Analysis of the properties and functions of redispersed latex powder

Resentrble latex powder product is water soluble redisperse powder, ethylene, vinyl acetate copolymer, with polyvinyl alcohol To protect the colloid. The reusable latex powder has a high bonding ability and unique properties. Such as: water resistance, construction, and heat insulation Therefore, the scope of their application is extremely extensive. Redispersed latex powder is mainly use in. Internal and external wall putty powder, ceramic tile binder, ceramic tile bonding agent. Dry powder interface agent, external wall external insulation mortar. Self-leveling mortar, repair mortar, decorative mortar, waterproof mortar and other dry mixed mortar.

Redispersed latex powder is a green environmental protection. Building energy saving, high quality and multi-purpose powder building material. And is an essential and important functional additive of dry mixed mortar. It can improve the performance of mortar. Improve the strength of mortar, improve the bonding strength of mortar and various substrate. Improve the flexibility and variable action of mortar, compressive strength, folding strength, wear resistance, toughness, adhesive relay and water retention ability, construction ability. In addition, with a hydrophobic latex powder can make the mortar have a very good waterproof.

The effect of redispersed latex powder:
  • 1.The latex powder can be redisperse to form a film and play an enhancing role as the second adhesive; RDP&VAE
  • 2. Protect the colloid to be absorbe by the mortar system (it will not be destroye by water after film, or “secondary dispersion”; RDP&VAE
  • 3. The film-forming polymer resin is distribute as a reinforcing material and the whole mortar system, thus increasing the cohesion of mortar; it can be divided again Scattered latex powder is a kind of powder adhesive agent made of special emulsion (polymer) spray after drying. This powder can be quickly dispersed to form an emulsion after contact with water, and has the same properties as the initial emulsion, namely, the water evaporation can form a membrane, this membrane with high flexibility, high hou tolerance and high adhesion to various substrates.
