What causes paint to repel? Three key points not to overlook regarding repelling defects.
A paint defect that causes a round dent due to paint escaping. The root cause is not degreasing, but the oil content in the airline. This explains the key points of pretreatment and equipment management.
The moment the paint is applied, it escapes and creates a round dent. If changing the paint doesn't fix it, the cause lies with the materials and equipment. Eighty percent of the sources of paint beading are oil and silicone. ────────────── ■ Causes of Occurrence If oil or silicone remains on the painted surface, the surface tension changes in that area. The paint cannot spread and results in circular dents with a diameter of 1-3 millimeters. ■ The Truth The real culprit is not the degreasing process but the airline. Oil contained in the compressor's drain adheres to the parts just before painting. Silicone-based release agents and hand creams can also be sources of contamination. ■ Improvement Measures Implement a two-stage air filter and perform daily drain discharge. Manage the oil concentration of the degreasing solution and prohibit handling with bare hands. Please utilize the materials summarizing the standards for pretreatment and equipment management.
