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.

- Improved water retention capability and open time
Honghai brand Redispersible polymer powder(RDP) product are widely used in the construction industry-ceramic tile slurry, dry mixed mortar,crack filler, tile adhesive,self-leveling mortar, thermal insulation mortar,skim coat,putty powder, tile grouts,tile joint filler,decoration mortar,coating glue, cement-based plastering mortar and cement-based ceramic tile adhesive.
RDP For Wall putty
Water retention: maximized water content in slurry.
Anti-sagging: when spreading a thicker coat corrugation can be avoided.
Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.
RDP For Exterior Insulation and Finish System ( EIFS )/ETICS
Good wetting ability for EPS board and substrate.
Reduced air entrancement and water uptake.
RDP For Self-leveling
Protection from water exudation and material sedimentation.
No effect on slurry fluidity with low viscosity
HPMC, 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
