Aluminum profile powder coating
- Commodity name: Aluminum profile powder coating
- Product Description
-
Product Features1. Excellent adhesion, impact resistance, scratch resistance, high hardness, and good flexibility.2. High gloss and color retention, with excellent weather resistance.3. The addition of special conductive adjuvants and a laser laser particle size analysis control system allows the powder particles to have both electroconductivity and sufficient kinetic energy, making it easy to reach the grooves and dead corners, overcoming the phenomenon of difficulty in powdering in these areas (Faraday cage effect).4. Good leveling, no sagging, large spraying area, recycled powder sieving and proportional mixing do not affect the product quality and performance, high utilization rate.5. Wood grain, patterns, etc. can be transferred to meet decorative requirements.6. Green and environmentally friendly, free of heavy metals, and conforms to international standards.Powder coating film performance parameters after curing:
