Redispersible polymer powder (RDP)

Redispersible polymer powder (RDP)

Redispersible polymer powder (RDP) is a water-soluble polymeric material commonly used as an adhesive, binder and thickener in the construction, paint and other industries. RDP is made from synthetic resin emulsions that have been spray dried into a fine powder form. The powder particles are highly dispersible and easily redispersed in water, making it a versatile and convenient material for a variety of applications.

The main features of RDP include.

High adhesion: RDP provides excellent adhesion to a variety of substrates, including concrete, mortar and plaster.

Flexibility: RDP enhances the flexibility of cementitious materials, making them less prone to cracking and deformation.

Water resistance: RDP improves the water resistance of cementitious materials, reducing the risk of water damage and corrosion.

Workability: RDP enhances the workability of cementitious materials, making them easier to spread and handle.

Durability: RDP enhances the durability of cementitious materials, making them more resistant to wear and tear.

RDP is widely used in the construction industry as a key component in cementitious materials such as tile adhesives, self-leveling compounds, exterior insulation and finishing systems (EIFS), and repair mortars. It is also used in the paint and coatings industry as a thickener and binder for water-based formulations.

In summary, RDP is a versatile and high-performance polymeric material with a wide range of applications in various industries. Its unique properties, such as high adhesion, flexibility, water resistance, workability and durability, make it an essential ingredient in many construction and paint formulations.
