Résumé : |
Coatings on large surfaces like bus, railway coaches often encounter several challenges such as narrow application window, longer recoat interval, overspray merging problem, drying behavior etc. which results into poor finish, gloss and DOI (Distinctness of Image). This phenomenon becomes more adverse in tropical countries like India where temperature and humidity are on extreme side especially during the time of application. Covestro has the most innovative low viscous high solid Polyisocyanate technology to address this issue. These products not only meet the performance requirements but also achieve superior appearance. |
