NOTE ** Elf Atochem North America, Inc., manufactures KYNAR 500(R) polyvinylidene fluoride (PVDF) as the major vehicle (base resin) for licensing to leading liquid coating formulators. Dispersion coatings based on a minimum of 70 percent by weight of KYNAR 500(R) resin are formulated by these licensees and subsequently factory-applied and oven-baked as final finishes for aluminum, galvanized steel, or aluminized steel. A list of licensees may be obtained from Elf Atochem North America, Inc.
NOTE ** KYNAR 500(R) resin-based coatings are more stable and offer superior weathering performance. When compared to competitive coating systems (plastisol, urethane, silicone polyester, and acrylic), they change less in color, gloss, and chalk, and exhibit superior corrosion resistance, flexibility, stain resistance, and overall durability. KYNAR 500(R) resin-based finishes meet or exceed the physical test performance criteria of the American Architectural Manufacturers Association (AAMA Specification 605.2) for high-performance organic coatings on architectural extrusions and panels and the more demanding Architectural Spray Coaters ASCA '96 Specification for Superior Performance of Organic Coatings on Architectural Aluminum, Curtainwall, Extrusions, and Miscellaneous Aluminum Components.
