Patent ID: 8519024

Claim:
An intumescent fireproofing composition, comprising a formulation that includes: a. a resin; b. a coalescent; and c. glass fibers of a predetermined size; wherein the resin is a vinyl acetate copolymer; wherein the coalescent exhibits a boiling point of greater than 240° C., the coalescent is effective to substantially reduce or eliminate the potential for volatile organic compound (VOC) release, and the coalescent is selected from a group consisting of 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate) and bis(2-ethylhexanoate) triethylene glycol; wherein the VOC is an organic compound exhibiting a boiling point greater than 250° C.; wherein the predetermined size of the glass fibers is a length of between 0.2 mm and 3 mm; and wherein the intumescent fireproofing composition delivers effective fireproofing and hangability performance, the hangability performance being defined by an absence of sliding or sagging of the intumescent fireproofing composition, wherein sliding is a measure of movement of the intumescent fireproofing composition from an application position on a coated area to a position below the coated area due to gravity, and wherein sagging is a measure of an increase in coating thickness from an applied thickness of the intumescent fireproofing composition to a final thickness defined by at least a two-fold increase in thickness from top to bottom of the coated area due to gravity.
