AA-Bond 2153 Thermally Conductive, Electrically Insulating Compound, 2 Part, Thixtropic, 100gm kit

AA-BOND 2153 is a thixotropic (smooth paste) thermal conductive epoxy system that passes the NASA Outgassing Specification. It is used for staking transistors, diodes, resistors, integrated circuits and other heat sensitive components to printed circuit boards. AA-BOND 2153 is two parts adhesive develops strong, durable, high impact bonds at room temperature which improve heat transfer while maintaining electrical insulation. AA-BOND 2153 bonds to itself and to metals, silica, alumina, others ceramics, glass, plastics and many other materials. AA-BOND 2153 provides excellent resistance to salt solutions, mild acids and alkalis, and many other chemicals.
