Abstract
Disclosed herein is a curing agent for epoxy resins that is comprised of the reaction product of an amine, an epoxy resin, and an elastomer-epoxy adduct. Additionally disclosed is a process comprising agitating a solution of an amine, an epoxy resin, and an elastomer-epoxy adduct as a dispersant at an elevated temperature in an organic medium.
Claims22
A curing agent for epoxy resins that is comprised of the reaction product of:
- (a) an amine, and
- (b) an epoxy resin, and
- (c) an elastomer-epoxy adduct;
- wherein the amount of adduct is from about 5 to 50% (w/w) based on the combined weights of the adduct and the amine.
A composition comprising an epoxy resin and a curing agent wherein the curing agent is the reaction product of:
- (a) an amine, and
- (b) an epoxy resin, and
- (c) an elastomer-epoxy adduct;
- wherein the amount of adduct is from about 5 to 5% (w/w) based on the combined weights of the adduct and the amine.
A device comprising an electronic component affixed to a substrate by an epoxy adhesive wherein the epoxy adhesive incorporates a curing agent that is comprised of the reaction product of:
- (a) an amine, and
- (b) an epoxy resin, and
- (c) an elastomer-epoxy adduct;
- wherein the amount of adduct is from about 5 to 5% (w/w) based on the combined weights of the adduct and the amine.
A fixed array ACF comprising gold particles dispersed in the adhesive film in a predetermined pattern, the adhesive film comprising an epoxy adhesive and a curing agent wherein the curing agent is the reaction product of an amine, an epoxy resin, and an elastomer-epoxy adduct.
