Advantages Unique advantages of polyester coating series:
A. Ultra-long resistance to sunlight, rain and other natural factors
B. Excellent scratch resistance
C. Super anti-pollution ability
D. Excellent adhesion
E. Excellent flexibility and processability
F. The warranty period can reach 5& 10 years
Base material polyester coating can be widely used in various pre-treatment base materials: aluminum plate, hot-dip galvanized plate, zinc-aluminum plate for building materials, aluminum-zinc plate
The application of polyester coating is the ideal choice for long-term exposed civil buildings, commercial areas and building prefabricated parts, including: residential metal wall panels and roof structures, interior panels, doors and other metal building components for decoration
The color polyester coating series can provide a variety of color choices, and the ceramic pigments in its formula can make the color lasting as new
