Dow Chemical Sichuan Company applied for approval to meet the growing demand for water-based coatings-TMPDA-Tetramethylpropylenediamine

After nearly a year of demonstration and preparation, Dow Chemical’s application to invest in Pengshan District, Meishan to establish “Dow Chemical (Sichuan) Co., Ltd.” was approved on August 23 It was approved on the same day, announcing that another overseas Fortune 500 company has successfully settled in Meishan.
In recent years, with the rapid development of my country’s economy for many years, the problem of air pollution has become more and more prominent year by year, especially the large-scale haze weather in recent years, which has caused obvious harm to people’s health. Among them, organic pollutants are one of the main causes of haze. To this end, the Ministry of Environmental Protection and the Sichuan Provincial Environmental Protection Department have successively issued air pollution prevention and control plans such as the “Technical Policy for the Prevention and Control of Volatile Organic Compounds (VOCs) Pollution” and the “Twelfth Five-Year Plan for Air Pollution Prevention and Control in Key Areas” (Sichuan Province Implementation Plan). and policies to encourage the production and sales of water-based, organic solvent-free and low organic solvent-based coatings, inks and adhesives that meet the technical requirements for environmental labeling products. Actively promote the pollution control of volatile organic compounds in surface coating processes in industries such as automobile manufacturing and maintenance, electronic products, household appliances, furniture manufacturing, equipment manufacturing, and wire and cable industries.
Comprehensively increase the use proportion of low-volatile organic content coatings such as water-based, high-solids, powder, and UV-curable coatings to more than 50% in automobile manufacturing companies, more than 30% in furniture manufacturing companies, and 50% in electronic product and electrical product manufacturing companies. %above. “The market demand for high-quality water-based coatings is showing a clear growth trend.” Dow Chemical said.
It is understood that water-based acrylic resin not only has the advantages of stability, weather resistance, light resistance, chemical resistance, etc., but also has the characteristics of anti-corrosion, alkali resistance, low pollution, good construction performance, and safe use. In particular, it avoids organic substances during use. The use of solvent diluents greatly reduces the amount of organic waste gas emissions during use. It is the fastest growing non-polluting paint among water-based paints and is widely used in water-based wood paints, water-based plastic paints and water-based metal paints.
Dow Chemical is a diversified chemical company that drives innovation and creates value through the organic combination of chemistry, physics and biological sciences. With its integrated, market-driven, industry-leading specialty chemicals, high-tech materials, agricultural sciences and plastics businesses, Dow provides customers in approximately 180 countries and regions around the world with a wide range of products and services for packaging, electronics Products, water treatment, coatings and agriculture and other fast-growing markets. With annual sales of approximately US$60 billion, it operates more than 200 factories in 35 countries and regions with more than 6,000 products. It ranked 187th in the Fortune Global 500 list announced on July 20, 2016. .
Dow Chemical said that taking into account the broad demand for water-based coatings in the southwest China market, Dow Chemical (China) Investment Co., Ltd. plans to build a 60,000 tons/year acrylic emulsion project in Chengmei Industrial Park, Meishan City, Sichuan Province. Containing 30,000 tons of low-volatile acrylic emulsion polymer, the products are mainly used in coatings, building materials, non-woven fabrics, printing and dyeing, paper products, pressure-sensitive adhesives, light industry and other fields. It is in line with the policy requirements of the Ministry of Environmental Protection to encourage water-based coatings that meet the technical requirements of environmental labeling products. It can also promote pollution prevention and control in the “Twelfth Five-Year Plan for Air Pollution Prevention and Control in Key Areas” (Sichuan Province Implementation Plan) to comprehensively increase the proportion of water-based use. planning. The process route of this project is a mature, high-efficiency, low-energy consumption acrylic and ester emulsion production process route developed by Dow Chemical. Through years of technological updating and optimization, Dow Chemical currently has the same acrylic ester emulsion production lines in Shanghai and Guangdong. Emulsion production equipment.
It is understood that the project plans to invest 486 million yuan, covering an area of ​​135 acres, and build an acrylic emulsion device of 60,000 tons per year and a low-volatile acrylic emulsion device of 30,000 tons per year. Among them, the first phase investment is US$75 million to build a 60,000 tons/year acrylic emulsion production line. After the project is completed, the average annual sales revenue will exceed RMB 600 million.
