RDP powder, or redispersible polymer powder, is a key additive that significantly enhances the performance of modern construction materials. It is an essential ingredient for the formulation of tile adhesives, mortars, self-leveling compounds and repair mortars. It also helps to reduce the cost and environmental impact of construction.
Adding VAE RDPs to cementitious mixtures significantly improves their water retention, open time and workability. In addition, it imparts flexibility and anti-sagging characteristics to the finished material. Typical applications include the formulation of cement-based construction materials, such as tile adhesives, grouts, finishing plasters, troweling compounds and repair mortars, and sealing slurries.
These properties make VAE RDPs particularly well-suited for use in construction, especially for high-performance products like EIFS and waterproofing systems. The improved adhesion they provide means that materials and components are less likely to delaminate or crack, even in areas subject to repeated moisture changes.
In addition, VAE RDPs are easy to handle and transport. They are not prone to freezing or coagulation, and their dry form allows for considerable cost savings in transportation and storage costs, as compared to liquid polymers. They also tend to be safer to handle and possess lower odor levels than some other construction additives. This makes them an excellent choice for green building projects, as well as environmentally conscious initiatives.
