Redispersible polymer powder is a powder of organic binder made by spray drying a special emulsion (high molecular polymer). This powder can be quickly re-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 water evaporates. This film has high flexibility, high weather resistance and high adhesion to various substrates.
RDP powder is an essential material for dry-mix mortar. It can improve performance of the mortar, increase strength of mortar, increase bonding strength of the mortar and various substrates, and improve flexibility and deformability of mortar, compressive strength, flexural strength, abrasion resistance, toughness, and bonding Power and water retention capacity, constructability.

With a very outstanding bonding strength, improve the flexibility of mortar and have a long opening time, give mortar excellent alkaline resistance, improve the mortar adhesion, adhesion, strong folding resistance, waterproof, plasticity, wear resistance and construction, in the flexible crack resistance mortar has more strong flexibility.
To be stored in a cool and dry place, the recommended service life is six months, in summer as early as possible.If stored in a high temperature, wet place, it will increase the probability of agglomeration.
After opening the bag, please use it as much as possible, otherwise the bag should be sealed to avoid absorbing moisture from the air.
