Redispersible Polymer Powder Redispersible Polymer Powder is the most important binder in cement-based, gypsum-based dry powder materials. Redispersible Polymer Powder is a spray-dried powder of polymer emulsion. Redispersible Polymer Powder is re-emulsified with water and has the same properties as the original emulsion, that is a film can be formed after water evaporation. This film has high toughness, weather resistance and adhesion to a substrate. In addition, the latex powder with hydrophobic properties can improve the waterproof performance of the waterproof mortar. Performance of Redispersible Polymer Powder in dry mortar: Improve the adhesion of dry mortar to various substrates and ensure the weather resistance of mortar bond strength under various conditions of use. For example, to improve the bond strength between mortar and EPS board, EPS particles, concrete walls and brick walls in the thermal mortar; Reduce the elastic modulus of the materials, improve the elasticity and flexibility of the materials. The material can withstand certain substrate deformation, external force impact, temperature difference deformation, and freeze-thaw deformation. If Redispersible Polymer Powder can significantly improve the dynamic anti-cracking of the putty and the heat aging resistance of the tile adhesive, the impact resistance of the EPS board insulation system; Redispersible Polymer Powder can reduce the water absorption of the material, the special hydrophobic latex powder effect is more obvious. Reduce water and damage caused by water to the molded mortar; Some types of Redispersible Polymer Powder can improve the sag resistance and fluidity of the mortar, in order to improve the construction performance of the mortar.

ZHUOJUN® redispersible polymer powders are free flowing white powders obtained by spray drying macromolecular copolymer dispersions under carefully defined conditions. They are mainly used improve cohesion, adhesion, flexibility and workability in constructions especially in dry-mix mortar. Typical Applications - Tile adhesives - Tile grout - Wall putty - External insulation and finish systems (EIFS) - Cement, lime or gypsum-based finished dry-mix mortar - Self-leveling flooring compounds - Repair mortars and crack fillers - Cement-based plasters - Gypsum fillers
ZHUOJUN redispersible polymer powders are produced by spray-drying special water-based emulsion and are mostly based on vinyl acetate-ethylene. They dissolve in water easily and quickly forms emulsion. Their chemical properties are the same as original emulsion completely. They have excellent flexibility in low temperature. The RDP powders can glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.
The super-softening property of Redispersible Polymer Powder (RDP) can improve the flexibility of cement-based materials while guarantees other work performances. In this study, the influences of different mixing amounts of RDP on the compressive strength, flexural strength, flexural compression ratio and bonding strength of sulphoaluminate cement mortar were investigated. The microscopic morphological structure of RDP-modified sulphoaluminate cement mortar was also observed through SEM to analyse the influence mechanism. Results show that, with the mixing amount of 2.0%, the compressive strength of cement mortar was improved. This mixing amount also increased the 28d flexural strength to 8.21 MPa (5.0% improvement) and 14d bonding strength to 5.6 MPa (27.3% improvement). Addition of more RDP resulted in the increase in flexural compression ratio because the powder particles formed water-insoluble continuous polymer colloidal film in hardened paste. This film generated a network with cement dydration products throughout the paste, consequently promoting the flexibility of cement.
The redispersible polymer powder product is white or off white flowable powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid. Purpose: ceramic tile adhesive bonding mortar of external wall external insulation system external wall external insulation system plastering mortar tile jointing agent self flowing cement mortar flexible putty for inner and outer walls flexible crack resistant mortar
Redispersible Polymer Powder (RDP) is a free-flowing, white powder used in construction as a vital component in cement-based systems. It enhances cohesion, flexibility, and water resistance, improving mortar and adhesive properties. Upon mixing with water, it forms a film, enhancing bond strength and durability in various building applications like tile adhesives and renders.
