20. A method of forming an epoxy/elastomer adduct, the method comprising:
-
providing an epoxy component, wherein the epoxy component is provided as a phenolic resin including at least one of a bisphenol-A epichlorohydrin ether polymer or a solid bishpenol-A epoxy resin;
providing an elastomer, the elastomer being a butyl nitrile rubber;
mixing at least about 70 parts by weight of the epoxy component with at least about 15 parts by weight of the the elastomer in the presence of a catalyst such that the epoxy component at least slightly reacts with the elastomer to form the adduct, the catalyst being selected from a phosphine and an iodide. - View Dependent Claims (21, 22, 23)
