Polyurethane powder coating

Product name: Polyurethane powder coating

General introduction:

The powder coating made of hydroxyl polyester resin, with excellent leveling, chemical resistance, weather resistance and strong oil resistance. Suitable for automobile, motorcycle, tanker and agricultural machinery for chemical resistance, oil resistance of coating metal appearance of higher requirements.

Product Series:

Can provide gloss (more than 80%), half-gloss(50-80%), semi-gloss (20-50%) and matt (20%) products. (According to the needs of users control gloss)

Powder physical properties:

proportion(g/cm³, 25℃)：1.4-1.7

Distribution of particle size: 100% less than 60um (can be adjusted according to special requirements of coating)

Curing conditions: 200℃(workpiece temperature), 10 minutes
