Patent number: 4452927Abstract: Resin coated sand for foundry shell molding operations is provided which eliminates the cracking of the molds at the time of pouring. In conventional phenolic bonded sand molds, the abrupt thermal expansion caused by the pouring of the molten metal into the mold causes the mold to crack. The resin coated sand, in this invention, is composed of foundry sand or aggregates coated with a phenolic resin which has incorporated therein, a polyethylene glycol of high molecular weight. This improved coated sand eliminates cracking at pouring and does not impair the shake-out property of the molds.Type: GrantFiled: January 5, 1983Date of Patent: June 5, 1984Assignee: Sumitomo Durez Company, Ltd.Inventors: Noriaki Matsushima, Yukio Saeki, Yukio Tokunaga
