1. Basic Product Overview 

Acrylic powder coatings are high-quality paints that combine weather resistance, smoothness of the paint film, and vividness. They are particularly suitable for use in fields where aesthetics and weather resistance are emphasized, such as building materials, road materials, automotive parts, and aluminum wheels, where appearance and durability are demanded. 

2. Technical Details 

These coatings form an excellent paint film through the chemical reaction and curing of the carboxyl groups of acrylic resins with aliphatic dicarboxylic acids. Acrylic resins containing glycidyl groups enhance the durability and aesthetic appeal of the paint film, contributing to improved stain resistance and paint film hardness. The application by electrostatic powder coating method achieves a uniform and smooth finish, and in some cases, the use of a preheating method can further enhance the performance of the paint film. 

3. Advantages 

Acrylic powder coatings maintain aesthetics over the long term due to their excellent weather resistance. The characteristics of this paint provide a beautiful finish through high paint film smoothness and vividness. Moreover, the high stain resistance and paint film hardness also ensure practicality. 

4. Disadvantages 

Acrylic powder coatings may exhibit slight inferiority in flexibility and corrosion resistance, which needs to be considered in their use. Additionally, the high cost of raw materials can impact the economy of using this paint. Furthermore, risks such as paint film peeling can occur due to minor mixing with other powder paints, requiring special attention to this aspect.
