The rapid development of coating machine —

Twenty years ago, there were only more than 1,000 varieties of adhesives produced in China, which were mainly used in coating machines. The production of adhesives is very low, the scale is small, and the variety is not rich, let alone environmental protection requirements. At that time, the adhesives produced in China were basically only some traditional general-purpose products such as 502 instant glue, homopolymerized white latex, trisaldehyde glue and neoprene.

However, with the passage of time, China’s adhesive industry has been continuously developed and expanded, especially the development of those three-funded enterprises is even faster. Since then, China’s adhesives and sealants have been significantly improved in quality and quality, and many new technologies, new equipment and new products have been gradually developed. Through continuous innovation, we not only developed many new products, but also improved and improved the performance of traditional general-purpose products through copolymerization, cross-linking, grafting, etc., which greatly reduced or eliminated the content of harmful substances. The industrialization of enterprises.

In this short period of 20 years, China has developed many new products, such as modified epoxy resin, polyurethane structural adhesive and sealant, modified acrylate adhesive, hot melt adhesive and hot melt pressure sensitive adhesive, anaerobic Glues, silicone sealants and adhesives, etc. These products are widely used in various fields, so the coating machine industry in China has been rapidly developed.
