Abstract:
A silicone release coating composition comprises: (A) 100 weight parts of
an organopolysiloxane fluid having a viscosity at 25.degree. C. of 50 to
10,000 mPas and an alkenyl content of 0.10 to 3.0 wt %; (B) 0.5-40 weight
parts of a diorganopolysiloxane represented by the average structural
formula (1):
R.sup.c.sub.3SiO(R.sup.bR.sup.cSiO.sub.2/2).sub.n1(R.sup.c.sub.2SiO.sub.-
2/2).sub.n2SiR.sup.c.sub.3 (1)
wherein R.sup.b is an alkenyl group; R.sup.c is an alkyl group or a
phenyl group; n1 provides an alkenyl content of 0.05 to 0.80 wt. %; n2 is
at least 1; and n1+n2 provides this component with a viscosity at
25.degree. C. of 5,000 to 150,000 mPas; (C) an organohydrogenpolysiloxane
that has a viscosity at 25.degree. C. of 1 to 1,000 mPas, at least two
silicon-bonded hydrogen atoms in each molecule, and an alkyl group or a
phenyl group for its silicon-bonded organic groups; (D) a hydrosilylation
reaction catalyst in a catalytic amount; (E) a surfactant; (F) water; and
(G) an inhibitor.Claims:
