Product description:
Epoxy resin modified APP-II(CF-APP204,CF-APP204S) is a flame retardant based on phosphorus /nitrogen synergism, free formaldehyde, manufactured from CF-APP201/201S with epoxy resin treated according to own method.
Its solubility in water is very low and has less influence in polymers.CF-APP204/204S is quite suitable in epoxy resin, polyurethane ,and textile coating system.
