Hardware & Plastic Electrostatic Spraying: Full Coverage Coloring with Strong Adhesion & No Paint Peeling

Conventional spraying often causes missing coating, peeling and scratching on hardware and plastic workpieces. As a mature surface coloring technology, electrostatic spraying relies on electrostatic adsorption to realize full-coverage coloring. With standardized pretreatment, it delivers far stronger coating adhesion and durable performance, widely used in mass processing of home appliance parts, chassis shells and plastic structural components.

Thanks to electrostatic field attraction, coating powder can actively adhere to all workpiece surfaces. It perfectly covers dead corners, grooves and bent edges that ordinary spraying cannot reach, achieving uniform coating thickness without color difference or bare base, eliminating secondary manual touch-up.

Reliable anti-peeling performance depends on targeted pretreatment. Metal parts undergo degreasing and phosphating, while plastic parts receive surface activation to enhance adhesion. After electrostatic powder spraying and high-temperature curing, the coating forms a firm occlusal connection with substrates. It passes cross-cut and tape adhesion tests without peeling off.

Eco-friendly and scratch-resistant, electrostatic spraying features recyclable powder and zero harmful volatile emissions. The cured coating resists abrasion, acid and alkali corrosion, meeting long-term indoor and outdoor use demands for industrial workpieces.
