Patent number: 7011763Abstract: A foam concentrate or fire fighting composition for extinguishing and/or retarding fires is provided that meets UL162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents. The concentrate is used to form the fire fighting composition when mixed with water. The concentrate or fire fighting composition includes a high molecular weight fluoropolymer and water and may have a fluorine content wherein less than about 0.008% fluorine by weight of the fire fighting composition is provided from any fluorochemical surfactant. Further, the composition may meet the UL162, Class B performance criteria without forming a stable seal on cyclohexane.Type: GrantFiled: August 6, 2002Date of Patent: March 14, 2006Assignee: Chemguard IncorporatedInventor: Kirtland P. Clark

Patent number: 7005082Abstract: A foam concentrate provides a fire-fighting composition when mixed with water so that the fire-fighting composition does not form a stable seal on cyclohexane and meets UL 162, Class B performance criteria for at least one of AFFF agents and fluoroprotein (FP) agents without requiring organic fluorine. The concentrate is formed from water and a high molecular weight acidic polymer (HMWAP) and a coordinating salt.Type: GrantFiled: June 20, 2003Date of Patent: February 28, 2006Assignee: Chemguard IncorporatedInventor: Kirtland P.
