The development history of foreign waterproof and oil repellent agents

At first, people sorted out the fabrics with silicon silicon, which could only give the fabric waterproof. Waterproof fabrics were suitable for raincoat materials, but oil -proof, pollution -resistant, and washing resistance were poor.

In 1950, DuPont of the United States took the lead in inventing and patenting tetrafluoroethylene emulsion as a waterproof and oil-repellent agent for fabrics; in 1952, 3M Company of the United States developed a fabric finishing agent with chromium perfluoroxitate complex as the main component. It was replaced by the Scotchguard series of fluorine-containing acrylate fabric finishing agents with better performance; in the 1960s, Japan and Western Europe also successfully developed similar products; in the 1970s, research types showed diversity, such as organofluorine-modified polybutadiene , silicone-containing organofluorine waterproofing and oil-proofing agents, fluorinated polyurethane, etc.; due to environmental protection requirements in the 1980s, the German Hoechst Company developed a water-soluble fluorinated polyurethane waterproofing and oil-proofing agent. This product is environmentally friendly and It is less harmful to the human body and has lower cost; the Asahi Guard fluorine waterproof and oil repellent agent developed by Japan’s Daikin Industrial Co., Ltd. in the 1990s has low-temperature baking properties. At present, the major international companies that produce waterproof and oil-proof products and their product names are: Teflon from DuPont in the United States, Scotchguard from the American 3M Company, Asahi Glass AG from Japan, and Daikin Union.
