MFFT is the lowest temperature which allows polymer particles in emulsion have enough activity for intercoagulation and continuous film forming. During films forming, the polymer particles have a closer arrangement. To form a continuous film, besides good dispersion emulsion, there is also the requirement of polymer particles deforming (which shows the pressure between particles forced by hydraulic pressure). Closer the particles be, stronger the pressure would become.

Extend the work time and improve water retention performance to ensure the hydration of cement and improve workability;

The glass-transition temperature refers to the temperature at which polymers will be converted from an elastic state to a glassy state, expressed by Tg. When the temperature is higher than Tg, the material is rubber-like in behavior and generates the elastic deformation under load;

The roles that redispersible polymer powder plays in mortar can be considered as follows. First, after water added into mortar, the powder particles will get dispersed in water and quickly form a film under the action of hydrophilic protective colloid and mechanical shear force

After redispersible polymer powder is added into cement mortar, the tensile strength and flexural strength of mortar will be significantly improved, while the compressive strength won’t get significantly improved, even declined.

It is a copolymer of vinyl acetate and ethylene. It used to promote adhesion and flexibility under a wide variety of climate conditions and shows universal properties in many dry-mortar applications. Improves pot life, workability, w

 Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate and ethylene. It dissolves in water easily and quickly forms emulsion.

Join in the mortar redispersible polymer powder mortar, the ratio of flexural tension and compression ratio are increased, indicating that the brittleness of mortar is greatly reduced and the toughness is improved greatly, thus improves the crack resistance of mortar.

(RDP) MANUFACTURERSREDISPERSIBLE POLYMER POWDER is a free-flowing, white powder obtained by spray drying of an aqueous vinyl acetate-ethylene copolymer dispersion. Redispersible polymer powders are polymer emulsions which have been converted by spray drying (atomizing the aqueous polymer dispersions in a stream of hot air) to free flowing powders.
