CHT Group QM 2325 25 Shore A, Condensation Cure Moldmaking Material
Categories: Polymer; Thermoset; Silicone

Material Notes: Product Description: QM 2325 is a two-component, room temperature, condensation cure, silicone material. The cured rubber is flexible and has 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 a fairly low modulus.

Key Features:

  • Low viscosity
  • Excellent tear resistance
  • Fast demold time
  • Moderately high durometer with a moderately low modulus
Main Applications:
  • Molds for large statues, small statues and monument restoration
  • Molds for polyester, polyurethane and epoxy resin castings
  • Molds for technical articles and prototypes
  • Molds for architecture and picture frames

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