Abstract
A method of imparting corrosion-inhibition to a primer by incorporating in the primer from 0.1% to 65% by weight of calcium-silico-zirconate. The resulting primer provides a high level of corrosion-resistance when applied to metal substrates.
Claims2
A method of imparting corrosion-inhibition to a primer by formulating into the primer from 0.1% to 65% by weight of calcium-silico-zirconate of the formula xCaO.SiO.sub.2.ZrO.sub.2, wherein x is from 2.75 to 3, based on the weight of the primer.
A corrosion-inhibitive primer formulation consisting essentially of an organic film-forming vehicle, diluent and pigment, wherein calcium-silico-zirconate of the formula xCaO.SiO.sub.2.ZrO.sub.2, wherein x is from 2.75 to 3, is present in an amount from 0.1% to 65% by weight, based on the weight of the primer formulation.
