Product Detail
Automobile accessory Powder Coatings
With the development and promotion of powder coatings, nowadays, they are widely used in automobile industry, and popular because of the properties of beauty, mobility sense, environment protection. Automobile industry becomes one of the biggest users of powder coatings.
Our powder coatings are made of polyesters, polyester/epoxy types, especial for accessories of automobiles and motorcycles, including engines, chairs, oil tanks, filters, rain scrapers, horns, reflectors, wheel hubs, gear boxes, etc.
We are researching and developing powder coatings especial for automobile industry, to meet the requirements of super properties, such as, anti weathering, corrosion resistance, wear resistance, heat resistance, gloss and color retention, etc.
