Water Resistant Heat Sink Compound is offered in paste form and is heavily filled with heat conductive metallic oxides in a silicone base. The Heat Sink Compound is used for maintaining a positive heat-sink seal that improves heat transfer from the electrical or electronic component to the heat sink or chassis. The Heat Sink Compound is water resistant and capable of high thermal conductivity. Water Resistant Heat Sink Compound is used as a non-flammable coating for fly back transformer connections in television chassis and similar applications.
