High-performance adhesive will become the new favorite

The Beijing World Adhesives Conference held in Beijing from October 20th to 22nd can be seen: With the idea of ​​protecting the environment and cherishing resources, people are increasingly immersed in the people's mind, and the environment-friendly properties such as high solid content, solvent-free, water-based, and light-curing adhesives. Will be more and more attention, high-performance environmentally friendly adhesive will become the new darling of the market.

In recent years, China's adhesives and sealants industry has made great progress, and its application range has also expanded to include construction, automotive, electronics, household appliances, carpentry, paper products and packaging, footwear, transportation, aerospace and medical and health care. And other fields.

At present, the demand for adhesives in the domestic market is diversified. The annual growth rate of general-purpose adhesives is 8%, the annual growth rate of high-performance, high-quality adhesives is 12%, and the annual growth rate of special adhesives is more than 20%. Therefore, adhesives manufacturers should increase investment in science and technology, and actively develop high-performance, high-quality new products, such as super adhesive strength acrylate pressure sensitive adhesive and tape, modified PVAc emulsion, silicone PSA and adhesive tape, modified ring Oxygen resin adhesives, water-based neoprene adhesives, polyester and polyamide hot melt adhesives, high-grade medical pressure-sensitive adhesives and products, epoxy structural adhesives for electronic and aerospace applications, and new modified epoxy resin adhesives Waiting to adapt to new needs.

In China's adhesive industry, the phenomenon of oversupply of general-purpose middle and low-end products is still very serious, and the market competition is fiercer. These products include: Acrylic pressure sensitive adhesives for BOPP film and paper base; EVA hot melt adhesives for book binding (medium and low speed), hot melt pressure sensitive adhesives and labels, neoprene, common type Silicone sealant and so on. The demand for high-performance, high-quality and specialty adhesives and sealants is due to factors such as high technical content, complex production processes and equipment, and high quality requirements, which require import from abroad.

At present, some of the main raw materials and related auxiliaries used in the production of adhesives in China are in short supply and cannot be produced or the quality and performance of the products sometimes fail to meet the requirements of users, such as EVA, SIS, and PA for the production of hot-melt adhesives and hot-melt pressure-sensitive adhesives. Resins, TPU resins for footwear, etc., are imported from foreign countries in large part or in part, and this needs to be further accelerated. (Source: China Chemical News)
