Powder Coating Technology: March 1999

 

Powder Coatings Expected to be Popular for Low Pollution and Resource Efficiency

Powder coatings are a coating technology developed to reduce environmental impact and improve resource efficiency. Compared to traditional liquid coatings, they significantly reduce the emission of volatile organic compounds (VOCs). The reasons why this technology is expected to become popular are as follows.

1. Reduction of Environmental Impact

Unlike liquid coatings, powder coatings do not contain solvents, so they do not cause air pollution due to the evaporation of organic solvents during the coating process. This significantly reduces the emission of VOCs during both the coating process and the drying process, improving the working environment and reducing adverse effects on the environment. Additionally, since powder coatings are supplied in solid form, the risk of leakage during transportation is also reduced.

2. Improvement of Resource Efficiency

Powder coatings are also superior in terms of coating efficiency. Their use results in less overspray during the coating process, and the high adhesion rate to the coated objects means less waste. Moreover, excess powder coatings can be collected and reused, promoting effective use of resources. The introduction of such recycling systems reduces the amount of paint used and minimizes waste generation.

3. High Durability and Quality Improvement

Powder coatings are excellent in terms of weather resistance and abrasion resistance, providing long-term protection for the coated surface. This reduces maintenance costs and extends the life of the product. Additionally, powder coatings form a uniform film thickness, contributing to improved coating quality. Curing at high temperatures creates a hard and durable coating that is resistant to chemicals and UV radiation.

4. Consideration of Safety and Health

Powder coatings also take into account the health impact on workers. Since they do not contain solvents, the risk of workers being exposed to harmful chemicals is reduced. Furthermore, powder coatings are less flammable and have a lower risk of ignition, providing a high level of safety. This offers a safe and healthy working environment, reducing the risk of occupational accidents.

Summary

Powder coatings have many advantages in terms of environmental protection, resource efficiency, high-quality coating, and safety. Due to these features, further development and adoption of this technology are expected. Especially in the fields of automotive, construction, and home appliances, the use of powder coatings is anticipated to advance, contributing to the realization of a sustainable society.
