Architectural coating is an important part of both construction and daily life. Whether skyscrapers, sheds, homes, hangars, or port buildings, construction both old and new is enhanced, beautified, and protected by coatings. These coatings need to stand up to the daily wear of everything Mother Nature can throw at them, and PVDF coating comes out at the end as the architectural coating with the best weatherability. PVDF coating (short for polyvinylidene fluoride coating) is known for its high performance attributes including its exceptional weathering properties, stability, inertness, and resistance to chalking, fading, and UV.
In this article we look at the properties and benefits of PVDF coating, as well as where to find specialist applicators and products in Canada.

PVDF coating is a type of thermoplastic fluoropolymer, a class of coating that includes non-stick, low-friction coatings like Teflon. They are commonly used for industrial applications, medical coating, and cookware. PVDF coating is applied through the automated process of coil coating, used for architectural sheet metal and cladding, or can be applied post build. It is an incredibly versatile coating type that is known as the heavy duty option in the metal architectural coatings market. This is because PVDF coating has:
There are different grades of PVDF coating and each one is suitable for a different range of applications. The resin in a PVDF coating is a blend of PVDF and a proprietary mix of other resins. The coatings are named by the percentage of the resin component that is made up of PVDF – 80%, 70%, 50%. The higher the percentage of PVDF, the greater the strength of the coating’s protective properties. In Canada, where all manner of elements can attack a coating, 70% PVDF is the recommended blend for exterior applications.
The other most common blend is 50% PVDF. This option displays good UV resistance and weatherability, but is not as long-lasting or hard-wearing as 70%. Ultimately it comes down to cost and the protection requirements of the environment and use of the substrate. The higher the percentage of PVDF, the higher the cost.
A wide range of companies in Canada offer pre-painted steel and aluminium roofing and cladding for construction and building. These companies include coil coating company Material Sciences Corporation in Toronto, Color Steels in Thornhill, Ontario, and Wilkinson Steel in Vancouver. The coatings themselves are produced by various companies and have a number of trade names. The most popular of these are produced by AkzoNobel (the TRINAR range of 70% PVDF), PPG (the Duranar range of 70% PVDF), and the now-combined Valspar/Sherwin Williams (Acroflur 50% PVDF, Fluropon 70% PVDF coil coating, Flurospar, Flurothane).
