  • Method for forming sand cores and molds
    Patent number: 4448234
    Abstract: A hydrogen peroxide system or composition for use in resin polymerization comprises a mixture of a major part of concentrated (70%) hydrogen peroxide admixed with minor amounts of phosphoric acid, a halo-substituted acid, such as hydrochloric acid, fluoboric acid or hydrofluoric acid, and sodium perborate. The peroxide composition is characterized by its storage stability, resistance to detonation, zero flammability, ease of handling and improved catalytic properties in the polymerization of certain resins. This hydrogen peroxide composition is compatible for use with a variety of organic peroxides which have been used for resin condensation polymerization and may be used in conjunction therewith. This hydrogen peroxide composition may be safely mixed with resins and resin prepolymers on the sand prior to use.
