Abstract: An epoxy resin composition having a first epoxy resin component containing an oxazolidone; a second epoxy resin component; a latent hardener comprising dicyandiamide particles having a particle distribution in which at least 35% of the dicyandiamide particles have a particle size of less than 2 microns; and an epoxy soluble latent catalyst is provided. It has been found that the combination of the epoxy components, a latent hardener having dicyandiamide particles in which at least 35% of the dicyandiamide particles have a particle size of less than 2 microns, and an epoxy soluble latent catalyst provides an epoxy resin composition that provides a more homogeneous infusion of the resin into a fibrous material for forming a prepreg. As a result, faster cure of the epoxy resin composition is obtained, which in turn, reduces the mold cycle time for preparing molded articles and parts.

Abstract: A method for mounting a metal substrate to a first substrate comprises a metal substrate having a plurality of through holes in at least a portion of the metal substrate and the application of a one part moisture curing adhesive on the adherend first surface, adherend metal surface or both. The first substrate and metal substrate are contacted interposing the adhesive between the adherend first surface and the adherend metal surface such that a portion of the length of at least one through hole is penetrated by the adhesive. The adhesive is cured in the presence of moisture.
