Thermoset polyester powders are produced on the basis of high grade polyester resin specialized for powder coating production.
The products may provide coating film with toughness and durability, high gloss, good weatherability, especially outdoor exposure durability, heat resistance and excellent anticorrosive and anti-blooming properties.
Feature:
-
1. Excellent adhesion, impact resistance, scratch resistance, high hardness, good flexibility
2. High color retention rate, with excellent weather resistance
3 Add special conductive aids and with laser particle size analysis and control system, so that the powder particles taking charge and sufficient flow performance, it is easy to reach the groove, dead ends, to overcome the difficult powder phenomenon (Faraday cage effect)
4 Good leveling, no sagging, large spraying area, recycled powder sieving in proportion not affect the product quality performance, high utilization
5 green, non-heavy metal, in line with national standards
