Fire resistant coating

摘要

A fire-resistant coating composition and method that can be applied to various poles and substrates so as to substantially reduce the likelihood of fire and/or heat damage. The first-resistant coating composition having a first component and a second component. The first component may comprise isocyanate and a thickening agent, and the second component may comprise a multifunctional polyol, preferably a tetrafunctional polyol, most preferably an amine-based tetrafunctional polyol, titanium dioxide, diol ether, expandable graphite particles, a flame retardant additive, at least one thickening agent, and a catalyst.

1. A fire-resistant coating composition comprising:
a first component comprising an isocyanate, at least a second component comprising an amine-based tetrafunctional polyol, at least one pigment, diol ether, expandable graphite particles, a flame retardant additive, a thickening agent and at least one catalyst, wherein the amine-based tetrafunctional polyol comprises from about 30 to about 60% by weight of the total second component, the pigment comprises from about 1 to about 10% by weight of the total second component, the diol ether comprises from about 5 to about 20% by weight of the total second component, the expandable graphite particles comprise from about 20 to about 50% by weight of the total second component, the flame retardant additive comprises from about 8 to about 30% by weight of the total second component, the thickening agent comprise from about 2 to about 5% by weight of the total second component, the at least one catalyst comprises a tin catalyst comprising from about 0.1% to about 4% by weight of the total second component and a polyurethane catalyst comprising from about 0.1 to about 2% by weight of the total second component.
