Abstract
When tris(2-hydroxyethyl) isocyanurate and a long chain amine are employed together in intumescent flame retardant compositions, tris(2-hydroxyethyl) isocyanurate bloom is substantially reduced or even eliminated, and yet the flame retardant effectiveness of the tris(2-hydroxyethyl) isocyanurate is substantially retained.
