3.5W/mK Silicone Thermally Conductive Potting Two Parts Fire
Resistant LED Lighting Potting
TIS™680-35AB is a two-component, high thermal conductive, low
temperature cured, long pot life , fire resistant Silica
encapsulant glue. lt is design for potting of capacitors and
electrical devices.Their flexibility and elasticity make them
suited to the coating of the very uneven surfaces. Heat can
transmit to the metal housing or dissipation plate from the
separate elements or even the entire PCB, which in effect enhances
the efficiency and lfe-time of the heat-generating electronic
components.
