摘要：
A release silicone emulsion composition comprising:(A) 100 parts by weight of a specific organovinylpolysiloxane;(B) from 1 to 50 parts by weight of a specific organohydrogenpolysiloxane;(C) from 0.5 part to 5 parts by weight of a platinum catalyst having a viscosity of 10 cSt or less at 25.degree. C.;(D) from 1.5 to 15 parts by weight of a nonionic emulsifying agent having an average HLB of from 10 to 20, pH of 6.5 or less and an ionic conductivity of 30 .mu..OMEGA..sup.-1 cm.sup.-1 or less; and(E) water.This composition has good pot life and curability. The cured film had good release properties and residual adhesive properties of adhesives.
