QM 122



QM 122 is a two-component, room temperature, condensation cure silicone material.  The cured rubber is flexible with excellent mechanical and physical properties in addition to good shelf-life stability.  This material is an excellent choice for the molding of intricate patterns which involve deep undercuts and where dimensional stability becomes important while maintaining fairly low modulus.  A variety of catalysts are offered with this material.


  • Low viscosity
  • Excellent tear resistance
  • Fast de-mold time
  • Moderately high durometer with a moderately low modulus


The standard catalyst for QM 122 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 MSDS 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 prototypes
  • Picture frame and architectural molds
  • Molds for small and large statues and monument restoration
