Pvdf Metal Roof After Market Coatings

Pvdf is a revolutionary coating system that consists of pvdf resin acrylic resin and ceramic pigments giving your panels more vibrant fade resistant durability.

Pvdf metal roof after market coatings.

Coatings are applied in factory in coil coating applications for metal roofs garage doors and wall panels or spray applied to formed aluminum extrusions on curtain walls aluminum window and door framing gutters soffits and sunshades. These requirements are outlined in the aama 2605 standard. The pvdf material contains 70 kynar resin which fades slower than other paint resins. Solvent based polyvinylidene fluoride pvdf coatings have been the hallmark in performance for metal roof and wall panels for over 50 years and are the product of choice for architects specifying a premium exterior coating system for buildings.

Cool metal roofs coated with kynar 500 pvdf based resin can reduce energy consumption by up to 40 as part of a total system design as reported by the lawrence berkeley national laboratory. Pvdf coatings are especially resistant to solvents acids and have a very low density compared to similar fluoropolymers. Kynar pvdf resin based coatings offer long lasting performance in demanding architectural coating applications. Its photo chemical resistance to ultraviolet light helps prevent breakdown from the sun s rays reducing heat generation and increasing energy efficient coolness.

Pvdf coatings can be applied to metal both before and after forming. Kynar pvdf coatings for steel aluminum and other metals also have a high dielectric strength excellent resistance to weathering elements in harsh environments. Fluropon exterior coatings from sherwin williams offer field proven high performance for metal roofing panels and more fluropon containing a 70 percent pvdf proprietary resin system meets or exceeds the american society for testing and materials stringent standards the american architectural manufacturers association s aama 2605 high performance exterior specification. Kynar polyvinylidene fluoride pvdf resins are used by licensed industrial paint manufacturers in formulating hardy long lasting coatings.

Factory applied pvdf based coatings are used globally and are specified by architects because of their weathering and durability performance. Pvdf polyvinylidene difluoride is a fluoropolymer resin that is the industry standard for the highest performing paints. As seen above in less than 10 years the pvdf fade resistance difference is clear. The roofing material is coated in zincalume and other metals to form a barrier that protects the base metal from corrosion.
