Color Coated Steel Coil for Household Appliances
Short Description:
Color Coated Steel Coils are high-gloss, pre-painted metal sheets engineered for appliance exteriors requiring scratch resistance (≥3H pencil hardness) and chemical resilience. Featuring dual-coat polyester-epoxy systems, these coils achieve 15+ years UV resistance (ASTM G154 Cycle 4) with 50+ RAL/Pantone color options. The frontside uses 30µm oil-free polyester resin for mirror-like finishes, while the backside applies 20µm modified epoxy to withstand detergent corrosion (pH 3–12).
