Abstract:
A solid inter-laminar adhesive composition comprising:(A) a liquid epoxy resin; (B) a polyfunctional epoxy resin having a softening point higher than a lamination temperature of the adhesive and with two or more epoxy groups per epoxy resin molecule; (C) a latent epoxy curing agent initiating a reaction at a temperature higher than the lamination temperature; (D) a binder polymer with a weight average molecular weight with a range of 5,000 to 100,000 in an amount of from 5 to 50% by weight of the composition; and (E) from 10 to 55% by weight of the composition of a liquid resin other than the liquid epoxy resin (A) or an organic solvent or a combination thereof.
