CHT Group QM 130T 30 Shore A, Translucent, Condensation Cure Moldmaking Material
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Product Description: QM 130T is a two-component, translucent, room temperature, condensation cure, silicone material. When catalyzed with QM Cat Clear Thixo 2 the resulting material is extremely thixotropic. QM 130T is also available for non-thixotropic, flowable applications when catalyzed with QM Cat Clear. The cured rubber has excellent properties and good shelf life stability. Key Features: High tear strength High thixotropy (if desired) Fast demold time Excellent dimensional stability Main Applications: Molds for polyester, polyurethane and epoxy resin castings Designed specifically for vacuum bag applications Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
