A superfine powder paint features that its spherical particle made of resin has 15-25 microns in diameter and contains SiO2. It is prepared through heating the powdered raw materials to fuse them or locally fuse them while jetting the fused liquid out, and cooling to become particles. Its advantages are high flowability and smooth and thin painted layer.
