8327GF25 Liquid Thermal Gap Filler 8327GF25 is a two-component, flame retardant, thermally conductive silicone gap filler. It is a smooth, non-sagging paste that easily conforms to the complex shapes of any interface design. The cured product creates a thermal path that efficiently dissipates heat from electronic devices. It retains its softness after cure which maximizes stress relief during thermal cycling. 8327GF25 can be used as a liquid alternative for prefabricated solid thermal pads. If higher thermal conductivity is desired, use 8327GF41.
