Abstract:
1. Epoxy resin composition consisting of: (a) 30 to 94.5% by weight, based on the amount of components (a), (b) and (c) of an epoxy resin liquid at room temperature having on average more than one 1,2-epoxide group in the molecule; (b) a hardener-accelerator system consisting of a polyoxyalkylenediamine type hardener or a combination of a polyoxyalkylenediamine type hardener and a non-polyoxyalkyleneamine type hardener selected from a cycloaliphatic amine and an aromatic amine; (c) an impact modifier consisting of an S-B-M block copolymer, an M-B-M block copolymer, a combination of an S-B-M block copolymer and at least one second polymer, or a combination of an M-B-M block copolymer and at least one second polymer, wherein the at least one second polymer is selected from the group consisting of an S-B block copolymer, an amine terminated butadiene acrylonitrile copolymer, a carboxyl terminated butadiene acrylonitrile, and combinations thereof; and (d) optional additives selected from the group consisting of a degassing agent, fillers, pigments, dyes, flame retardant substances, antistatics, adhesion promoters, flow control agents, antioxidants, light stabilizers, fibers and combinations thereof.
