What is the Composition of Redispersible Latex Powder?

Redispersible latex powder is usually white powder, but a few have other colors.

Its ingredients include:

Polymer resin: Located in the core part of the rubber powder particles, it is also the main component of the redispersible latex powder.

Additives (internal): together with the resin, it plays a role in modifying the resin.

Additives (external): In order to further expand the performance of redispersible latex powder, another material is added.

Protective colloid: A layer of hydrophilic material wrapped on the surface of redispersible latex powder particles. Most of the protective colloids of redispersible latex powder are polyvinyl alcohol.

VAE Powder

Anti-caking agent: fine mineral filler, mainly used to prevent rubber powder from agglomerating during storage and transportation and to facilitate the flow of rubber powder (pour out from paper bags or tankers)

effect

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;

Action in wet mortar

Improve construction performance; improve flow performance; increase thixotropy and sag resistance; improve cohesion; extend open time; enhance water retention.

After curing

Increase tensile strength; increase bending strength; reduce elastic modulus; improve deformability; increase material compactness; increase wear resistance; increase cohesive strength; reduce carbonization depth; reduce material water absorption; make materials have extreme Good water-increasing (adding water-increasing rubber powder).
