Recyclability of metal powder coating

Metal powder coating can be recycled. Some problems should be paid attention to in recycling.

As for the metal powder coating made by dry mixing method, the phenomenon of separation will occur in the process of spraying and recycling, so the recycled metal powder coating and the new metal powder coating will have certain differences in the content of metal pigment, which may lead to different appearance of the film and color deviation.

This is due to the different properties between metallic pigments and powder particles. Our engineers advocate that the ratio of recycled metal powder coating to new powder coating should be at least 1:4.

If the use of adhesive fixed method to produce powder coatings, because the ratio between metal pigments and powder particles is relatively fixed, it can be used from scratch to recover powder.
