RDP for crack-resistant mortar is a powder binder made by spray-drying a special emulsion (polymer).
This powder can be quickly dispersed into an emulsion after contact with water, and has the same properties as the initial emulsion.
That is, a film can be formed after the evaporation of water.This film has high flexibility, high weather resistance and high adhesion to various substrates.
In addition, the latex powder with water repellency can make the mortar have good water resistance.
RDP mainly plays a role in the later stage to maintain the firmness of the building.
