The coating types currently used for PPGI/PPGL steel coil including PE, PVDF, SMP, Acrylic, PVC, etc.
The PE color-coated steel sheet is easy to process and form because of its good adhesion, and the price is relatively cheap. But accordingly, it possesses certain UV and anti-aging properties. PE color coated steel can be used for the roof of ordinary civil buildings.
SMP steel plate has better durability, and the cost is higher than the PE coating. Silicone is not as good as PE in terms of adhesion and processing formability to materials,
It is better than ordinary SMP coatings, and it has good outdoor weather resistance. It could have as long as 16 years of life time.
PVC coating has nice anti-chemical and anti-water characters, and the coasting is relatively thick, which can well protect the substrate.
Using PVC coating PPGI sheets should consider it's pulution to the environment.
PVDF coatings have great color retention and corrosion resistance. Among the PPGI sheet coating for construction, it is the highest grade.
