CAS: 24937-78-8
RDP is based on synthetic polymer, which on mixing with water obtains suction adhesive qualities, fit for adhesive bonding several different construction materials, making this powder to bring about a significant change in the construction being much more resilient and durable for mortars and adhesives. RDP is different from other products in this field because it has exceptionally good adhesion and flexibility, an important addition needed for enhancing construction and restoration projects since its inception in the 1980s and its rapidly growing global spread as a crucial ingredient for quality architectural projects requiring strength and durability.
An interesting fact about RDP is that it is a material that reactivates when in contact with water, which allows it to be adjusted to the conditions for application on site.

Physical Properties of Redispersible Polymer Powder (RDP)
Redispersible Polymer Powder appears as a fine, white powder with a smooth, homogenous texture. It is odorless and water-soluble, which allows for even dispersion in mixtures. Its composition enables rapid redispersion, making it ideal for applications where adhesion and cohesion are crucial.
Use in Construction Field
The redispersible polymer powder is used in the construction segment mostly for formulating mortars, tile adhesives, grout compounds, and wall coatings. Improved cohesion and flexibility in those materials help the structures withstand changes of temperature and humidity, hence extending the serviceability of the construction works.
Other Applications
● Gypsum-Based Products: RDP is widely used in gypsum plasters and fillers to improve workability, adhesion, and surface cohesion. It helps to prevent cracking and enhances the finishing quality of gypsum-based products.
● Cement-Based Waterproofing: RDP is used in waterproofing, to improve the water resistance, flexibility and durability of cement-based formulations suitable for basement, swimming pool and bathroom coatings.
● Self-Leveling Compounds: Self-leveling floor compounds utilize RDP for its benefits of increased flow, adhesion and setting properties, producing smoother and more durable surfaces.
● Exterior Insulation and Finishing Systems: EIFS has many applications of RDP, which improve flexibility and adhesion to building surfaces thereby contributing to energy efficiency and improvement in structural protection.
