Use for:
Potting or encapsulation of power supply / transformer assemblies that require good thermal dissipation

 TSE3331 silicone rubber compound is a two component, heat curing liquid silicone for potting and encapsulation where flammability and/or thermal conductivity is of concern. It provides excellent flame retardant properpties (UL94 V-0) and very stable dielectric properties over a broad range of operating temperatures. In addition, TSE3331 silicone rubber compound also offers superior thermal conductivity properties when compared to other conventional silicone encapsulants. This product must be cured in a well ventilated oven.
