Abstract

See full text

An epoxy-based resin system composition includes a latent functionality for polymer adhesion improvement. The composition may be used to produce an overcoat layer and/or protection layer in an anti-sulfur resistor (ASR). In some embodiments, the composition include epoxy-based resin(s), hardener(s) and, optionally, blowing agent(s) and/or filler(s). An epoxide functionality of one or more of the epoxy-based resin(s) and a reactive functionality of one or more of the hardener(s) react with each other at a first temperature. The latent functionality, which does not react at the first temperature, is contained in at least one of the epoxy-based resin(s), hardener(s) and filler(s) and reacts in response to another stimulus (e.g., UV light/initiator and/or a second temperature greater than the first temperature) to enhance chemical bonding. Optionally, voids created via etching and/or the blowing agent(s) may be used to enhance mechanical bonding, alone, or in combination with filler(s) exposed in the voids.
