Title:
RELEASE AGENT COMPOSITION AND RELEASE FILM FOR CERAMIC GREEN SHEET MOLD
Document Type and Number:
WIPO Patent Application WO/2012/132681
Kind Code:
A1
Abstract:
A release agent composition contains: a polyorganosiloxane (A) which has at least two alkenyl groups in a molecule, and has an aryl group on each side chain of at least one silicon atom in a siloxane skeleton; and a polyorganosiloxane (B) which has an alkenyl group at only both ends in a molecule, but does not have an aryl group. The solid component ratio of the polyorganosiloxane (A) with respect to the total amount of the polyorganosiloxane (A) and the polyorganosiloxane (B) is 40 to 98 percent by mass, and the mass average molecular weight of the polyorganosiloxane (A) is 100000 to 800000. The release agent composition is excellent for ceramic slurry coatability, and is excellent for ceramic green sheet releasability.
