<p>Improved air-drying primer compositions for solid substrates adapted for top coating with curable colloidal silica filled thermoset silicone resins comprise an acrylic ester dissolved in a mixture of 2-ethoxyethanol and 4-hydroxy-4-methyl-2-pentanone. In comparison with prior art primer compositions, there is no need for heat and/or ultraviolet curing of the present compositions.</p> |
