Material Notes:

QM 245 is a two component, room temperature addition cure silicone material. The cured rubber has excellent mechanical properties and good shelf-life stability. This material is a good choice for the molding of furniture, picture frames and architectural materials. QM 245 is exceptionally good where highly detailed parts and mold flexibility are required. Complies with FDA indirect food contact regulation CFR 177.2600 (Red Catalyst only is CFR 177.2600 compliant)Key Features: Excellent tear resistance Casting resin resistance Fast demold time Good mold flexibilityMain Applications: Molds for architectural replication Molds for polyester, polyurethane and epoxy resin castings Molds for technical articles and prototype Molds for furniture and picture frame replication Part of the Amber Chemical Group.
