Title:
ORGANOPOLYSILOXANE COMPOSITION FOR USE IN RELEASE PAPER OR RELEASE FILM
Document Type and Number:
WIPO Patent Application WO/2021/187401
Kind Code:
A1
Abstract:
This organopolysiloxane composition for use in release paper or release film, said organopolysiloxane composition containing (A) an organopolysiloxane having two or more silicon atom-bonded alkenyl groups in each molecule, (B) an organohydrogen polysiloxane having two or more silicon atom-bonded hydrogen atoms (Si-H groups) on average in each molecule, (C) an organic peroxide and (D) a specific amount of a platinum group metal-based catalyst, is capable of undergoing an addition reaction with a smaller amount of the platinum group metal-based catalyst in comparison to the prior art, thereby being capable of forming a cured coating film which has a release strength equivalent to that of the prior art even in cases where a component that inhibits the catalytic activity of the platinum group metal-based catalyst is contained in the composition. In addition, this organopolysiloxane composition is capable of forming a cured coating film by means of an addition reaction even on a base material containing a catalyst poison component, on said base material conventional compositions being not able to be cured.
