The prepainted steel coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, and galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating), followed by baking and curing.
The total thickness of the pre-panted galvanized steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm.
Usually, the paint coating material is polyester (PE) and the color of the back paint is white grey. From Wayen Fctory,The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print, camouflage, brick.
Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, and low cost.
Silicon modified polyester(SMP): Good 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 anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, stain resistance, limited color, and high cost.
