Patent 7566409 was granted and assigned to Mainstream Engineering Corporation on July, 2009 by the United States Patent and Trademark Office.
Chlorofluorocarbon replacement solvents include a main component (first solvent) and a property-modification component (second solvent). The resulting solvent mixtures meet or exceed the solvency, flammability, and compatibility requirements for CFC's while providing similar or improved environmental and toxicological properties. These solvent mixtures can be used in conjunction with refrigeration or heat pumps, electronics, implantable prosthetic devices, oxygen systems, and optical equipment.
