Aluminum triphosphate-containing intumescence flame-retarding coatings

The effect of aluminium triphosphate (ATP) on the flame resistance of intumescent flame retardant coatings (IFRCs) has been explored, with an aliphatic waterborne polyurethane (AWP) as the binder.

The quantitative analysis on the pyrolysis kinetics of an ATP-containing AWP-based coating was also investigated, and it was determined that a dosage of 2 wt% of ATP in the AWP-based coating produced an enhanced flame resistance, evidenced by the fire growth index decreasing from 0.49 to 0.34 kW/m2/s.

The study was published in Progress in Organic Coatings, Volume 147, October 2020.
