Categories:	Polymer; Thermoset; Silicone; Silicone Foam
Material Notes:	Description: The product is a two-part, room temperature platinum cure, self blowing silicone foam designed for liquid dispense. The product is ideal for potting in applications where lightweight and thermal protection are required. 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 cured product provides electrical insulation and physical shock resistance of components and enables environmental protection. Key Features Low viscosity Fast room temperature cure Low smoke, flame, and toxicity upon combustion Primerless chemical adhesion at room temperature to many substrates Key Applications: Lightweight potting and encapsulation EV battery modules PCB staking Insulation Information provided by CHT Group
