Master Bond adhesives
CHT Group QSil 220 Transparent, Liquid Silicone Rubber
Categories: Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)

Material Notes: Product Description: QSil 220 is a two-part, clear, liquid silicone which cures at elevated temperatures. It has a low viscosity which allows for ease of flow around complex parts, providing electrical insulation and shock resistance. The chemical composition provides hydrolytic and reversion resistance. This material also has excellent, primerless adhesion to most substrates.

Key Features:

  • Convenient 10:1 mixing ratio for use in automatic dispensing equipment or hand mixing
  • Contains no solvents
  • Non-yellowing catalyst system
  • Heat cure required to obtain full properties and adhesion

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