QUA QM 118

QM 118 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 QM 100 series and therefore offers excellent physical properties.   A variety of catalysts are offered with this material.
