With the increasingly stringent global environmental regulations and the increasing public attention to environmental protection, various environmentally friendly adhesives have gradually become the mainstream of the market, and water-based adhesives and hot melt adhesives are sought after.

Water-based products are popular

    Yang Xu, vice chairman and secretary-general of China Adhesives and Adhesive Tape Industry Association, said that in 2018, my country sold 7.87 million tons of adhesive products, with sales of 98.78 billion yuan. Among various adhesive products, the sales volume of water-based adhesives reached 4.619 million tons, with sales reaching 33.1 billion yuan, becoming the most mainstream variety in the industry.

  According to Murakami, the vice president of the Japanese Adhesive Industry Association, environmentally friendly adhesive products such as water-based adhesives and formaldehyde resins have become the mainstream in the Japanese market in the past two years; solvent-based adhesives have become one of the products with the lowest market share, and the market share is still low. Decrease every year.

    Kim Hyun Joong, a technical consultant and director of the Korea Industry Association, said that in 2018, the sales of Korean adhesives reached 679,000 tons, with sales of 2.08 billion US dollars. Among these products, water-based adhesives account for 36.2% of all products, while solvent-based adhesives account for only about 4%.

    Shi Renzheng, chairman of the Synthetic Resin Adhesive Industry Association in Taiwan, China, also said that in 2018, Taiwan's adhesive sales reached 505,000 tons, and sales reached 37.16 billion Taiwan dollars. Among them, water-based adhesives accounted for 38% of the total sales, reactive adhesives accounted for 22.4%, pressure-sensitive adhesives accounted for 13.3%, and solvent-based adhesives accounted for only 7.4%.

    "Take the production of shoes as an example. If traditional solvent-based adhesives are used, each pair of shoes consumes 13.3 grams of chemical substances and produces 10.97 grams of VOCs. After switching to water-based adhesives, only 6.1 grams of chemical substances are consumed and 0.06 grams of VOCs are produced. The latest water-based polyurethane adhesive only consumes 3 grams of chemicals and no VOCs are produced. This improvement will inevitably be widely welcomed both for consumers and shoe manufacturers." Shi Renzheng said.


Environmental protection policy forces industry transformation

    The environmental protection of adhesive products is inseparable from the tightening of environmental protection policies in various countries and regions.

    Philip Bruce, secretary general of the European Adhesives and Sealants Industry Association, said that Europe has established strict environmental standards to promote the sustainable development of various industries. At present, the European adhesive market focuses most on how to make products meet the requirements of circular economy.

    According to Murakami, the Japanese Adhesives Industry Association has also introduced non-formaldehyde product certification (F4 certification), as well as VOCs recommended consistency standards, and launched a negative list of food packaging adhesives, household product packaging guidelines, labor safety investigations, etc., to ensure that the adhesive is in During production and use, there is no harm to the human body and the environment.

    Shi Renzheng said that the Taiwan region has launched environmentally friendly product certification and issued products that do not contain metals such as lead, chromium, mercury, cadmium, arsenic, and antimony, as well as products with extremely low levels of harmful substances such as formaldehyde, triphenyltin, and tributyltin. Green logo certification. At present, many clothing brands such as Levi's, HM, ZARA, Uniqlo, Adidas, Lining, Nike, etc., which are producing in Taiwan, have pledged to completely stop the use of adhesives containing harmful chemicals by 2020.

    Yang Xu said that since September 2017, my country has also issued a number of environmental protection policies and regulations. "In 2018 alone, 13 new national mandatory standards, recommended standards for the chemical industry, and standards for building materials related to the adhesive and tape industries were implemented." Yang Xu said.

    "Under the high pressure of environmental protection, enterprises with standardized operations are ushering in development opportunities, and their profits have increased significantly; those enterprises with low environmental protection investment are increasingly difficult to survive in the current environment. Accordingly, the product quality of the entire industry has been continuously improved. The proportion of high-quality, environmentally-friendly products has continued to increase." Yang Xu said.

Technology upgrade is the top priority

    "Although the current use ratio of water-based adhesives and hot-melt adhesives continues to increase, the use of solvent-based adhesives is still inevitable in some special fields. The adhesive industry still needs technological breakthroughs to allow environmentally friendly adhesive products to fully cover the demand areas. "Jin Xianzhong said.

    I, Jin Xianzhong, give an example that the automobile industry has always been a pillar industry of Korea. With the market's increasing requirements for the lightweight of various products, the amount of adhesives is increasing in the fields of automobile bodies, power batteries, and parts. At present, the amount of adhesives used in the Korean automobile industry has reached five times that of five years ago. With the market's requirements for large size and light weight of mobile electronic terminals, the market's demand for adhesives will continue to increase in the future. This also means that the adhesive industry needs to further improve the environmental protection level and technical level of products to ensure the continuous reduction of total pollutant emissions.

    China's adhesives and adhesive tape industry is also facing a series of new challenges: the contradiction of overcapacity in the industry is prominent, environmental protection requirements are becoming stricter, global oil prices are fluctuating, companies are forced to limit or stop production, and chemical companies have heavy relocation tasks. Sino-US trade frictions have intensified, the prices of raw materials have risen too fast, and market competition has become increasingly fierce.

    I, Yang Xu, said that under this situation, the focus of adhesive companies is to improve their technical level, vigorously develop water-based adhesives, new hot melt adhesives, and solvent-free, UV-curable, high-solids and other environmentally friendly types. Type product.
