| TRA-CAST 3145 is a medium viscosity thermally conductive epoxy adhesive that is used for staking and setting transistors, diodes, resistors, integrated circuits and other heat-sensitive components in printed circuit electronic applications. This two-part compound develops strong, durable high-impact bonds at room temperature which improve heat transfer while maintaining electrical insulation. TRA-CAST 3145 bonds readily to itself, and to metals, silica, steatite, alumina sapphire and other ceramics, glass, plastics and many other materials, because its coefficient of thermal expansion provides a good match for those materials over a fairly wide temperature range. Fully cured TRA-CAST 3145 provides excellent resistance to salt solutions, mild acids and alkalis, many other chemicals including petroleum solvents, lubricating oils, and alcohol. This adhesive complies with the requirements of NASA Outgassing Specification when tested according to ASTM E-595-90. Information provided by Tra-Con Inc. |
