radiator powder coating

Main features of radiator powder coating:

1, excellent leveling, high gloss and high degree 

of saturation

2, plus the adhesion

3, good delay impact performance, coating after a few 

years, still have a very good flexibility

4, can meet the requirements of the molding, 

resistance to repeated bending

5, excellent oil resistant, oil resistant performance, can be 

repeatedly Scrub

Energy saving of radiator powder coating:

1, low temperature curing 

(120C*25min curing), can save 25% of the baking energy to reduce coating cost.

2, high 

powder rate of high spray area, per kilogram of powder spraying area can reach 8-9 square 

meters, saving raw materials 30%.
