what is redispersible polymer(latex) powder?

The redispersible latex powder product is a water-soluble white or almost white flowable powder, a copolymer of f ethyle ethylene and vinyl acetate, and polyvinyl alcohol as a protective colloid.

Because redispersible latex powders have high bonding ability and unique properties, such as: water resistance, construction and heat insulation, etc., their application range is extremely wide.

construction additivies

Performance:
It has outstanding waterproof performance, good bonding strength, increases the elasticity of the mortar and has a longer open time, imparts excellent alkali resistance to the mortar, and improves the adhesion/adhesiveness, flexural strength, plasticity and resistance of the mortar In addition to abrasion performance and workability, it has stronger flexibility in the flexible anti-cracking mortar.
The role of redispersible latex powder:
The redispersible latex powder forms a film after being dispersed and acts as a second adhesive to play a strengthening role;
The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or “secondary dispersion”);
The film-forming polymer resin is distributed in the entire mortar system as a reinforcing material, thereby increasing the cohesion of the mortar;
