Material Notes:
QM 107 is a two component, room temperature condensation cure silicone material. The cured rubber is very soft, has excellent mechanical properties and good shelf-life stability. This material is an excellent choice for the molding of intricate patterns, skin molding or for applications which demand a tough rubber. The hardness of QM 118 is the midpoint of the QM100 series and therefore offers excellent physical properties. A variety of catalysts are offered with this material.  Key Features:Low ViscosityExcellent physical propertiesFast demold timeMain Applications: Molds for small statues, large statues and monument restoration Molds for polyester, polyurethane and epoxy resin castings Molds for prototypes Part of the Amber Chemical Group.
