Bonding is an ancient and common connection method used by humans. The paste used in life and the bone glue used in woodworking have a history of thousands of years. Only after the development of new polymer materials, bonding technology has been widely used in modern industry, agriculture and other industries. The industrial application of sealants began as early as the wood processing industry to make plywood. With the development of science and technology, the variety of sealants is increasing. In the 1950s, butadiene epoxy resin adhesives appeared, and in the 1960s, hot melt adhesives appeared. In recent years, the second and third generations of acrylate adhesives have emerged. Although the development history of the sealant industry is not long, it has developed rapidly and has become an indispensable sector in the industry. Judging from the development trend of most industrialized countries, sealants have already played a key role in the revolutionary changes in material science and processing technology in the world. They are playing an increasingly important role in various sectors of the national economy. Due to the extensive use of sealants, a variety of new materials have emerged, promoting the development of cutting-edge technologies, and have penetrated from daily life to machinery, shoemaking, light industry, printing and bookbinding, medical, textile, aerospace, radio technology, Construction, ceramics, glass, technical materials, plastics and other industrial fields.
