The synergistic effect of a nitrogen and phosphorus containing reactive monomer on the flame retardancy of photocured epoxy acrylate based coatings was investigated.The incorporation of allyl phosphinic amide into an epoxy acrylate decreased the gel contents and the double bond conversions. Mechanical properties were significantly affected from the degree of cure. Tensile strength of the coatings decreased as the amount of the monofunctional allyl phosphinic amide was increased. Flame retardancy of the epoxy acrylate was increased with the addition of allyl phosphinic amide but decreased with the addition of octamercaptopropyl polyhedral oligomeric silsesquioxane.
