Abstract: Unsaturated polyester resin(UPR )coatings is one of early developed coating varieties. The reasons that UPR is used as the film forming resin of coating are not only for its excellent properties of coating film, but also lower cost. Therefore UPR coatings are widely used in coatings industry. This article has reviewed the research progress in existing various unsaturated polyester resin coatings. Unsaturated polyester resin coatings could be divided into various types, such as air-drying, antifouling, flame-retardant, anticorrosion, electric insulation and low (zero )volatile organic compound(VOC )coatings. The features and latest development of various unsaturated polyester resin coatings were reported respectively. The mechanisms of coatings were briefly described, and the future development trend and research direction of UPR coatings were presented.
