<p>SILICONE-MODIFIED EPOXY RESINS HAVING IMPROVED IMPACT RESISTANCE This invention relates to a dispersion of a functional silicone modifier in a curable epoxy resin wherein emulsification of said silicone is aided by a siloxanepolyoxyalkylene copolymer. The silicone modifier comprises an alpha,omega functional polydimethylsiloxane having carboxyl, amine or epoxide endgroups. A method of using the dispersion to improve the impact resistance of the resin, when the latter is cured, is described.</p> |
