CHT Group QM 140T 40 Shore A, Translucent, Condensation Cure Moldmaking Material
Categories: Polymer; Thermoset; Silicone

Material Notes: Product Description: QM 140T is a two-component, translucent, room temperature, condensation cure, silicone material. This material was specifically designed for vacuum bagging applications. When catalyzed with QM Cat Clear Thixo 2 the resulting material is extremely thixotropic. QM 140T is also available for non-thixotropic, flowable, applications when catalyzed with QM Cat Clear. The cured rubber has excellent properties and good shelf life stability.

Key Features:

  • High tear strength
  • High thixotropy (if desired)
  • Fast demold time
  • Excellent dimensional stability
Main Applications:
  • Molds for polyester, polyurethane and epoxy resin castings
  • Designed specifically for vacuum bag applications

Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
