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.

Abstract: A cement composition contains 35-85% by weight of a cement, 3-15% by weight of a clay, 1-50% by weight of an aggregate and/or a fibrous material, and 0.2-5% by weight of a high efficiency retarder. A benefit of the present invention is that equipment used to apply cement compositions need not be cleaned every night when used on a construction site.
