Insulating Coating is a surface treatment service that forms an insulating film on the surface of metals, electronic components, and other materials to enhance electrical insulation and corrosion resistance.
This service utilizes diverse coating materials such as resin-based, inorganic, and ceramic types.The optimal insulating film is selected based on the product's application and operating environment.Uniform films are formed using techniques such as spraying, dipping, and vacuum deposition, enabling processing even for micro-sized components.
To ensure stable performance, processes emphasizing adhesion and heat resistance are applied.As a result, insulating properties are maintained even in high-temperature and high-humidity environments.
Insulating Coating is widely used in fields where electrical safety and reliability are paramount, including electronics, automotive, and medical devices.Particularly in today’s era of increasingly miniaturized and densely packed electronic circuits, it is an indispensable surface treatment service supporting long-term component reliability.
Insulating Coating, which protects various components, is widely used primarily for the following applications:
An insulating film is formed on printed circuit boards and semiconductor components to protect them from moisture, dust, and chemicals. This effectively prevents short circuits between circuits and improves long-term reliability.
When applied to motor windings and coils, the coating enhances heat resistance and insulation properties. This ensures stable operation in high-voltage environments and extends product lifespan.
In lithium-ion batteries and power modules, insulating coatings prevent short circuits between electrodes, improving safety and durability while maintaining performance under harsh conditions.
Insulating films formed on sensor elements for temperature, pressure, and humidity measurement protect against external noise and moisture. This contributes to stable measurement accuracy and reliable operation.
Insulating coatings are used to ensure medical device safety and to provide insulation and anti-corrosion treatment for aircraft and automotive components. This technology is indispensable in fields that demand high levels of reliability.
