Abstract:
A thermosetting, thermally-expandable molded body comprising:(a) at least one solid reactive resin selected from the group consisting of (i) solid polyglycidyl ethers of polyphenols, polyalcohols and diamines, (ii) solid polyglycidyl esters of polycarboxylic acids, and mixtures thereof, (b) at least one liquid reactive resin selected from the group consisting of (i) liquid polyglycidyl ethers of polyphenols, polyalcohols and diamines, (ii) liquid polyglycidyl esters of polycarboxylic acids, and mixtures thereof, (c) at least one reactive resin conferring flexibility selected from the group consisting of rubber-modified epoxy resins, polyurethane-modified epoxy resins, adducts of amino-terminated polyoxyalkylenes and polyepoxides, adducts of polymeric fatty acids and epichlorohydrin, glycidol, or diglycidyl ethers of bisphenol A, adducts of polyether polyols with epoxy resins, polymercaptan-modified epoxy resins, polysulfide-modified epoxy resins, and mixtures thereof, (d) at least one additive selected from the group consisting of latent hardeners and accelerators, and (e) at least one expanding agent.
