Pvdf Metal Roof After Market Coatings

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 metal roof after market coatings.

As seen above in less than 10 years the pvdf fade resistance difference is clear. Pvdf coatings are especially resistant to solvents acids and have a very low density compared to similar fluoropolymers. Pvdf coatings can be applied to metal both before and after forming. 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.

The pvdf material contains 70 kynar resin which fades slower than other paint resins. 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. Factory applied pvdf fluoropolymer resin based coatings protect exposed metal and meet the highest performance standards for coatings on metal. 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.

Kynar pvdf coatings for steel aluminum and other metals also have a high dielectric strength excellent resistance to weathering elements in harsh environments. Its photo chemical resistance to ultraviolet light helps prevent breakdown from the sun s rays reducing heat generation and increasing energy efficient coolness. Factory applied pvdf based coatings are used globally and are specified by architects because of their weathering and durability performance. Kynar 500 coated metal roofing has many attractive features and benefits.

The roofing material is coated in zincalume and other metals to form a barrier that protects the base metal from corrosion. Pvdf polyvinylidene difluoride is a fluoropolymer resin that is the industry standard for the highest performing paints. Home metal roofing fade test pvdf finishes no other paint coating stands up to the sun s harsh uv rays like premium pvdf finishes. These requirements are outlined in the aama 2605 standard.
