Compositions useful as a material for fuel lines comprising an intimate blend of:

Toughened, low permeability, solvent and salt resistant polyamide blends

No Bake foundry cores and molds for casting metals are prepared by using a binder comprising a polyol generally derived from alkoxylating an amine compound and a polyisocyanate. The binder is especially useful for casting non-ferrous metals, for example, the casting of aluminum, magnesium and other light weight metals. The cores and molds produced for casting aluminum and other light weight metals exhibit excellent shakeout while retaining other desirable core and mold properties. In addition the binders of this invention would have been observed to have an autocatalytic nature.

Process for casting lightweight metals

Process for no-bake foundry application utilizing polyurethanes based on

Disclosed is a resin-aggregate mixture comprising polyurethane resin, aggregate (sand), silane compounds, iron oxide and powdered thermoplastic resins. Flower pots from this composition are cured either with a tertiary amine, base, or metallic ion. The cured pots subsequently are baked at a temperature sufficient to fuse the thermoplastic resin to provide a pot having air permeability but resistance to the permeation of water.

Flower pot and method for making

Molding composition particularly suited for molding foundry cores and molds is obtained by mixing the components of a polyurethane resin with aggregate (sand), a silane, and iron oxide, molding the mixture to a desired shape and curing it.
