Title: Innovations of Raymond G. Spain
Introduction
Raymond G. Spain is a notable inventor based in Huntington Beach, California. He has made significant contributions to the field of materials science, particularly in fire retardant technologies and the splicing of carbonized materials. With a total of nine patents to his name, Spain's work reflects a commitment to innovation and safety in various applications.
Latest Patents
One of Spain's latest patents is a fire retardant coating for combustible substrates. This aqueous base coating system primarily consists of an emulsion of an extensible halogenated polymer and water-insoluble fillers. The coating releases non-combustible gases when heated and is designed for exterior application to combustible substrates. Once dried, the coating is no longer redispersible by water and adheres strongly to materials such as wood. This innovation provides a substantial degree of fire resistance, requiring only 0.1 to 0.3 pounds of dried coating per square foot of the exposed combustible substrate to effectively resist ignition and flame spread.
Another significant patent involves a method and resin solution for splicing carbonized polyacrylonitrile (PAN) tows. In this method, the tows are cut square and coated at the ends with a resin solution. The coated ends are then joined, heated to cure the resin, and pinched to compact the splice. The resin solution comprises a mixture of solid and liquid acrylic polymers, a solid epoxy resin, and a solvent, showcasing Spain's innovative approach to enhancing material properties.
