What Causes Craters In Powder Coating at Alannah Eric blog

What Causes Craters In Powder Coating. The latter may be a pulling apart of a film. Process controls should be implemented upstream of the coating line to prevent a defective substrate from entering the line. Crawling and cratering, 2 common paint defects, affect both the aesthetic & protective role of the coating film. Rejects from coating lines can come from a substrate defect, a surface contaminant or a coating material defect. Solvents, grease, mold release agents, and machine oil. These small holes penetrate through the coating, exposing the metal. Substrate or underfilm contaminants cause craters because the paint does not wet the contaminated area or immediately dewets. Because they are often mixed up,. One of the primary causes of pinholes is surface contamination. Tiny voids and craters called pinholes are another prevalent powder coating problem. Powder coating surface defects result in rejects. A crater is a blank area in the powder coat, which extends through to the substrate, it can be caused by inadequate pre treatment, rust, or incompatiblity. Some aerosol spray paints contain silicone, which will cause fisheyes and craters in powder applied over them.
