Patent number: 8882898Abstract: The present invention is directed to an emulsified release agent for use in manufacturing of wood products from wood fibers or chips with pMDI adhesives, where the application process for the release agent would normally agitate the release agent. The emulsified release agent is simple to manufacture, has good stability and storage, provides effective release between the wood product and the metal surfaces, allows for production of wood products from wood fibers or chips at high temperature, without causing excessive press buildup and improves the physical properties of the wood product and shortens press time. The emulsified release agent composition for use with a pMDI adhesive comprises an emulsified mixture of: (a) an alkali metal salt of a fatty acid having 8-18 carbon atoms, and (b) an alkali metal salt of a phosphate ester having 6-22 carbon atoms and having an HLB number of 4 or less.Type: GrantFiled: November 29, 2010Date of Patent: November 11, 2014Assignee: Guardian Chemicals, Inc.Inventors: Jiping Fang, Stewart A.
