CHT Group QSil 217 Transparent, Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Product Description: QSil 217 is a two-part, clear, liquid silicone that 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. The chemical composition provides hydrolytic and reversion resistance. Key Features: Convenient 1:1 mixing ratio for use in automatic dispensing equipment or hand mixing Contains no solvents Non-yellowing catalyst system Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
