Coating type of PPGI steel coil
Polyester (PE)
Good adhesion, rich colors, wide range in formability and outdoor durability, moderate chemical resistance, and low cost.
Silicon modified polyester
That is (SMP), the hardness of the coating film, abrasion resistance and heat resistance are good, as well as good external durability and chalking resistance, gloss retention, flexibility, and medium cost.
High durability polyester
Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good paint film adhesion, rich colors, and excellent cost performance.
Polyvinylidene fluoride
Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, dirt resistance, limited color and high cost.
