Super Thermal Conductive Epoxy Electrically Insulating Heatsink 195, 1.5gm

Description

Technical Product Bulletin
SUPER 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 which improve heat
transfer while maintaining electrical insulation.
AA-SUPERTHERM 195
bonds readily to itself and to metals, silica, 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
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 Material Safety Data Sheet, (MSDS).
HOW TO USE:
1)
Carefully clean and dry all surfaces to be bonded.
2)
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.
3)
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.
4)
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.
