Redispersible Latex Powder Anti-cracking Mortar Additive CAS 24937-78-8
JF REDISPERSIBLE POLYMER POWDER Product Introduce:
Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., powder bonded after spray drying It uses polyvinyl alcohol as a protective colloid. This kind of powder can be quickly redispersed into emulsion after contact with water. Because redispersible latex powder has high bonding ability and unique properties, such as: water resistance, construction and heat insulation, etc., their The scope of application is extremely wide.

Development History Of Redispersible Latex Powder:
The research on redispersible rubber powder began in 1934 with the polyvinyl acetate redispersible latex powder of I.G.Farbenindus AC Company in Germany and the powdered latex of Japan. The severe shortage of labor and construction resources after World War II forced Europe, especially Germany, to adopt various powdered building materials to improve construction efficiency. In the late 1950s, Germany's Hearst Company and Wacker Chemie started the industrialization of redispersible latex powders. Production.
At that time, the redispersible latex powder was also mainly of polyvinyl acetate type, which was mainly used for woodworking glue, wall primer and cement-based wall materials. However, due to the limitations of PVAc rubber powder's high minimum film forming temperature, poor water resistance, and poor alkali resistance, its use is greatly restricted.
With the successful industrialization of VAE emulsions and VA/VeoVa emulsions, in the 1960s, redispersible latex powders with a minimum film-forming temperature of 0°C and good water resistance and alkali resistance were developed. The application has been widely promoted in Europe, and the scope of use has gradually expanded to various structural and non-structural building adhesives, dry-mixed mortar modification, wall insulation and facing systems, wall troweling glue and sealing plaster, The field of powder coatings and construction putty.
