Polyester polyol chemistry has been used extensively as a binder option in high performance industrial coatings applications for decades. Limitations of traditional polyester technology, such as weathering and chemical resistance have restricted its use to a co-binder due to the high level of performance requirements associated with these markets. Translating the use of a specialty monomer from copolyesters for thermoplastic applications, chemists at Eastman have evaluated the effectiveness of a unique glycol molecule as a building block in copolyester coatings resins targeted for use in automotive coatings, metal packaging applications for food cans, and industrial applications like the agricultural and construction segment. Proven to enhance the hydrolytic stability and offer a balance of flexibility and hardness, the specialty polyol is enabling distinctive binder properties to address ever-changing global coatings needs. Fulfilling performance targets across very diverse fitness for use criterion, this paper capitalizes on the versatility of the specialty polyol platform of resins. Through performance comparisons to next best alternative technologies, the improved durability will highlight the advantage of this next generation of polyol chemistry.
