2. Applications in Flame Retardant Coatings
(1) Ammonium Polyphosphate (APP) is a top-grade flame retardant coating material that can be used in fiberglass, engineering plastics such as PE, PP, PU, polyester, and nylon.
(2) When 15-20% APP is added to adhesive and sealing agents, it exhibits excellent fire resistance.
(3) APP is a suitable non-halogenated flame retardant for PU.
(4) It is also applicable to fiber-based materials such as paper and wood products, as well as hot solidifying resins like epoxy and unsaturated resins.
