Electrostatic coating is powder coating by Minoru Sangyo Co., Ltd.

Electrostatic painting is a coating method that uses the power of static electricity to apply paint, as the name suggests.

◆Features of Electrostatic Coating Due to the force of static electricity, the paint is attracted to the object, allowing for efficient adhesion (high coating efficiency). Additionally, because the paint moves along electric field lines, it can be applied not only to the front of the spray gun but also to areas that are wrapped around and corners where compressed air has no escape, which is a characteristic of this method. The drawbacks include the tendency for paint to concentrate on convex areas where the electric field is concentrated, and there may be instances where paint adheres unexpectedly far away. Moreover, since high voltage is used, it is necessary to be cautious of electric shock accidents and the risk of fire. ◆Advantages of Electrostatic Coating 1. Easier to achieve a uniform paint film Because the paint is attracted by static electricity, it can be sprayed widely, allowing for relatively uniform adhesion of the paint. Adjusting the nozzle opening reduces the likelihood of uneven spraying, making it easier to obtain a uniform paint film. 2. Less paint loss In conventional spray painting, paint that misses the object or does not reach it becomes waste. In electrostatic coating, the proportion of paint that is attracted due to adhesion increases, which is expected to reduce paint loss.
