| Résumé : |
Polyurethane polymers in coating applications are well known for providing outstanding properties such as adhesion, corrosion resistance and weatherability among others, generally at a premium cost. New developments will be reviewed which adress performance, environmental and cost issues related to polyurethane based systems in an attempt to increase the viability and market penetration versus alternative technology. These new developments include "Vorastar" polymers, cost competitive weatherable systems and water based dispersions. Finally, it will be demonstrated that polyurethane dispersions can be used successfully, where excellent performance justifies the comparatively high costs. |
