Patent ID: 7851254

Claim:
A method for adhesively attaching a first substrate to a second substrate, said method comprising: a. applying a composition to one or both of said first substrate or said second substrate, wherein the composition is a b-stage curable composition comprising: a. a solid component heat curable at a first temperature; b. a liquid component, which is either heat curable at a second temperature or curable upon exposure to radiation in the electromagnetic spectrum; and c. a heat cure catalyst for the solid curable component; b. exposing the composition-applied substrate to conditions favorable to effect cure of the liquid curable component thereof, thereby forming a b-staged curable film; c. exposing the b-staged curable film of b. to a temperature in the range of 90° C. and 160° C. sufficient to melt the solid curable component thereof; d. adjoining said first substrate with said second substrate to form an assembly wherein said first substrate and said second substrate are separated by the composition applied in a.; and e. exposing the curable film of c. to a temperature condition in the range of 150° C. and 200° C. to cure the melted, solid curable component.
