CHT Group QSil 12 QSI Quantum Silicones Clear Low Viscosity for Potting Material
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	QSil 12 is a clear, transparent, low viscosity, two-component, liquid silicone material which cures at room temperature and is primarily intended for potting applications. This material is typically mixed at a ratio of 100:5. Once mixed, the material is self-leveling and will have a useful worklife of approximately two hours. The material will be fully cured after 24 - 48 hours at room temperature. This material can also be vulcanized at elevated temperatures (up to 70°C) to increase the cure speed. Key Features: Low viscosity Variable cure speed, with mild heat Transparency Room temperature cure Good adhesion with use of a primer Part of the Amber Chemical Group. Data provided by manufacturer. Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
