CHT Group QSil 960 55 Shore A, Condensation Cure for Potting Applications
Categories: Polymer; Thermoset; Silicone

Material Notes: Product Description: QSil 960 is a red, high temperature, self-leveling, two-component, condensation cure, silicone material primarily intended for potting applications. The two applicable catalysts are 0.5% DBT by weight and 10% Deep Section Catalyst by weight which gives a self leveling material with a work life of approximately 60 minutes. The material will be fully cured after 24 – 36 hours at room temperature. The 0.5% catalyst level can be increased or decreased to obtain desired cure speed.

Key Features:

  • Self-leveling
  • Variable cure speed
  • Excellent thermal stability
  • Retention of elastomeric properties within the temperature range of - 115°C – 260°C

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