Redispersible polymer powder is mainly used in: interior and exterior wall putty powder, tile adhesive, tile grouting, interface agent, exterior insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproofing mortar, dry mix mortar. In the mortar, the purpose is to improve the brittleness, high elastic modulus and other weaknesses of traditional cement mortar, and to give the cement mortar better flexibility and tensile bonding strength to resist and delay the occurrence of cracks in the cement mortar. Since the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between aggregates and blocks some pores in the mortar. Therefore, the hardened modified mortar has better performance than cement mortar. There is a big improvement.

When the dry mortar is added to the water and stirred, the rubber powder particles are dispersed into the water under the action of the hydrophilic protective colloid and mechanical shearing force. The time required for the dispersion of the normal dispersible polymer powder is very shot. For example, in the dry-sprayed concrete repair mortar, the dry mortar with Redispersible Polymer Powder and the water are sprayed only at the end of the nozzle for about 0.1s. To the construction surface, this is sufficient to fully disperse and film the redispersible powder.
