ABSTRACT:
An adhesive material is provided which is particularly suitable for potting a sensing element within a container. The adhesive material is characterized by mechanical and physical properties which enable the adhesive material to maintain its adhesive and structural integrity under intense thermal cycling conditions, so as to exclude foreign elements from the sensing element when potted within a container with the potting material. The adhesive material can be formulated so as to be sufficiently adherent for use with containers formed from materials such as polybutylene terephthalate, polyethylene terephthalate, and E-coated steel, by including additions of a flexibilized polyol/polyepoxide epoxy novolac in an amount of up to about 15 parts by weight.
