Redispersible powders have become an integral component in the construction industry, especially when it comes to enhancing the properties of materials like tile adhesives, mortars, and other cementitious systems. These powders, when mixed with water, redisperse into their original polymer emulsion form, offering a myriad of benefits to the final product. Let's delve into the different types of redispersible powders and their unique characteristics.

At its core, a redispersible powder is a polymer emulsion that has undergone spray drying. This process transforms the liquid emulsion into a free-flowing powder form. When this powder is mixed with water, it returns to its original emulsion state, allowing it to impart its beneficial properties to the mixture.
One of the primary reasons for the inclusion of redispersible powders in construction materials is their ability to improve rheological properties. This means that they can modify the flow and spread of materials, making them easier to apply and ensuring a smoother finish.
Water resistance is another crucial attribute enhanced by these powders. By incorporating them into the mix, materials like tile adhesives become less susceptible to water damage, ensuring longevity and durability.
Furthermore, bond strength is significantly improved. This ensures that tiles, for instance, adhere more securely to their substrates, reducing the risk of detachment or failure.
The market currently offers several types of redispersible polymer powders. Among the most prevalent are:
Apart from the primary types of redispersible powders, there are other components that play a role in their efficacy. Polyvinyl alcohol, for instance, is often used as a protective colloid during the spray drying process. This ensures that the powder remains free-flowing and doesn't clump together.
Redispersible powders have undeniably revolutionized the construction industry. Their ability to enhance properties like bond strength, water resistance, and rheological characteristics makes them indispensable in modern construction materials.
For those in the concrete admixture industry, sourcing high-quality raw materials is paramount. At Bisley International, we pride ourselves on supplying top-tier products to meet your needs.

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.
