CHT Group QM 2225 25 Shore A, Condensation Cure Moldmaking Material
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Product Description: QM 2225 is a two-component, room temperature, condensation cure silicone material. The cured rubber has excellent mechanical properties and good shelf-life stability. This material is an excellent choice for the molding of intricate patterns, skin molding and applications where higher durometer, dimensional stability and extremely tough rubber are required. A variety of catalysts are offered with this material. Key Features: Low specific gravity High tear strength Low viscosity Long work-life Fast demold time Excellent flowability Main Applications: Molds for large and small statues Molds for polyester, polyurethane and epoxy resin castings Molds for technical articles and prototypes Molds for furniture and picture frame replication Molds for GFRC pre-cast Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
