Coating types of color coated rolls
1. Polyester (PE): As the coating of the color coating roller, polyester has the characteristics of good adhesion, rich colors, wide range of moldability and outdoor durability, medium chemical resistance, and low cost.
2. Silicon modified polyester: SMP, the hardness, wear resistance and heat resistance of the coating film are good, as well as good external durability and crush resistance, gloss retention, general flexibility and medium cost.
3. High-durability polyester (HDP): good color retention and UV resistance, better outdoor durability and crush resistance, good film adhesion, rich colors and good cost performance.
4. Polyvinylidene fluoride (PVDF): good color retention and UV resistance, good outdoor durability and crush resistance, good solvent resistance, good moldability, dust resistance, limited color And high cost.
