Product Features of Haozhou City's Redispersible Latex Powder
The research on redispersible rubber powder began in 2000 with the German company's polyvinyl acetate redispersible latex powder and Japan's powdered latex. After World War II, the severe shortage of labor and construction resources forced Europe, especially Germany, to use various powder building materials to improve construction efficiency. In the late 1990s, Germany's Hoechst Company and Wacker Chemical Company began the industrial production of redispersible latex powder. . At that time, redispersible latex powder was also mainly polyvinyl acetate type, which was mainly used for woodworking adhesive wall primers and cement-based wall materials. However, due to the limitations of rubber powder such as high minimum film-forming temperature, poor water resistance, and poor alkali resistance, its use is greatly restricted.
With the successful industrialization of emulsions and/or other emulsions, in the last century, redispersible latex powder with a minimum film-forming temperature of ℃ and good water resistance and alkali resistance was developed. After that, its application in It has been widely promoted in Europe, and the scope of use has gradually expanded to the fields of various structural and non-structural building adhesives, dry-mixed mortars, modified wall insulation and finishing systems, wall smoothing glue and sealing plaster, powder coatings, and construction putty. .
