BERGQUIST® GAP FILLER TGF 4000

Known as Gap Filler 4000

Features and Benefits

This highly thermally-conductive liquid gap filler offers easy, precision dispensing, low stress assembly, and excellent low and high temperature, mechanical and chemical stability.
BERGQUIST GAP FILLER TGF 4000 is a 2-part, highly thermally conductive liquid gap filler. The mixed system will cure at room temperature, or faster with the addition of heat. It offers an extended working time to allow greater flexibility in the assembly process and, unlike cured thermal pad materials, a liquid offers infinite thickness variations with little or no stress to the sensitive components during assembly. You can also expect low level natural tack. Once cured, this product provides a soft, thermally conductive, form-in place elastomer ideal for fragile assemblies and filling unique and intricate air voids and gaps.
