source：www.cnjindu.com | Release time：2026年08月04日Core advantages
1. Excellent weather resistance and UV resistance (core feature)
Saturated polyester has a stable molecular structure and outstanding resistance to UV aging. It is not easy to fade, lose light, or powder after long-term outdoor exposure to sunlight. Compared to epoxy powder and mixed powder, it is very suitable for outdoor environments; Ultra weather resistant polyester can meet the long-term use standards of building aluminum profiles.
2. Environmental protection and safety, zero solvent VOC
100% solid powder, free of organic solvents; Electrostatic spraying, the powder after spraying can be recycled and reused, with high material utilization rate, meeting the requirements of environmentally friendly coating.
3. Balanced mechanical performance
Excellent adhesion of paint film, good adaptability to cold-rolled sheet, galvanized sheet, and aluminum alloy substrate; It has good impact strength, flexibility, and hardness, and the workpiece is not easily cracked or detached during bending and assembly.
4. Rich decorative elements and a wide range of appearance options
Excellent melt leveling, with a smooth and full paint film; Multiple effects such as high gloss, semi gloss, matte, sanding, and metallic glitter can be adjusted, and the color system is complete to meet diverse appearance needs.
5. Good anti-corrosion and moisture-proof performance
Forming a dense and continuous paint film, effectively blocking water vapor, with excellent neutral salt spray performance, combined with perfect pre-treatment, can achieve long-term rust prevention and protection.
6. Stable construction technology
Excellent electrical performance and good Faraday cage penetration; Curing window width (conventional 180-200 ℃), easy to control in batch production process; Good storage stability and not easy to clump.
7. Balanced cost-effectiveness
The performance is between mixed powder and fluorocarbon powder, balancing outdoor durability and cost, making it an ideal choice for outdoor metal coating.
