Coating & Adhesive Resins


By developing saturated polyesters, Evonik has played an important role in influencing and extending the possible applications of precoated metals. 

These coating raw materials are suitable for the production of coatings with very good adhesion offering an optimum of flexibility and formability together with an excellent surface hardness. For this reason, lacquers based on DYNAPOL® have proved particularly suitable for stampable and deep drawable coatings. 

A wide range of products is available for various requirements of the paint and coating industry. DYNAPOL® polyester resins are mainly used for stoving enamels in combination with amino resins. Special properties, such as chemical resistance, weathering resistance and flexibility, can be improved by using blocked polyisocyanate resins. Stoving enamels based on high-molecular weight copolyesters show particularly good mechanical properties. Medium-molecular weight polyester resins containing more hydroxyl groups are suitable for the manufacture of stoving enamels with good reactivity and high solids content. In combination with high-molecular weight copolyesters the quality of films can be optimized. 

Depending on the technical requirements and the method of processing, DYNAPOL® grades can also be used to manufacture industrial coatings.
