A composite material for appliances, featuring organic-coated surfaces. Zhongwei home appliance panels combines vibrant colors with steel’s strength and superior formability, while the paint layer ensures corrosion resistance and flexibility—ideal for durable, high-performance appliance manufacturing.
Applications
PCM products can be applied to refrigerators, washing machines, water heaters, microwave ovens, set-top boxes, DVDs, TV back panels, air conditioners, ship decoration, interior decoration, high-end cabinets and other products.
PCM boards are available in different colors, are directly stamped and formed, and do not lose paint. They have become the leader in home appliance color board industry and truly lead the trend of home appliance appearance.
Why Choose Zhongwei Home Appliance Panels?
Engineered for precision, our appliance-grade color-coated coils combine durability, aesthetic consistency, and eco-friendly formulations to meet the highest global standards for modern home appliance manufacturing.
How to select coatings on home appliance coils ?
1. Coating Layers:
- Single/Dual Layers: Achieve 0T bend performance with balanced flexibility and adhesion for high-stress forming (e.g., refrigerator panels).
- Multi-Layer Systems: Enhance aesthetics and corrosion resistance but may sacrifice flexibility.
2. Primer:
- Uses medium/high-molecular polyester with amino/blocked isocyanate crosslinkers for superior adhesion and bendability.
3. Topcoat:
- Block Polymerization Technology: Combines soft/hard resin segments to balance hardness (>2H) and flexibility (0T bend). Customizable for scratch resistance, color consistency, and acid/alkali tolerance.
4. Backing Coat:
- Thin, single-layer coatings with high MEK/salt spray resistance, anti-scuff properties, and conductivity for foam lamination compatibility.
Pre-coated metal (PCM) Applications
Our color-coated coils are widely used in refrigerators, washing machines, water heaters, microwave ovens, set-top boxes, DVDs, TV back panels, air conditioners, marine interiors, premium architectural finishes, and high-end cabinetry, offering durability, aesthetic versatility, and corrosion resistance for both functional and decorative applications.
Zhongwei coatings deliver tailored performance for appliances—optimizing hardness, corrosion resistance, and eco-compliance (RoHS) while ensuring vibrant, durable finishes.

Performance Requirements for Appliance Color-Coated Coils
1. Adhesion: Superior coating adhesion is critical. Unlike standard construction panels (T-bend ≤3T), appliance-grade sheets require **0T** to prevent cracks during bending (e.g., refrigerator/AC casing fabrication).
2. Hardness: High scratch resistance (>2H pencil hardness) is essential for processing and daily use, balancing hardness with adhesion via advanced resin formulations.
3. Color Consistency: Strict color deviation control for white/near-white finishes (common in appliances).
4. Acid/Alkali Resistance: Enhanced resistance to withstand frequent exposure to detergents and chemicals (e.g., washing machines, refrigerators).
5. Eco-Compliance: Meets EU RoHS Directive—**PVC-free** and **heavy metal-free** (e.g., chromium-free coatings, no PVC laminated sheets).
