Title:
SILICONE RUBBER COMPOSITION FOR TEMPLATING MATRIX AND TEMPLATING MATRIX
Document Type and Number:
WIPO Patent Application WO/2009/048162
Kind Code:
A1
Abstract:
It is intended to provide a silicone rubber composition for a templating matrix
which has an excellent mold release property, gives less stain to replicated
products, and is excellent in defoaming of a material before curing. More particularly,
it is a silicone rubber composition for a templating matrix containing (A) a polyorganosiloxane
having 2 or more alkenyl groups binding to a silicon atom in one molecule and a viscosity
at 25ºC of 500,000 to 1,000,000 centipoise (100 parts by weight); (B) a polyorganohydrogensiloxane
having 3 or more hydrogen atoms binding to a silicon atom in one molecule (an amount
such that the number of hydrogen atoms binding to a silicon atom per alkenyl group
binding to a silicon atom in the component (A) is 0.4 to 4); (C) a platinum compound
(1 to 200 ppm by weight in terms of platinum atom relative to the component (A));
and (D) a polydimethylsiloxane having an alkoxy group with 1 to 3 carbon atoms
binding to a silicon atom at its molecular terminal and an average degree of polymerization
of 5 to 500 (0.1 to 10 parts by weight).
