Abstract
A varnish for protecting painted surfaces comprises by weight (a) 30 to 60% of at least one siloxane having an average R/Si ratio of 1.2 to 1.6 and containing an average of 0.5 to 2.5% of Si-bonded hydroxyl groups, (b) 1 to 25% of a monomeric or polymeric methyl or ethyl silicate, (c) 1 to 20% of at least one organic solvent-soluble titanic or zirconic ester or condensation polymer thereof, (d) 0 to 20% of an organic solvent-soluble organic zinc salt, and (e) at least 15% of a solvent for all the above. The siloxane may contain methyl, ethyl, butyl or phenyl radicals and may also contain -Si.Si- and -Si.CH2.Sigroups. Suitable esters (c) are those derived from alcohols containing from 2 to 18 C atoms, e.g. isopropyl, butyl and octyl titanates. In typical examples: (1) methyl polysilicate and zinc 2-ethylhexoate in white spirit were added to a mixture of a mineral spirit solution of a methyl siloxane resin having a ratio CH3/Si=1.5 and a Si-bonded OH content of 0.3% (by wt.) and a toluene solution of another methyl siloxane resin having a ratio CH3/Si=1.3 and a Si-bonded OH content of 3.2%, and the resulting solution was heated to 80 DEG C. with the subsequent addition of a butyl acetate solution of a butyl polytitanate and further heating until a clear liquid was obtained; (3) the composition was prepared as in (1) except that the siloxane resins were replaced by a methyl phenyl siloxane resin having a ratio C6H5 + CH3/Si=1.5, C6H5/Si=0.3 and a Si-bonded OH content of 0.5% and a methyl siloxane resin having a ratio CH3/Si=1.5, a Si-bonded OH content of 1% and -Si.Sigroups, as described in Specification 736,971.
