Redispersible polymer powder (RDP) is a type of polymer powder made by spray-drying an aqueous emulsion of a polymer. The powder consists of polymer particles that are coated with a protective surface treatment, such as a fatty acid, which allows the particles to disperse in water and form a stable emulsion. RDP is widely used in construction materials, such as mortars, tile adhesives, and grouts, to improve the mechanical properties and workability of the materials.

RPP is typically made from a variety of polymers, including vinyl acetate-ethylene (VAE), vinyl acetate-butyl acrylate (VAc-BA). The choice of polymer depends on the desired properties of the final product. For example, VAE RDP are often used in tile adhesives and exterior insulation finishing systems (EIFS) because they provide good water resistance and high flexibility and also used in mortars and cement-based products because they provide good adhesion and improved impact resistance.

The properties of RDP can be customized by adjusting the type and amount of polymer used, as well as the surface treatment of the particles. Some common properties that can be improved by the addition of RDP include water resistance, adhesion, flexibility, and workability. Additionally, RDP can improve the durability and lifespan of construction materials by reducing cracking and increasing the resistance to weathering and environmental stresses.

What Is Redispersible Polymer Powder Used For?

Redispersible polymer powder (RDP) is a versatile and widely used polymer additive in the construction industry. RPP improves the mechanical properties and workability of construction materials, as well as their durability and resistance to environmental stresses in a variety of applications, including:

Tile adhesives:

RDP improves the adhesion of tiles to substrates, as well as the flexibility and water resistance of the adhesive.

Cement-based mortars:

RDP enhances the workability and flexibility of cement-based mortars, making them easier to apply and more durable.

Exterior insulation finishing systems (EIFS):

RDP improves the adhesion, water resistance, and flexibility of EIFS, which are used to insulate and finish exterior walls.

Self-leveling compounds:

RDP improves the flow and leveling properties of self-leveling compounds, which are used to level and smooth out uneven surfaces.

Repair mortars:

RPP enhances the adhesion and workability of repair mortars, which are used to repair and fill in cracks and holes in concrete and masonry.

Gypsum-based products:

RPP improves the setting time, workability, and water resistance of gypsum-based products, such as joint compounds and plaster.

Grouts:

RPP improves the adhesion, flexibility, and water resistance of grouts, which are used to fill gaps between tiles or other building materials.
