Features and Benefits

BERGQUIST GAP FILLER TGF 4000, Thermally Conductive, Two-part, High Performance, Liquid, Gap Filler Material
BERGQUIST® GAP FILLER TGF 4000 is a two-part, high performance, thermally conductive, liquid gap filling material. The mixed material will cure at room temperature and can be accelerated with the addition of heat. BERGQUIST GAP FILLER TGF 4000 offers an extended working time to allow greater flexibility in the customer’s assembly process. Liquid dispensed thermal materials offer infinite thickness variations and impart little to no stress on sensitive components during assembly. BERGQUIST GAP FILLER TGF 4000 exhibits low level natural tack characteristics and is intended for use in applications where a strong structural bond is not required. As cured, BERGQUIST GAP FILLER TGF 4000 provides a soft, thermally conductive, form-in-place elastomer that is ideal for fragile assemblies or for filling unique and intricate air voids and gaps.
