Redispersible polymer powders (RDP) are commonly used in the construction industry as additives in cement-based mortar formulations. These polymers enhance the performance of mortar by improving properties such as adhesion, flexibility, water resistance, and workability. When formulating cement-based mortar with RDP, it’s essential to consider several factors to achieve the desired properties. Here are some […]

The main Redispersible polymer powders currently used in the market are: vinyl acetate vinegar and ethylene copolymer latex powder (VAe/E), ethylene and vinyl chloride and lauric acid ethylene vinegar ternary copolymer latex powder (E/VC/VL), vinyl acetate vinegar and Ethene and higher fatty acid vinyl ester ternary copolymer latex powder

The minimum film-forming temperature refers to the minimum temperature at which polymers form a continuous film, expressed by MFT. If the cement hydration temperature is below this value, the energy supplied will not be enough to start film formation.

The first step in the production of redispersible polymer powders is the production of polymer dispersions, also known as emulsions or latexes.  the water-emulsified monomers (stabilized by emulsifiers or macromolecular protective colloids) react with initiators to start emulsion polymerization.
