Blair, N. D. published the artcileNovel fire retardant intumescent coatings, Application In Synthesis of 866-23-9, the publication is Journal of Paint Technology (1972), 44(573), 75-82, database is CAplus.
The efficiency of 21 P compounds in epoxy coatings varied in series acids > phosphates .sim. phosphites >> phosphonates. The weight loss, char area, and char volume of epoxy coatings containing tri-Ph phosphite [101-02-0] and tri-Me phosphate [512-56-1] were generally minimized while the intumescence maximized as the concentration of amine catalyst, P compound, and film thickness were increased over a wide range. A combination of a high melting insoluble chlorocarbon and phosphoryltrianilide [5326-10-3] were used to prepare fire retardant pigmented alkyd and chlorinated alkyd paints with excellent water and scrub resistance. The fire retardant properties of epoxy coatings containing (PhO)3P were unchanged after immersion in water at 50.deg. for 24 hr.
