Alcohol-Sensitive Epoxy Formulations for Temporary or Repairable Embedment
HARRY DIAMOND LABS ADELPHI MD
Pagination or Media Count:
Repairable embedding epoxy formulations have been developed that are alcohol sensitive and hence can be readily removed with an alcohol without damage to the embedded components. The alcohol sensitivity is greatly enhanced with polyN-vinyl-2-pyrrolidone as filler. Some basic thermal, electrical, and mechanical properties of the cured epoxies were found to be satisfactory. Being inherently more hydrophilic than the regular epoxy, the materials are not intended for the continuous use in an environment of high humidity. For occasional exposures, a low filler level or an application of a protective thin coating of a regular epoxy is advisable.
