Construction Additive Use Redispersible Single Polymer ...
According to recent findings from Google searches, the use of redispersible polymer powders significantly enhances the performance of construction materials. Specifically, these powders increase adhesion, flexibility, and water resistance in materials like mortar and plaster.
Product Description
Redispersible polymer powder (RDP) is produced by spray-drying a special water-based emulsion, mainly based on vinyl acetate-ethylene (VAE). This process yields a free-flowing organic polymer powder that can be redispersed in water. After water evaporation, it forms a film due to the coalescence of individual polymer particles. This film serves as an organic binder, bringing together various substrates, reinforcing mortar structure, and providing enhanced adhesion at the cement or gypsum-based dry mixed mortar substrate interface.

RDP Applications
Honghai brand Redispersible polymer powder (RDP) products are widely used in the construction industry for a variety of applications including 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: prevents corrugation when spreading a thicker coat.
Increased mortar yield: HPMC can increase the mortar volume depending on the weight of the dry mixture and appropriate formulation.
RDP for Exterior Insulation and Finish System (EIFS) / ETICS
Improved adhesion: 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. Ensures slurry fluidity with low viscosity HPMC while improving finish performance on the surface.
RDP for Crack Filler
Better workability: ensures proper thickness and plasticity. Water retention provides prolonged work time. Enhanced sag resistance improves mortar bonding ability.
RDP for Tile Adhesives
Better workability: ensures lubricity and plasticity of plaster, making mortar application easier and quicker. Good water retention prolongs opening time for more efficient tiling. Improved adhesion and sliding resistance, especially for heavy tiles.
RDP for Dry Mix Mortar
Easy dry mix formula due to cold water solubility: prevents lump formation, ideal for heavy tiles. Good water retention prevents fluid loss to substrates, maintaining appropriate water content in the mixture for longer concreting time.
RDP for Cement Plaster
Increased water demand: longer open time, expanded spray area, and more economical formulation. Easier spreading and improved sag resistance due to better consistency.

RDP/VAE Overview
RDP (Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble redispersible powder. It is a copolymer of ethylene and vinyl acetate, which dissolves in water easily and forms an emulsion quickly. RDP offers strong adhesive and stretching force to improve the workability, flexibility, and water-proofing of the materials. The primary application of this free-flowing white powder, which is spray-dried from polymer emulsion, is in construction dry-mixed mortar. It significantly enhances the dry mortar's adhesion, cohesion, and flexibility.
Key Properties of RDP/VAE
- Increases adhesive/cohesive strength
- Higher flexural strength and flexibility
- Excellent rheology
- Improved workability
- Durability and abrasion resistance
- Improved water retention capability and open time
Application of RDP/VAE
The redispersible polymer powder (VAE) is a versatile material for the construction industry. It can be used in tile adhesives, crack fillers, self-leveling mortars, exterior insulation and finish systems, cement-based plasters, and other construction needs. Adding re-dispersible latex powder to mortars can significantly improve their performance, making them meet various construction demands.
