The redispersible emulsion powder is a water-soluble redispersible powder, which is a copolymer of ethylene and vinyl acetate, and polyvinyl alcohol is used as a protective colloid. By adding redispersible emulsion powder, the performance of cement or gypsum-based mortar can meet the needs of various construction buildings. Redispersible emulsion powders have a wide range of applications due to their high binding capacity and unique properties, such as water resistance, workability and heat insulation.

Performance and function of redispersible latex powder

The redispersible emulsion powder product is a water-soluble redispersible powder, which is a copolymer of ethylene and vinyl acetate, and polyvinyl alcohol is used as a protective colloid. Due to the high binding capacity and unique properties of redispersible latex powders, such as water resistance, workability and heat insulation, their application range is extremely wide. Re-dispersible latex powder is mainly used in: interior and exterior wall putty powder, tile adhesive, tile jointing agent, dry powder interface agent, exterior insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar and other dry-mixed mortar. Redispersible latex powder is a green environmental protection, building energy saving, high quality multi-purpose powder building materials, is an essential and important functional additives for dry-mixed mortar. It can improve the performance of mortar, improve the strength of mortar, improve the bonding strength of mortar and various substrates, improve the flexibility and variability of mortar, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention capacity, constructability. In addition, the hydrophobic latex powder can make the mortar has good water resistance.

Function and Application of Redispersible Emulsion Powder

Redispersible emulsion powder is a kind of powder binder made by spray drying of special emulsion (high molecular polymer). This powder can be quickly re-dispersed after contact with water to form an emulsion, and has the same properties as the initial emulsion, that is, after evaporation of water can form a film, this film has high flexibility, high weather resistance and high adhesion to various substrates.
