One of the main functions of electrical and bus bar plastic coating is to protect the metal surface from corrosion. The coating forms a barrier between the metal and the environment, preventing contact with moisture, oxygen and other elements that can cause rusting. Additionally, a coat of plastic can help improve the appearance and durability of the metal surface.

Metal finish plastic coatings can be applied to a variety of products to improve their appearance and performance. Some of the most common applications include automotive parts, appliances, and packaging. The coatings can help protect the metal from corrosion, scratches, and other damage. They can also make the surface more resistant to stains and dirt buildup. 

The life of the electrical and bus bar plastic coating largely depends on the environment in which it is used. If the environment is relatively clean and dry, the coating can last for many years. However, if the environment is dirty or wet, the coating may not last very long. In general, most coatings will last for at least five years, but they may need to be replaced more frequently in dirty or wet environments.

Natural characteristics of most plastic resins make them ideal solutions for the electrical industry, including:

• Excellent insulation capabilities (high dielectric strength, low conductivity)
• Resistance to moisture, chemicals, corrosion, and oxidation
• High performance in extreme conditions
• Barrier against dust, debris, environmental contacts
• Resistance to impacts, abrasions, and other physical damage

Yes, plastic coatings offer the combination of insulation and protection high-voltage equipment and tools need to have to maintain safety and work smoothly. 

Epoxy, vinyl, and plastisol are three of the most common coatings for both the small bus bars in electronics and the larger bus bars used in higher-voltage environments such as power generation and storage.

Plastisol is a popular dip coating for electrical equipment and tools used in electrical work, standing up to the challenges of protection in harsh environments. Epoxy, vinyl, polyolefin, Halar™ and nylon are also commonly used for electrical applications, applied by fluidized bed or electrostatic spray. 

At the simplest level, plastic coatings keep electricity where it should be, and protect people, animals, other components, and objects from coming into contact with electrical current. Plastisol coatings on tools offer additional protection to workers, especially when working in hazardous weather conditions.
