The present invention relates to polyol blends containing a polyol and a polyphenol alkoxylate, i.e. an alkoxylated polyphenol, and coatings prepared from these blends. The polyol blends have the advantage of a low residual polyphenol content and have desirable viscosity characteristics without the need for diluents or solvents which could result in unwanted VOC emissions. In another aspect of theinvention, polyester polyol is prepared using polyphenol alkoxylate. Coatings prepared using these polyol compositions have improved salt spray corrosion resistance, along with a variety of other excellent coating performance properties. Also, the polyol used herein can contain a significant recycle and bio-renewable content, making these blends and coatings sustainable alternatives to petroleumbased polyol products. 本公开涉及含有多元醇和多酚烷氧基化物(即烷氧基化多酚)的多元醇共混物，以及由这些共混物制备的涂料。所述多元醇共混物具有残留多元酚含量低的优点，并且具有理想的粘度特性而无需稀释剂或溶剂，这些稀释剂或溶剂可能导致有害的VOC排放。在本发明的另一方面，使用多酚烷氧基化物制备聚酯多元醇。使用这些多元醇组合物制备的涂料具有改善的耐盐雾腐蚀性，以及其它各种优异的涂料性能特性。同时，本文使用的多元醇可以含有重要的循环
