一般特征
Ionic/non-ionic polycarbonate ester polyurethane dispersion.
Bayhydrol® XP 2637 is a polyurethane dispersion which can be used to formulate coatings that harden at room temperature or baking coatings. It allows coating of a wide variety of substrates ranging from hard ones to flexible ones such as leather, textiles, plastics and metals.
Coatings formulated with Bayhydrol® XP 2637 exhibit high scratch resistance and lightfastness. Other benefits of Bayhydrol® XP 2637 are good aging stability and very good hydrolysis resistance.
