CHT Group QSil 216 QSI Quantum Silicones Transparent Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	QSil 216 is a two-part, clear, liquid silicone 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: Convenient 10:1 mixing ratio for use in automatic dispensing equipment or hand mixing Contains no solvents Non-yellowing catalyst system Chemical composition provides hydrolytic stability and reversion resistance Part of the Amber Chemical Group. Data provided by manufacturer Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
