(kodest)Advantages of primer-topcoat cathodic electrophoretic coating

Cathodic electrophoretic (CED) coating offers a superior finish compared to traditional painting methods. By applying both primer and topcoat in a single process, manufacturers achieve significant efficiency gains and enhanced product quality. This single-step application leads to several key advantages.

Uniform Coating and Excellent Film Adhesion

The electrostatic nature of CED ensures a uniform coating thickness, even in complex geometries, reaching into recesses inaccessible to conventional spraying. This uniform coating contributes significantly to improved corrosion resistance and a more aesthetically pleasing finish.
Furthermore, the strong electrostatic attraction between the paint particles and the substrate promotes excellent adhesion, minimizing the risk of peeling or flaking, leading to longer-lasting protection.

Enhanced Corrosion Protection

CED provides a complete coating that effectively seals the substrate against moisture and oxygen, crucial factors in corrosion initiation. The primer layer provides the initial barrier against rust and degradation, while the topcoat enhances the barrier and offers aesthetic appeal.
The uniform coating thickness achieved through CED minimizes pinholes and other defects that can compromise the protective barrier, resulting in superior corrosion resistance compared to other methods.

Increased Efficiency and Reduced Costs

The single-step application of both primer and topcoat in CED significantly reduces production time and labor costs compared to multi-stage painting processes. Less handling and fewer drying steps mean quicker turnaround times.
Reduced waste from overspray and the efficient use of materials further contribute to lower overall production costs.

(KODEST)hot air circulation radiation

(KODEST)hot air circulation radiation

A commonly used electrophoretic curing furnace is a gas direct heating curing furnace. This type of curing oven can cure all depressions, and its operating cost is also relatively economical. Sometimes, a radiation zone is also set at the entrance of the curing oven, where the circulating wind speed is lower and there is less dust in the air, which can reduce the viscosity of the cured surface of the coating and make it less susceptible to pollution from pollutants.

Sometimes a dehydration zone can also be set up, which is a heating channel. The workpiece is heated at a temperature of 60 ℃~70 ℃ for 2-3 minutes, and the dehydration zone is set at the entrance of the curing furnace.

The quiet operation of the system further enhances the user experience, ensuring a peaceful atmosphere without distracting noise. This silent performance makes it suitable for various settings, including bedrooms and living spaces, where noise pollution can be disruptive.
