Driven by the automotive industry’s demand for weight reduction and improved fuel efficiency, the automotive industry’s demand for adhesives continues to grow. The automotive industry is increasingly inclined to use more lightweight materials, such as plastics, composites and aluminum alloys, which ultimately require the use of adhesives. Therefore, these are the main factors driving the growth of the global adhesive market. Automotive adhesives are used in a wide range of applications, including body-in-white, spray shops, powertrains, and assembly.
Automotive interior adhesive
- Neoprene decorative adhesive. Neoprene is the earliest developed synthetic rubber with reversible crystallinity, high bonding strength, high tensile strength and elongation, excellent weather resistance and heat resistance. The prepared adhesive can be cold-cured at room temperature and has bonding. High strength, high initial adhesion, good resistance to medium properties, wide bonding range, etc. However, the long-term storage of neoprene will release hydrogen chloride, promote its hydrolysis, and will corrode the metal. Therefore, it is necessary to add magnesium oxide and light zinc chloride. In order to prevent the aging of the adhesive, an antioxidant can also be added.
- SBS decorative adhesive. It has the characteristics of high strength, good toughness, fast curing and low temperature resistance.
