It has extremely outstanding waterproof performance, good bonding strength, increases the elasticity of the mortar and has a longer open time, gives the mortar excellent alkali resistance, and improves the adhesion/adhesion, flexural strength, plasticity and resistance of the mortar. In addition to grinding performance and workability, it has stronger flexibility in flexible anti-cracking mortar.
The role of redispersible latex powder:
The redispersible latex powder is dispersed into a film and acts as a reinforcing agent as the second adhesive;
The protective colloid is absorbed by the mortar system (will not be destroyed by water after film formation, or "secondary dispersion");
The film-forming polymer resin is distributed throughout the mortar system as a reinforcing material, thereby increasing the cohesion of the mortar;
The role of redispersible latex powder in wet mortar:
Improve construction performance;
Improve flow performance;
Increase thixotropy and sag resistance;
improve cohesion;
extended opening hours;
Enhances water retention.
The role of redispersible latex powder after the mortar is cured:
Improve tensile strength;
Increase the bending strength;
reduce the elastic modulus;
Improve deformability;
Increase the density of the material;
Increase wear resistance;
Improve cohesive strength;
Reduce the carbonization depth;
Reduce the water absorption of materials;
Make the material have excellent water-enhancing properties (adding water-enhancing rubber powder)
