100 g. of 2-n-butoxyethanol, after overnight agitation, was diluted with 15.0 g. of additional 2-n-butoxyethanol and gave a clear, homogeneous solution of a zinc ammine siliconate with an Si/Zn ratio of 2.0/1.0. Upon air drying, the solution gave a non-tacky coating which was firm, soft, water-repellent and water-insoluble, but swollen by toluene.
