Publication number: 20200263042Abstract: The present disclosure relates to intumescent fireproofing coatings and methods to apply these coatings. In particular, the disclosure relates to an intumescent composition having a first epoxy resin layer containing a first intumescent material and a reinforcement mesh, wherein the reinforcement mesh has an adhesive applied to only one surface thereof. After the reinforcement mesh/adhesive is applied to the first epoxy resin layer, a second epoxy resin layer containing a second intumescent material is generally applied thereon.Type: ApplicationFiled: May 8, 2020Publication date: August 20, 2020Applicant: United States Mineral Products CompanyInventor: Robert Paul Kreh

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
