CHT Group QM 260 QSI Quantum Silicones 60 Durometer Addition Cure Moldmaking Material
Categories:	Polymer; Thermoset; Silicone
Material Notes:	QM 260 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 260 is exceptionally good where high durometer and dimensional stability are required. Key Features: High Durometer Casting resin resistance Fast demold time Excellent dimensional stability Main Applications: Molds for architectural replication Molds for polyester, epoxy resin casting, and rigid or foam polyurethane Molds for technical articles and prototype Molds for furniture and picture frame replication Candy and other food molds Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
