Features and Benefits

BERGQUIST GAP FILLER TGF 3600, Thermally Conductive, Two-part, Liquid, Gap Filling Material
BERGQUIST® GAP FILLER TGF 3600 is the technology leader in thermally conductive, liquid gap filling materials, featuring ultra-high thermal performance and superior softness. The material is a two-component liquid gap filling material, cured at either room or elevated temperature. Prior to curing, the material maintains good thixotropic characteristics as well as low viscosity. The result is a gel-like liquid material designed to fill air gaps and voids yet flow when acted upon by an external force (e.g. dispensing or assembly process). The material is an excellent solution for interfacing fragile components with high topography and/or stack-up tolerances to a universal heat sink or housing. Once cured, it remains a low modulus elastomer designed to assist in relieving CTE stresses during thermal cycling yet maintain enough modulus to prevent pump-out from the interface. BERGQUIST GAP FILLER TGF 3600 will lightly adhere to surfaces, thus improving surface area contact. BERGQUIST GAP FILLER TGF 3600 is not designed to be a structural adhesive.
