New Developments Provide Architects With Superior Paint Systems

Developed by Asahi Glass in 1982, LUMIFLON® is the first solvent -soluble fluoropolymer for coatings that can be cured at room temperature, making it highly suitable for field application. Since that time, fluororesin paints based on LUMIFLON® raw materials have been produced by many manufacturers around the world and applied to more than 150,000 architectural structures worldwide.

The primary benefits of LUMIFLON® are its superior durability, weatherability and longevity. Because of the strength of LUMIFLON’s® Carbon-Fluorine (C-F) bonds, and its unique chemical structure, the weatherability can be extended for years. In turn, the fluoropolymer’s durability prevents corrosion from water, oxygen and chloride. With its superior weatherability, LUMIFLON® ensures a longer life on building exteriors and facades, resulting in less need for repainting and a substantial decrease in life cycle costs compared to other coatings on the market today.

In addition to its superior durability, LUMIFLON® also offers architects the ability to use brighter colors and higher gloss than Kynar® PVDF systems. Kynar® dispersions are milky and cloudy, reducing the maximum gloss to about 40. LUMIFLON® resins are clear, meaning that LUMIFLON® resins have no matting effect, offering gloss values as high as 90. That means LUMIFLON® offers architects the option to specify brighter and more varied and a broad range of gloss, from matte to high gloss. In addition, LUMIFLON® coatings can be either heat cured or cured at ambient temperature, offering fabricators a choice between shop application or application in the field. A perfect match between coil coating colors and field applied coating colors can be obtained. LUMIFLON® fluoropolymer coatings can also be used to repair Kynar® coatings in the field.

LUMIFLON® has been used internationally on building exteriors and facades for over 25 years. Architects are learning that LUMIFLON® coatings can be used on steel, aluminum, fiberglass, concrete and polycarbonate for 30 years without fading, providing weathering and corrosion protection. Some recent American project sites include the new Experience Music Project museum in Seattle, the Hartford Children’s Hospital in Connecticut, the NASCAR Café in Orlando, the Silicon Graphics building in California, the Escape Roller Coaster at Universal Studios in Orlando and the Clinton Presidential Library in Arkansas.
