Conductive materials with electrical stability and good impact resistance for use in electronics devices |
摘要 |
A composition that comprises a) an admixing of at least one epoxy resin and aliphatic amine wherein the ratio of epoxy function group/amine is greater than 1; b) a conductive filler; c) one or more corrosion inhibitors, oxygen scavengers or both; d) imidazole as a curing agent/catalyst; and e) optionally other additives such as organic solvents, flow additives, adhesion promoters and rheology modifiers. The reaction of epoxy and aliphatic amine with excess epoxy functionality results in a flexible resin with remaining active epoxy groups. The compositions exhibit improved electrical stability and impact resistance over other conductive adhesive compositions that do not comprise the admixture.
