Water-based coating glue coating process FAQ and measures, how much do you know?

This article mainly focuses on the disadvantages that usually occur during the finishing process of water-based coating adhesives, including: striped crosspieces, pinholes, rough blisters, stickiness, stiffness, glue bleeding, car roads, fish eyes, and edges with medium thickness differences. Problems such as color difference, poor color fastness, and coating film peeling. Control the process of base fabric, size, and supporting additives, and propose solutions to effectively enhance the quality of coated fabrics. Coating processing is a novel textile finishing technology. Coating is to uniformly "coat" the surface of textiles to form polymer compounds that can form a film, so that the fabric can change its appearance, style or endow it with various functions, so as to increase the added value of the product. The polymer materials that can be used for coating mainly include: polyvinyl chloride, rubber, polyacrylate, polyurethane, silicone elastomer, polytetrafluoroethylene and various modified materials. These materials can be solvent-based, water-soluble or water-based Dispersion type. Due to the continuous improvement of the synthesis technology of water dispersion type, it has developed rapidly in application in recent years. Compared with solvent-based materials, it has the advantages of simple operation, cleanness, no environmental pollution, large change in performance style, and wide product coverage. .Affected by market factors, it is a foregone conclusion that water-dispersed (water-based) replace solvent-based. Therefore, how to effectively use water-based coating finishing agents to avoid and solve various problems in time has become more and more important.
