There are two common surface treatment methods: liquid spray painting and powder coating.

Each has its own advantages, but with stricter environmental regulations, powder coating has gradually become the mainstream. Environmentally friendly: Traditional spray painting uses organic solvents, which release VOCs (volatile organic compounds) upon evaporation, polluting the environment. Powder spraying is solvent-free and has a recycling rate of up to 98%. Coating performance: Liquid paint films are thin and have poor wear resistance. Powder coatings are thick and highly corrosion-resistant. Cost: Traditional spray painting results in significant material waste and high labor and maintenance costs. Powder spraying equipment requires a large initial investment, but has low operating costs.

Summary: Powder spraying significantly outperforms spray painting in terms of overall performance and is particularly suitable for large-scale industrial production. Write an SEO title, description, and keywords for this article.
