摘要:
Resinous composition comprising: (A) 100 weight parts of (R2SiO2/2)w(RSiO3/2)x(SiO4/2)y(O1/2R1)z wherein R is selected from the group consisting of monovalent hydrocarbon groups having 1 to 10 carbon atoms, R1 is selected from the group consisting of the hydrogen atom and saturated hydrocarbon groups having from 1 to 6 carbon atoms, w is a number from 0 to 0.2, x is a number from 0.4 to 0.9, y is a number from 0.1 to 0.6, z is a number from 0.1 to 0.5, and (w+x+y)=1; (B) 20 to 150 weight parts of an alcohol-based solvent; (C) 100 to 1000 weight parts of a solvent selected from the group consisting of hydrocarbon-based solvents and polydimethylsiloxanes described by the formula Me3SiO(Me2SiO)nSiMe3, wherein Me is the methyl group and n has a value of 0 or 1; (D) 1 to 100 weight parts of a coupling agent selected from the group consisting of alkoxysilanes and silane coupling agents; (E) 0.1 to 20 weight parts of a condensation catalyst, and (F) 0.1 to 20 weight parts of a polyoxyalkylene-modified silicone.
