Electrostatic powder coating is an environmentally friendly dry coating technology. Its core principle is to use high-voltage static electricity to make powder coatings (solid powder, solvent-free) adhere to the surface of workpieces, which then form a uniform and dense protective coating after high-temperature curing. It is widely applied in the surface treatment of metal materials (such as pre-painted sheets, steel structures, and hardware).
Core Features
– Environmental Friendliness: No solvent volatilization, no VOCs (Volatile Organic Compounds) generation, and the powder can be recycled and reused (recovery rate over 95%), complying with environmental policy requirements.
– Excellent Coating Performance: High film hardness (above 2H), strong adhesion (cross-cut test ≥ Grade 1), and superior corrosion resistance, wear resistance, and anti-fading performance compared to traditional liquid coating. The coating is uniform without sagging.
– Economic Efficiency: Simplified construction process (no multiple coating procedures of primer and topcoat), short curing time (15-30 minutes), high production efficiency, and low long-term operation and maintenance costs.
– Wide Application Range: Suitable for metal substrates such as steel and aluminum alloy, supporting various coating effects including flat coating, sand texture, and hammer texture, with a rich selection of colors (custom color codes available).
