END USE DESCRIPTION

FEATURES

POLYDURE® features:

POLYDURE® laundry finishes are intended to be factory applied, to metal substrates according to Akzo Nobel Product Data Sheets, over primer, by the coil coating method only. This process efficiently and economically applies primer and system topside coatings according to exact film thickness specifications across the entire panel width. In this process, coatings are applied to specified metal substrates that have been thoroughly cleaned and chemically prepared in accordance with manufacturer's instructions to optimize adhesion, forming and other designed-in performance characteristics. Topside primer and backside coatings must be baked and cured in factory ovens at metal temperatures ranging from 400-480°F. Color, gloss and other properties are routinely monitored during the quality control process. The coil coating process is highly efficient with nearly 100% transfer efficiency of paint to metal coils. This application process collects and destroys almost all volatile organic content (VOC's) usually associated to any painting process.
