Patent number: 5626656Abstract: A release agent for green sand mold forming contains a hydrocarbon oil as the main lubrication component. The release agent contains a surface active agent as a dispersant and an anion surface active agent and/or a strong basic amine as a wettability improving agent as essential components besides the hydrocarbon oil. The release agent is used in a form of oil-in-water type emulsion by diluting it with water. Since it is possible to dilute the release agent with water, the release agent occupies less capacity during storage and transportation, and since the release agent can increase the water to the hydrocarbon oil ratio of the composition at application, it contributes to improvements in resource saving and safety against fire.Type: GrantFiled: May 22, 1996Date of Patent: May 6, 1997Assignee: Tetra Co., Ltd.Inventors: Kazumitsu Kondo, Keiichi Ito
