Description

QSil 216 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
