Claim Text:
1. A composition of matter comprising a fire retardant coating formulation in a form of a solvent or oil based paint having a fire retardant ingredient with a low-temperature intumescent agent, which intumesces at a temperature about 180° C. (356° F.) or below, which composition has a foundational fire retardant paint formulation that includes ingredients by weight as follows: Primary solvent of an aromatic organic liquid or blend thereof about from 20% to 50% Secondary solvent, which acts as a carbonific and is an organic polyol compatible and dispersible with the other ingredients about from 2% to 10% First film forming agent of a (vinyl aromatic)-acrylic polymer about from 5% to 15% Second film forming agent of another (vinyl aromatic)-acrylic polymer different from the first film forming agent, which enhances intumescence about from 1% to 5% Fire retardant wax of a halogenated paraffin about from 3% to 10% Nitrogenous spumific of a hydrogen-containing nitrogenous organic compound compatible and dispersible with the other ingredients about from 3% to 10% Carbonific of carbonaceous polyol compound about from 3% to 10% An ammonium polyphosphate about from 10% to 30% Generally inert filler of an inorganic opacifying agent,optionally with colorant about from 5% to 15%, to which foundational formulation is added the low-temperature intumescent agent.
