The POLYDURE® family of coatings is formulated from a variety of proprietary, low cost and special-use polyester resins. It is designed to contribute color to metal coils that are later fabricated into a variety of prefabricated metal products for economy exterior and multiple interior uses. Some examples are: building liner panels, garage and entry doors, print-coats, office furniture, certain metal HVAC and home appliance components, lighting fixtures, table skirts and other miscellaneous fabricated metal products. A wide array of POLYDURE® topcoat colors is available. Compatible Akzo Nobel primers are available as required by the metal substrate and ultimate prepainted product end use.
POLYDURE® polyester systems 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 POLYDURE® colors 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 pretreated in accordance with manufacturer's instructions to optimize adhesion, forming and weathering characteristics. POLYDURE® coatings and primers must be baked and cured in factory ovens at temperatures ranging from 400°-480°F. Color, gloss, hardness, flexibility and adhesion are only a few of the coating performance characteristics monitored in the quality control process. The coil coating process is highly efficient with nearly 100% transfer efficiency to the metal coils. This process collects and destroys almost all volatile organic content (VOC's) usually associated to any painting process.
Test methods established by ASTM (American Society for Testing and Materials).
Physical Properties of the Coating:
| Total film thickness ranges from 0.65-0.90 mils (16-23 microns); which includes 0.20 mils (5 microns) minimum, primer where specified; Without primer, 0.80 mils (20 microns), minimum film thickness. | |
| Typically between 25-80% on a 60° meter. Lower gloss by special request. | |
| 500 hours: Pass - actual performance varies with pretreatment, substrate and requirement. | |

Complete building panel test reports are available upon request. Consult Technical Product Information pages for specific fabricated metal end uses or call Akzo Nobel Sales and Marketing.
POLYDURE® colors are made with high quality pigments in a wide range of colors. ISO 9001 certified Akzo Nobel manufacturing methods at our Columbus Headquarters facility uniformly distribute pigments into selected proprietary polyester resins with proven, performance in the specified painted metal application to resist changes in color and general appearance and, to preserve film integrity and prolong coating service life.
In construction product applications, proper maintenance will contribute to maximum installed life performance. Contact Akzo Nobel and ask for a copy of our "Care and Maintenance Guide" for recommended methods and procedures. Colormatched air-dry coatings for post construction touch-up and scratch repair, as mentioned in the "Care and Maintenance Guide," are available for POLYDURE® coatings through your prepainted metal products fabricator.
Contact your fabricator/manufacturer for installed cost estimates. POLYDURE® performance warranties are available for specific applications. Contact Akzo Nobel Coatings Marketing and Sales department or your metal system supplier.
