Radiator-Specific Powder Coating

Radiator-Specific Powder Coating About

1. Product Overview

Based on the special requirements and structural characteristics of radiator products, our company has developed a dedicated powder coating specifically for radiators. This coating effectively eliminates common coating defects such as blisters and pinholes, while significantly improving powder penetration into hard-to-reach areas during spraying. At the same time, it enhances the coatings mechanical properties, surface hardness, and adhesion.

2. Product Features

(1) Excellent leveling performance and outstanding adhesion.

(2) Superior delayed impact resistance. Even after years of service, the coating maintains excellent flexibility and durability.

(3) Excellent resistance to stains and edible oils, allowing the coated surface to withstand repeated cleaning without performance degradation.

3. Energy-Saving Benefits

Low-temperature curing: Fully cures at 130C for 25 minutes, reducing baking energy consumption by approximately 25% and lowering coating costs.

High powder transfer efficiency: Large spraying coverage area, with each kilogram of powder capable of coating approximately 89 m of flat surface, reducing raw material consumption by approximately 30%.
