February 9, 2012


QM 140 is a two-component, room temperature, condensation cure silicone material.  The cured rubber has excellent mechanical properties and good shelf-life stability.  This material is an excellent choice for the molding of intricate patterns, skin molding and applications where high durometer, dimensional stability and extremely tough rubber are required.


  • High tear strength
  • Low viscosity
  • Fast demold time
  • Excellent dimensional stability


The standard catalyst for QM 140 is QM Cat 140.  Additional catalysts include QM Cat 140 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 technical articles and prototypes
  • Molds for furniture and picture frame replication
