  • Foundry binder with improved breakdown and improved thermal reclamation properties
    Patent number: 4615372
    Abstract: The addition of the metal drier to the phenolic urethane binder enhances the breakdown of the binder when the system is subjected to the elevated temperatures caused by pouring the molten metal into the mold and enhances the subsequent shake out of the sand from the cores and molds.
    Type: Grant

  • Binder for foundry process
    Patent number: 4148777
    Abstract: An improved binder composition for use in the foundry process comprises a mixture of low molecular weight essentially mononuclear methylolated phenols which are cured through a reaction with a polyisocyanate. In the preferred embodiment, a minor amount of polyether polyol, a mutual solvent and a catalyst, preferably an amine catalyst, is mixed with the phenolic component.

  • Improved foundry process and binder resin composition therefor
    Patent number: 4079031
    Abstract: An improved binder resin is disclosed for use in a foundry process, comprising a major proportion of a resole phenolic resin and a minor proportion of a polyether polyol and a mutual solvent therefor, wherein the polyol has an average molecular weight between about 200 and 5000 and a hydroxy functionality of about 2 to 4. The improved binder is used in the foundry process by mixing it with a polyisocyanate and preferably an amine catalyst.
