How High-Pressure Airless Spraying Technology Enhances Road Marking Performance

Unlike traditional brush application or air-assisted spraying methods, the RS-350 utilizes a diaphragm-type high-pressure pump capable of generating pressures up to 25 MPa (approximately 250 kg/cm²). This force propels cold paint road marking material through the spray gun, forming a dense, bubble-free coating. The resulting lines exhibit exceptional adhesion and density, significantly reducing the risk of peeling or fading over time. This airless road marking equipment is particularly suited for applying clear, durable lines on asphalt, concrete, and other paved surfaces.
