Features and Benefits

BERGQUIST GAP FILLER TGF 1450, Two part, High performance, Thermally conductive liquid gap filling material

BERGQUIST® GAP FILLER TGF 1450 is a high performance thermally conductive liquid gap filling material which features high shear thinning characteristics for optimized consistency and control during dispensing. BERGQUIST GAP FILLER TGF 1450 features a low-density design which reduces final assembly weight. The mixed system will cure at room temperature and can be accelerated with the addition of heat. BERGQUIST GAP FILLER TGF 1450 offers infinite thickness variations with little or no stress to the sensitive components during or following assembly.
