摘要： This invention relates to a composition comprising a semisolid epoxy resin containing a curative dispersed therein. The curative has a particle size such that at least 90% of the particles have a size below 25 pm at ambient temperature of 21° C., wherein the composition further comprises a diluent containing a particulate filler. The composition is used as matrix in prepregs. The use of the diluent increases peel strength of the composition when brought into contact with metal or wood substrate.
