PURPOSE:To provide a resin compsn. for jig and tool which gives a cured article free from surface or inside voids even when mixed and cured without being deaerated under a reduced pressure by compounding an epoxy resin with a curative for the resin, microballoons, and a sepcific silicone surfactant. CONSTITUTION:The compsn. is prepd. by compounding a liq. epoxy resin of a phenol ether or glycidyl ether type with a curative for the resin, 5-58vol.% microballoons with a specific gravity of 0.15-0.6 and particle diameters of 5-300mum, and 0.01-5wt.% silicone surfactant comprising a polyoxyalkylsiloxane- polyoxyalkylene block copolymer. |
