PPGI Pre-Painted Galvanized
 
Polyester (PE): good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance and low cost. Silicon modified polyester (SMP): the hardness, wear resistance and heat resistance of the coating film are good, as well as good external durability and chalking resistance. The gloss retention and flexibility are general, and the cost is medium. High durability polyester (HDP): excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good film adhesion, rich colors and excellent cost performance. Polyvinylidene fluoride (PVDF): excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good formability, dirt resistance, limited color and high cost.
