  • Inquiry


It is a type of re-dispersible emulsion powder of terpolymer copolymerized with VAC/VEO/VAE. It is the powder formed after spraying and drying. It dissolves in water easily and quickly forms emulsion. Its chemical properties are the same as original emulsion completely. It has good adhesive strength, excellent resistance to alkaline water, weather resistance, freezing-thawing resistance and excellent flexibility in the low temperature.

1 Soft emulsion powder, dispersed in water to increase the adhesion between mortar and its substrates and improve the mechanic property and construction of mortar.

2 It can improve the mortar mechanical properties of mortar, adhesion/adhesiveness, breaking strength, plasticity, wear-resisting performance and constructability of mortar, and it has more strong flexibility in flexibility anti-crack mortar.

3 Improve the bending strength and folding strength of mortar. The polymer film formed by the redispersible powder is very flexible. Film is formed on the clearance and surface of cement mortar particles to form flexible connection. Thus the brittle cement mortar becomes elastic. Mortar with redispersible powder is several times higher than normal mortar in tensile and folding resistance.

4 Improve the bonding strength and cohesion of mortar.

As an organic adhesive, the redispersible powder can form high tensile strength and adhesion strength on different substrates. It plays an important role in the adhesion between mortar and organic materials (ESP, extruded plastic foam plate) and smooth surface substrate. As a reinforcing material, the film forming polymer powder is distributed in the whole mortar system to increase the cohesion of mortar.

5 Improve mortar impact resistance, durability, wear resistance.

Rubber powder particles filled the cavity of mortar, mortar density increased, improve the wear resistance. Under the action of external forces will be relaxed without being destroyed. Polymer film can exist in the mortar system permanently.

6 Improve the weather resistance of mortar, freeze – the resistance, prevent mortar cracking.

The redispersible powder is a thermoplastic resin with good flexibility. It can make the mortar deal with the change of external cold and hot environment and effectively prevent the mortar from cracking due to the change of temperature difference.

7 Improve mortar hydrophobicity, reduce water absorption.

Redispersible powder in the mortar cavity and surface film, the polymer film will not be twice dispersed after water, prevent the invasion of water, improve the impermeability. It has excellent hydrophobic effect.

8 Improve the workability of mortar construction.

The particles of polymer rubber powder have lubrication effect. There is a lubrication effect between the particles of polymer rubber powder, which enables the mortar components to flow independently. At the same time, rubber powder has an induction effect on the air, which gives the mortar compressibility and improves the construction and workability of the mortar.
