Abstract
PURPOSE:To obtain a surrounding instrument having high hardness, which does not require heat treatment after molding, by mixing unsaturated epoxy resin, unsaturated polyester and a copolymerizing cross-linking agent and compounding a fibriform base material. CONSTITUTION:The long chains of the unsaturated epoxy resin and the unsaturated polyester resin are cross-linked by the copolymerizing cross-linking agent, the adhesive strength with metals of the epoxy resin is added to the polyester resin, and the heat-shrinkage of the polyester resin is minimized by the fibriform base material (3mum-5mm.) while strength at the time of heating is increased. A reaction is completed instantaneously because the composition is cured by a copolymerization reaction, its hardness is extremely high and its adhesive strength is strong, and the excellent surrounding instrument is obtained. Cost can be reduced because expansive resin such as epoxy resin is contained only by one part.
