CHT Group QM 122 QSI Quantum Silicones 22 Durometer Condensation Cured Moldmaking Material
Categories:	Polymer; Thermoset; Silicone
Material Notes:	QM 122 is a two-component, room temperature condensation cure silicone material. The cured rubber is flexible with excellent mechanical and physical properties in addition to good shelf-life stability. This material is an excellent choice for the molding of intricate patterns which involve deep undercuts and where dimensional stability becomes important while maintaining fairly low modulus. A variety of catalysts are offered with this material. Complies with FDA indirect food contact regulation CFR 177.2600 when used with Cat Clear FG. Refer to Cat Clear FG data sheet for specific properties. Key Features: Low viscosity Excellent tear resistance Fast demold time Moderately high durometer with a moderately low modulus Main Applications: Molds for small statues, large statues and monument restoration Molds for polyester, polyurethane and epoxy resin castings Molds for prototypes Picture frame and architectural molds Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
