For powders produced by dry blending, due to separation during spraying and recycling, there will be differences in metallic pigment content between recycled powder and virgin powder, which may result in inconsistent appearance of the coating film and color cast.
For powders produced by dry blending, since separation occurs during spraying and recycling, there will be differences in the content of metallic pigments between the recycled powder and the new powder, which may lead to inconsistent appearance of the coating film and color cast. This is due to the difference in properties between metallic pigments and powder particles. We recommend a ratio of recycled powder to virgin powder of at least 1:4. If the powder coating produced by bonding and fixing method is used, the recycled powder can be reused because the ratio between the metallic pigment and the powder particles is relatively fixed.
