ABSTRACT:
An improved conductive adhesive and capacitor formed using the improved conductive adhesive. The conductive adhesive has:60-95 wt % conductor;5-40 wt % resin; wherein the resin has:55-98.9 wt % monomer defined by the formula:wherein: R is an aliphatic group of 1 to 10 carbons;R1is an aliphatic group of 1 to 10 carbons;R2is an alkyl, alkyl ether, aryl ether, silane or silicone; andwherein R and R1, R and R2or R1and R2may be taken together to form a cyclic alkyl or aryl group;0.1-15 wt % catalyst;1-30 wt % accelerant defined by the formula:wherein R3is an alkyl or substituted alkyl of 1-10 carbons; andR4is an alkyl or substituted alkyl of 1-10 carbons with the proviso that at least one of R3and R4is substituted with a OR5wherein R5is selected from hydrogen, alkyl and aryl; and0-15 wt % filler.
