Prepainted Steel Coil (PPGI, PPGL) Coating type
2/1: Painted twice on the top surface, once on the back surface, and baked twice.
Application: The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion.To be applied to sandwich panels;
2/1M: Painted the top and back surfaces twice each, and baked once.
Application:The back paint has good corrosion resistance, scratch resistance and processing formability, and has good adhesion. It is suitable for single laminated board and sandwich board.
2/2: Painted the top and back surfaces twice each, and bake them twice.
Application: The double-layer back paint has better corrosion resistance, scratch resistance and processing formability. Most of them are used for single laminated board, but its adhesion is not good, it is not suitable for sandwich board.
Component Of Pre-painted Coils
Polyester (PE)
Good adhesion, rich colors, a wide range in formability and outdoor durability, moderate chemical resistance, and low cost.
Silicon modified polyester (SMP) has good film hardness, abrasion resistance and heat resistance, as well as good external durability and chalking resistance, gloss retention, general flexibility, and medium cost.
High-durability polyester (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 (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.
