Ultrafine spray particles enable large atomization at a atomization height, keeping the work surface dry for clean, residue coatings. Low dielectric loss and low heat generation reduce energy waste and thermal buildup; resistant to acids and alkalis for a long service life. Low driving voltage, low power consumption, low impedance, and stable waveform deliver reliable operation with conversion efficiency. Silver layer protection coating process provides enhanced durability, with life expectancy up to 3000 hours. Use scenarios Electronics protection coating: suitable for coating printed circuit boards, sensors, and small components to achieve uniform coverage while keeping the substrate surface dry. Harshenvironment coatings: ideal for protective coatings on parts exposed to acids or alkalis, where material resistance and longevity matter. Lab and smallscale manufacturing: supports energyefficient, stable spray applications for delicate parts requiring long service life and consistent performance.
