Redispersible polymer powders (RDP) are white, free-flowing powders produced through the spray-drying of polymer dispersions. When mixed with water, these powders can break apart and reproduce individual polymer dispersions that possess the same characteristics as the original. Widely use in tile adhesive, tile grout, wall putty, repair mortars, EIFS mortars, and self-leveling compounds, Rigid RDP enhances the performance of products with improved adhesion, tensile strength, crack resistance, and water retention in construction.
Compared with other types of RDP, Rigid RDP holds minimal elasticity and offers a stronger adhesion. So it is especially suited for products requiring firm adhesion.
Redispersible PolymerPowder(RDP), alsoknown as VAE RDP, is a high-performance additivethat provides essential benefits in constructionapplications. Produced from vinyl acetate-ethylenecopolymer emulsions through a spray-dryingprocess, RDP is a free-flowing, water-dispersiblewhite powder. When integrated into dry mortarformulations, Michem’s VAE RDP significantlyenhances properties such as adhesion to varioussubstrates, cohesion within the mortar matrix, andbonding strength.
MICHEM offers OEM solutions and a tailored formula guide for your specific needs. Also, we offer free sample to help you test.
MICHEM Rigid RDP forms a dense network structure in the cement matrix, which effectively closes the capillary pore channels and reduces the water absorption rate, allowing the material to remain stable in long-term wet environments.
The addition of MICHEM Rigid RDP improves the mortar’s ability to withstand shear stress, resulting in a lower wear rate and higher abrasion resistance, extending the service life of the mortar.
MICHEM Rigid RDP has a high glass transition temperature and does not soften easily at high temperatures.
At the same time, the coefficient of thermal expansion of rigid RDP matches that of concrete, reducing the risk of cracking caused by temperature difference stresses.
Redispersible polymer powder (RDP) is derived from spray-dried polymer emulsion. It retains the properties of the original emulsion upon re-emulsification with water. This enables the formation of a film upon water evaporation, ensuring consistent final performance for your tasks
