Appearance Recognition Method of Powder Coatings

1. Hand feeling of powder coating: the hand feeling is silky smooth, loose and floating. The hand feeling is rough and heavy. If you hold a handful of powder in your hand, the more smooth and loose the powder is, the better the quality is. On the contrary, the powder is rough and the hand feeling is heavy, and the quality is poor. The powder coating with poor quality is not easy to spray, and the secondary powder dropping is more and the waste is large.

2. The volume of powder coating: the larger the volume, the less the filler in the powder coating, and the higher the cost. The better the quality of powder. The smaller the volume, the higher the filler in the powder coating, and the lower the cost. The worse the quality of powder. For the same carton, the bigger the powder volume, the better the powder; Small volume means poor powder. Poor quality powder coatings are not easy to spray, with more secondary powder falling, more waste, less spray area and high cost.

3. Storage time of powder coating: good powder coating can be stored for a long time, and the leveling and other effects of powder remain unchanged. Poor powder coating cannot be stored for a long time, and the leveling and other effects of poor powder become worse after 3 months. The shelf life of normal powder at room temperature is 12 months, and the quality of low-end raw materials is unstable and easy to degenerate, In addition, the powder is not easy to store, which results in a large waste of powder and a large amount of reimbursement for customers.

The powder coatings produced by milestone Industrial Co. Ltd. are smooth and bulky. Storage time after 12 months, excellent performance, easy spraying construction, less secondary powder, the same spraying area, usage, help customers save costs.
