Patent ID: 8163819

Claim:
A thermally curable adhesive composition for attaching a micro-fluid ejection head to a device, the adhesive composition comprising: from 55.0 to 88.0 percent by weight, based on the overall adhesive composition, of a flexible epoxy resin; from greater than 0 to 3.5 percent by weight, based on the overall adhesive composition, of an amine adduct; from 7.4 to 11.0 percent by weight, based on the overall adhesive composition, of an imidazole catalyst thermal curative agent; and from 0.6 to 1.0 percent by weight, based on the overall adhesive composition, of an epoxy silane coupling agent, wherein the adhesive composition has shear modulus of less than about 10 MPa at 25° C. and glass transition temperature of less than about 65° C.
