CHT TufGel 3350 Silicone Gel
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Description: This is one of a family of soft, adherent, silicone elastomeric gels designed for the encapsulation and protection of electronic components. It is a low viscosity, 2-component system that is readily mixed in a 1:1 ratio. It is used to provide protection from vibration, thermal or mechanical shock and protection from water and many environmental contaminants. It has excellent dielectric properties. Key Features Low modulus minimizes stress on parts and components Fast room temperature cure Potted or encapsulated assemblies can be repaired with modest effort Primerless chemical adhesion at room temperature to many substrates Information provided by CHT Group
