Warranty for Surface Coating – 15 Years
Duracoil products come with 15 years warranty against defects resulting in Cracks, Peeling, Loss of Adhesion, Flaking, Blistering, Whitening of Pitting. Conditions of warranty shall apply as fading or color degradation of coated surfaces are dependent on several Factors.

Light and Dark Colors
Color degradation or fading is mostly caused by nature’s effect on the materials organic PVDF resins used in the paint. Whilst Polyvinylidene Fluoride is one the strongest chemical bond in nature, the presence of UV light will eventually caused the break down of the chemical bond. When such events occur, the coated surfaces will present a whitish powdery film, an effect known as pitting. As the whitish powder is carried away by rain, wind, sand etc, the surface is once again exposed to the UV radiation. Such cyclical weathering effects will eventually take it’s toil on the product as the material loses surface thickness. With the removal of surface material from the coated surface, the fa?ade will appear “aged” or old.
