TGF-331

THERMALLY CONDUCTIVE GAP FILLER

TGF-331

TGF-331 is a high temperature resistant, silicone liquid gap filler with very high thermal conductivity. It is a heavily filled system with heat conductive metal oxides. The material is a two-component, cured either at room or elevated temperature. The material is an excellent solution for interfacing fragile components.
