Kynar Painted Corrugated Metal Roofing

colored roofs

Kynar Painted Finish for Corrugated Metal roofing panels weathers exceptionally well. PVDF is a specialty plastic material in the fluoropolymer family; it is used generally in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. Compared to other fluoropolymers, it has an easier melt process because of its relatively low melting point.

A fine powder grade, KYNAR 500 PVDF is used as the principal ingredient of high-end paints for metals. These PVDF paints have extremely good gloss and color retention, and they are in use on many prominent buildings around the world, e.g. the Petronas Towers in Malaysia and Taipei 101 in Taiwan, as well as on commercial and residential metal roofs. PPG Industries, Inc. is a well-known supplier of such PVDF-containing coatings.

What is PVDF

It is a resin used in Architectural coatings that has exceptional weathering characteristics. PVDF stands for polyvinylidene fluoride. It is also known as "Kynar", or more properly, ®Kynar 500. ®Kynar 500 is a registered trade mark of Arkema Inc. North America, Inc. To quote Arkema: "Kynar® polyvinylidene fluoride (PVDF) resin is one of the most stable and pure of all commercial resins. It resists strong acids, solvents, and reducing agents and is used in several industries, including metal roofing, electrical and electronic manufacturing, chemical processing, pulp and paper, and transportation." The word Kynar is being used in everyday conversation the way the trade name "Kleenex" is used synonymous with tissues.
