Color-coated coils are based on hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or more layers of organic paint are applied to the surface, and then After baking and curing products. It is named after the colored steel coil coated with various organic coatings of different colors, referred to as color coated coil. Product Description Product name Prepainted steel coils Material galvanized steel coils, galvalume steel coils Color As per the RAL code or based on the sample Thickness 0.13mm-1.0mm Width 750mm-1250mm Color paint coating Top coating of 12-25micro, bottom coating of 5-10micro Introduction: Color-coated coils are based on hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or more layers of organic paint are applied to the surface, and then After baking and curing products. It is named after the colored steel coil coated with various organic coatings of different colors, referred to as color coated coil. Coating type of pre-painted 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.
