CHT Group QSil 214 Specialty Silicone Coating
Categories: Polymer; Thermoset; Silicone

Material Notes: Product Description: QSil 214 is a low viscosity, two-component, addition cure, silicone elastomer which will cure at room temperature or at elevated temperatures. It has a low viscosity, which allows for ease of flow around complex parts, providing electrical insulation and shock resistance.

Key Features:

  • Medium viscosity
  • Fast room temperature cure
  • Low linear shrinkage
  • Transparent

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