PES coating has the advantages of good adhesion with iron,lead and other metals,and high surfacehardness.It can be used to make non-stick coating with corrosion resistance,radiation protection,low friction,good insulation,flame retardant,non-toxic,and the best adhesion with metal which iswidely used in kitchen appliances,household appliances,light industry hardware,industrial moldplastic machinery and other industries.Polima initiated water-soluble PES non-stick coating patented technology overcame the overreliance of traditional non-stick coating on PAI,greatly improving its alkali resistance. Meanwhile, ithas better coating hardness compared with traditional PAI coating and solves the problem that nonstick coating,whose binder is PAIcan’t be used to paint iron products.
