Abstract: Nitroaromatic amine-based intumescent coatings which offer improved thermal protection to a substrate by reducing the backface temperature rise have been developed. The intumescent monomer agent is 4,4 prime-dinitrosulfanilide. This agent has an intumescent temperature of 220 deg C, compared with 300 deg C for the ammonium salt of 1,4-nitroaniline-2-sulfonic acid and offers a twelve-fold reduction in water solubility over this compound. On the basis of differential thermal analysis and screening tests, a chlorinated polyolifin epoxy-reactive butadiene acrylonitrile rubber blend was selected as a flame quenching binder.
