Discussion on Factors Influencing the Flowability of Powder Coatings for Electrostatic Spraying of Aluminum ProfilesPowder coating is a type of coating that is dispersed and painted with air as a carrier. It is a typical "4E" (efficient, economic, ecological, and energy) product, which grows at a ra

(1) high quality cold rolled sheet with thickness less than 1mmNo pinholes will appear after painting. If there is a crack, because there is air in the crack, coating solidification may cause coating interruption and discontinuity, that is, large pores;A porosity is caused by rust or dirt on the sur

The reason for the pinhole in the spray is related to the following points:1. The workpiece has a small amount of water or oil on the surface before spraying. When the temperature is solidified, the oil or water evaporates and vaporizes, leaving pinholes on the workpiece.2. If the pinholes are one p
