  • Publication number: 20200263042
    Abstract: 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.

  • Patent number: 9725615
    Abstract: The present disclosure relates to coating compositions, kits, and methods of applying the same, for use with fireproofing materials. The coating compositions are effective to control the drying rate and shrinkage of fireproofing materials. The coating compositions are also able to be applied to fireproofing materials shortly after these materials have been applied to a substrate.

  • Publication number: 20130331489
    Abstract: 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.
