Abstract
A fire retardant, intumescent, curable composition for use in composite materials has as its principal ingredients a curable resin system and a fire retardant combination of a polyhydroxy compound, a polyphosphate, a nitrogen-containing compound and a polyacrylate monomer. Significant reduction of the flame spread index is achieved.
