  • SMOKE-SUPPRESSING ADDITIVE FOR POLYURETHANE-FORMING BINDER SYSTEM
    Publication number: 20240033809
    Abstract: A sand additive for use in a “no bake” foundry mix composition having a polyurethane-based binder system reduces the amount of smoke emitted when molds and cores formed from the composition are exposed to molten metal, as compared to when the sand additive is not used. The sand additive comprises yellow iron oxide having the chemical formula Fe(OH)3. It can also comprise at least one of red iron oxide, black iron oxide and wüstite. In such cases, the yellow iron oxide accounts for about 10 to about 40 weight percent of the combined weight of the yellow iron oxide, red iron oxide, black iron oxide and wüstite, and preferably, about 20 to about 30 weight percent of the combined weight of the yellow iron oxide, red iron oxide, black iron oxide and wüstite.

  • HALLOYSITE CLAY AS SMOKE-REDUCING ADDITIVE FOR POLYURETHANE-FORMING BINDER SYSTEM
    Publication number: 20230249244
    Abstract: An amount of a halloysite clay, used as an additive in a foundry mix composition having a polyurethane-based binder system, reduces the amount of smoke emitted when molds and cores formed from the composition are exposed to molten metal, as compared to when the halloysite clay is not used.
