With the continuous improvement of automotive manufacturing technology, the development and application of new varieties of automotive adhesives are in the ascendant, involving five major categories of adhesive types required throughout the entire automotive manufacturing process, with more than 40 varieties in total. During the continuous development of China's chemical industry, the increasing richness of raw materials, and the continuous innovation of synthesis methods and production equipment, the varieties of adhesives suitable for automotive use will continue to increase. In the future, automotive adhesive varieties will develop towards the directions of green and environmentally friendly types, high-performance types, and multi-functional types. Water-based adhesives, hot-melt adhesives, low-density plastisols, high-strength structural adhesives, etc., which meet the usage requirements and process performance requirements of automotive products, will be applied more widely.

Automotive adhesives refer to various adhesives and sealants used in the automotive production process, including five major categories of adhesive types used in automotive body welding, painting, final assembly, engine, chassis components, and manufacturing processes. A high-quality modern car involves the application of more than 30 types of adhesives. They play important roles in aspects such as component reinforcement, fastening and loosening prevention, sealing and rust prevention, vibration and noise reduction, heat insulation and sound absorption, interior and exterior decoration, and simplification of the manufacturing process of automotive products.

Adhesives have many characteristics such as a wide range of applications, simple usage, and high economic benefits. With the development of the economy and the progress of science and technology, synthetic adhesives are increasingly replacing mechanical connections, and their applications have expanded to fields such as wood processing, construction, automobiles, light industry, clothing, packaging, printing and binding, electronics, telecommunications, aerospace, machinery manufacturing, and daily life. It has now become a fine chemical industry with extremely promising development prospects. With the development of the automotive industry, the development and application of high-performance and high-quality automotive adhesives have increasingly attracted people's attention. Adhesives have special functions and practical values and are widely used in automotive production.
