What is halogenated unsaturated polyester resin


Halogenated unsaturated polyester resin is a kind of chlorinated unsaturated polyester synthesized from chlorinic anhydride (HET) as saturated dibasic acid (anhydride).

Chlorinated unsaturated polyester resin has been used as a resin with excellent self extinguishing properties.But in recent years, studies have shown that unsaturated polyester resin chlorinated also has fairly good corrosion resistance, its corrosion resistance in some medium and bisphenol A unsaturated polyester resin and vinyl resin basic quite, and in some cases, such as wet chlorine in the corrosion resistance is superior to vinyl resin and bisphenol A unsaturated polyester resin.

Hot wet chlorine reacts with unsaturated polyester resin after contact to produce chlorinated unsaturated polyester resin or "chlorine cream".The "chlorine cream" produced by bisphenol A unsaturated polyester resin and vinyl ester resin is soft. Wet chlorine can penetrate further through the "chlorine cream" layer (corrosion), but the "chlorine cream" produced by chlorinated unsaturated polyester is hard and can prevent further (corrosion) penetration of wet chlorine.
