Title:
SILICONE RUBBER MOLD MAKING-UP MATERIAL
Document Type and Number:
Japanese Patent JP2013234282
Kind Code:
A
Abstract:

To provide a silicone rubber mold making-up material capable of forming a silicone rubber mold having transparency suitable for fabrication of mold parting and having excellent mold making-up durability.

By blending a linear organopolysiloxane containing 4 to 16 mol% of a phenyl group, a three-dimensional network-structured organopolysiloxane containing 4 to 16 mol% of a phenyl group, an organohydrogenpolysiloxane containing a phenyl group of ≥4 mol% of the total amount of a silicon atom-bonded hydrogen atom and a silicon atom-bonded organic group, a silica micropowder and a platinum-based compound in predetermined blend amounts, a cured material can be obtained which is excellent in transparency relevant to visibility of a master in mold parting, and which allows to increase the number of times of mold making-up when duplicate products are manufactured using an urethane resin or an epoxy resin.
