Publication number: 20130331489Abstract: Water-based intumescent fireproofing formulations are provided that exhibit excellent fireproofing properties while simultaneously significantly reducing and/or eliminating the potential for VOC release and exhibiting excellent hangability properties. The intumescent fireproofing formulation includes a coalescent that significantly reduces and/or eliminates the potential for VOC release and fiber constituents, e.g., fibers of greater than 0.2 mm in length. Exemplary coalescents have a boiling point of at least 180° C. and include bis(2-ethylhexanoate)triethyleneglycol, 2,2,4-trimethyl-1,3-pentanediolmono(2-methylproponate) and 2,2,4-trimethyl-1,3-pentanedioldi(2-methylpropanoate). Intumescent fireproofing formulations are also provided that include clay to further improve performance.Type: ApplicationFiled: August 19, 2013Publication date: December 12, 2013Applicant: United States Mineral Products Company dba Isolatek InternationalInventor: Robert Paul Kreh

Patent number: 4121958Abstract: This invention pertains to a thermal insulating laminate which comprises a rigid, closed cell foam core, suitably a polyurethane foam core, and a porous fabric or paper sheet adhered to at least one surface of the core. The porous sheet layer is impregnated with polymeric material having the same composition as the core during the lamination process. This invention also pertains to the modification in which a metallic foil is bonded to the porous sheet by means of a flame-resistant and low smoke-producing adhesive. Preferably, there is also a network of glass fiber strands between the sheet and the foil. The laminate can be used as insulating board under built-up roofs, for wall sheathing in building construction, and all other normal applications for rigid polyurethane insulation. The laminate incorporating the foil-glass layers can also be utilized in situations where additional dimensional stability and additional flame resistance are required.Type: GrantFiled: September 21, 1977Date of Patent: October 24, 1978Assignee: United States Mineral Products CompanyInventor: Lamonte R.

Patent number: 4019938Abstract: Insulation board comprising a urethane foam core sandwiched between a thin flexible membrane and a thicker inflexible panel is made by dispensing foam forming materials onto a moving continuous sheet of the thin flexible membrane and depositing individual panel segments onto the foam as it expands. The manufacturing apparatus includes a conveyor press for transporting the flexible membrane past a foam dispensing device and means for consecutively depositing the individual panel segments onto the expanding foam. The panel depositing means comprise a suction apparatus for suspending the panel over the foam and a friction drive mechanism for simultaneously impelling a leading end of the panel against a trailing end of an immediately preceding panel to prevent the formation of gaps between consecutive panel segments. The resultant laminate is then passed through the conveyor press that acts as a forming and curing zone for the laminate which is thereafter cut to size at a cutting station.Type: GrantFiled: January 14, 1976Date of Patent: April 26, 1977Assignee: United States Mineral Products CompanyInventor: Harry Forrester
