It has general durability, coating hardness and good flexibility and also it is affordable. Molding and outdoor durability performance is better, the applicable life is 8-10 years. PVDP has great UV resistance, but it cannot block UV by itself. It is necessary to use the pigments in the coating to achieve the function of blocking UV, so that the primer is not subject to UV erosion. Therefore the pigments must have great weather and chemistry resistance to withstand the blazing sun for quite a long time. But it is also the most expensive.

Roof panel is a part of the building envelope system, which bears waterproof, anti-corrosive and other functions. Therefore, there are many problems about the roof panel that need attention.
