QM 118

February 8, 2012



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.


  • Low viscosity
  • Excellent physical properties
  • Fast demold time



  • Molds for polyester, polyurethane and epoxy resin castings
  • Molds for prototypes
  • Molds for large and small statues and monument restoration


The standard catalyst for QM 118 is QM Cat Purple.  Additional catalysts include QM Cat Blue, QM Cat Red 3 QM Cat Clear, and various thixotropic catalysts.
