CHT QSil 212 Transparent Liquid Silicone Elastomer
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Description: The product is a transparent and colorless silicone formulation and is ideal for optical applications. The viscosity profile enables excellent flow around components and is excellent for potting complex parts. The chemical composition results in a cured product that is hydrolytically stable as well as reversion resistant. The silicone elastomer provides electrical insulation and physical shock resistance of components and enables environmental protection. Key Features UL listed in file No. E205830 Low linear shrinkage Non-yellowing catalyst system Chemical adhesion with use of primer Application: LED encapsulation Information provided by CHT Group
