Baosteel photovoltaic color steel plate, anti-static color coated plate, fluorocarbon coated color steel coil supplied by LuoxinPerformance of front coating on color coated board1. Types of CoatingsPolyester (PE)Good adhesion, wide range in formability and outdoor durability, moderate chemical resistance.The hardness, wear resistance, and heat resistance of silicon modified polyester (SMP) coating are good, as well as good external durability and powdering resistance, limited gloss retention and flexibility.High weather resistant polyester (HDP)Excellent UV resistance and high durability, its main performance is between polyester and fluorocarbon.Polyvinylidene fluoride fluorocarbon (PVDF)Has good formability and color retention, excellent outdoor durability and anti powdering properties, solvent resistance, but limited color2. Coating thicknessThe coating structure is divided into two coatings and one baking and two coatings and two baking. The coating thickness is generally 20-25u on the surface and 8-10u on the back. For external use of buildings, it should not be lower than 20u on the surface and 10u on the back. The standards commonly used for colored coated steel plates are ASTM A527 (galvanized) and ASTM AT92 (aluminum zinc plated) in the United States, JIS G3302 in Japan, EN/0142 in Europe, KS D3506 in South Korea, and Q/BQB440 in Baosteel.
