Surface Finish Options Overview
Main Features of Radiator Powder Coating
Excellent leveling properties, with high gloss and high color saturation
Exceptional adhesion
Good delayed impact resistance; the coating remains highly flexible even after several years
Capable of meeting post-forming requirements and withstanding repeated bending
Superior oil resistance and cooking oil resistance, allowing for repeated cleaning
Energy Efficiency of Radiator Powder Coating
Low-temperature curing (120°C for 25 minutes), saving 25% of baking energy and reducing coating costs.
High transfer efficiency and large coverage area; each kilogram of powder can cover 8-9 square meters, saving 30% of raw materials.
