QM 113



QM 113 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 where lower modulus and extremely tough rubber are required.  A variety of catalysts are offered with this material.


  • High tear strength
  • Low viscosity
  • Fast de-mold time
  • Low modulus
  • Useful temperature range -50 to 150C.

The standard catalyst for QM 113 is QM Cat Purple.  Additional catalysts include QM Cat Blue, QM Cat Red 3 QM Cat Clear, various thixotropic catalysts and QM Cat Clear FG for indirect food contact applications.*  Technical data sheets, and SDS are available in the Technical Library.

*Complies with FDA indirect food contact regulation CFR177.2600 only when used with QM Cat Clear FG.  Refer to QM Cat Clear FG data sheet for typical properties.


  • Molds for polyester, polyurethane and epoxy resin castings
  • Molds for technical articles and prototypes
  • Molds for small and large statues
