Factory Redispersible Polymer Powder Rdp for Mortar Dry Powder Coating

Product Description

Redispersible polymer powder(RDP) produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE),

and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by

coalescence of individual polymer particles. The film acts as an organic binder, to glue together different substrates, reinforce

mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.

Redispersible polymer powder(RDP) Key properties

- Increase adhesive/cohesive strength

- Higher flexural strength

- Excellent rheology

- Improved workability

- great durability and abrasion resistance

- Improved water retention capability and open time


RDP Application

RDP For Self-leveling

Protection from water exudation and material sedimentation.

No effect on slurry fluidity with low viscosity

RDP, while its water retention characteristics improve the finish performance on the surface.

RDP For Crack Filler

Better workability: proper thickness and plasticity.

Water retention ensures prolonged work time.

Sag resistance: improved mortar bonding ability.

RDP For Tile Adhesives

Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.

Good water retention: prolonged opening time will make tiling more efficient.

Improved adhesion and sliding resistance: especially for heavy tiles.

RDP For Dry mix mortar

Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.

Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.

RDP For Cement Plaster

Increased water demand: increased open time, expanded spry area and more economical formulation.

Easier spreading and improved sagging resistance due to improved consistency.
