Radiator Powder Coating

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.
