Technical Product Bulletin
THERMALLY CONDUCTIVE ELECTRICALLY INSULATING COMPOUND
PRODUCT DESCRIPTION
AA-SUPERTHERM 195 is a two-component, thermally conductive epoxy system recommended for staking transistors, diodes, resistors, integrated circuits, and other heat-sensitive components to printed circuit boards.
This adhesive develops strong, durable, high-impact bonds at room temperature, improving heat transfer while maintaining electrical insulation.
AA-SUPERTHERM 195 bonds readily to itself and to metals, silica, alumina, sapphire, other ceramics, glass, plastics, and many other materials, as its coefficient of thermal expansion provides a good match for these materials over a wide temperature range.
Fully cured AA-SUPERTHERM 195 provides excellent resistance to salt solutions, mild acids and alkalis, and 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.

GENERAL INFORMATION
For safe handling information on this product, consult the Safety Data Sheet, (SDS).
HOW TO USE
- Carefully clean and dry all surfaces to be bonded.
- Apply AA-SUPERTHERM 195 completely mixed adhesive to the prepared surfaces, and gently press these surfaces together. Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
- Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use.
- Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best results.
AVAILABILITY
This epoxy can be supplied in various different packages.
