HomeHow PVDF Kynar 500® finish provides superior performance on metal roof and siding ?

Tuiles 3R offers you products in steel and aluminum including finish treatment that provides superior durability and optimal resistance to cleaning of graffiti on sidings.

KYNAR 500® and HYLAR 5000® surface finishing products are currently the best treatment products for the siding and metal roof in aluminium and steel. All products from Atas International, Inc., are treated with KYNAR 500® or HYLAR 5000®.

Comparative tests with other finishing products have shown that the KYNAR 500® / HYLAR® 5000 achieve better results at the level of resistance to UV rays, abrasion, fading, chemicals, solvents. This treatment also allows to clean stains and graffiti without leaving visible traces or damage the coating.

KYNAR 500® and HYLAR 5000® are compounds of polyvinylidene fluoride (PVDF). PVDF is also used and tested in multiple industrial applications where the product is exposed to extreme variations in temperature as well as multiple chemical corrosive elements.

The comparative strength of the surface treatment of PVDF Kynar 500® was assessed in laboratory tests. Among the results, Kynar 500® has much better resisted testing solvent cleaning compared to acrylic based products.


The material for roofing and exterior wall (siding, attic) is mainly composed of four elements: the gauge steel sheet 26, a galvanized metallic coating (zinc or zinc-al alloy various treatments of adhesion of products, a primer coat and a top coat (color). Tiles 3R manufactures all its roofing tiles and exterior wall with prepainted (Perspecta) gauge steel 26 or others, as well as aluminum (Kynar 500 PVDF) of varying thicknesses (.030, .040, .050).

These processes improve resistance to corrosion, particularly against surface scratches and at the level of the curvatures of fold.
