REDISPERSIBLE POLYMER POWDERS

DESCRIPTION

Redispersible polymer powder

Synonyms : RPP, polymer powder, polymer additive, RDP

Redispersible polymer powder (RPP) is a polymer capable, when mixed with water, to redisperse, again form aqueous polymer dispersions, which, as a result of curing, form a continuous polymer film, contributing to high water-holding capacity, adhesion and workability of dry building mixtures. 

Production method

The redispersible powder is obtained by spray drying a latex emulsion. To prevent the latex particles from sticking together during production and when diluted with water, polyvinyl alcohol is used. RPP (dry latexes) are usually produced on the basis of: polyvinyl acetate, copolymers of vinyl acetate with ethylene, copolymers of vinyl acetate with vinyl versatate, as well as acrylic polymers.

Properties

After mixing the dry mixture with water, the powder goes into dispersion and after drying forms a film. The film increases adhesion and elasticity, however, the more adhesion, the less elasticity and vice versa. Accordingly, powders are divided into rigid ones with high adhesion, highly elastic with low adhesion, and medium elastic with normal adhesion. In some powders, water repellents are added, imparting hydrophobic properties to the system.

Application area

Redispersible polymer powders are used in the manufacture of products such as:

- Tile adhesives; 

- Plasters; 

- Putties;

- Repair compositions; 

- Waterproofing; 

- Self-leveling floors, etc.

Redispersible Polymer Powder

CAS:-78-8

 

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:

1. 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;
2. 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;
3. 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;
4. 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.
