BERGQUIST® GAP FILLER TGF 1450, 400 ml Dual cartridge



BERGQUIST® GAP FILLER TGF 1450 is a 1.4 W/m-K thermally conductive, ultra-conforming silicone-based liquid gap filler (2-part). It provides a high level of control due to its high shear thinning characteristics, and dries with a low density to reduce final assembly weight. The mixed system remains ultra-conforming with excellent wet-out for near zero interface stress, and offers infinite thickness variations without adding stress to the sensitive components during or following assembly. This product is curable at room temperature, and the cure rate can be accelerated by applying heat.
