ETERNACOLL® UH200 is a solvent-free solid aliphatic polycarbonate diol. Provides high chemical resistance, excellent hydrolytic stability, high thermal stability as well as high mechanical properties. Exhibits higher gloss, enhanced hydrolysis resistance, improved scratch as well as abrasion resistance. Offers better adhesion to metal even after weathering and better corrosion resistance by replacing the blend of a classical polyol by this polycarbonate diol. Polyurethanes produced from ETERNACOLL® UH200 are superior to those based on polyether diol as well as polyester diol.
