Redispersible emulsion powder is the dispersion of polymer lotion after spray drying. With its promotion and application, the performance of traditional building materials has been greatly improved, and the bonding strength and cohesion of the materials have been improved. It can improve the performance of mortar, increase its strength, enhance the bonding strength between mortar and various substrates, enhance the flexibility and deformability, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention capacity, and constructability of mortar. In addition, latex powder with hydrophobicity can make the mortar have good waterproof properties. Redispersible latex powder is mainly used in various dry mixed mortars such as putty powder for internal and external walls, ceramic tile bonding agent, ceramic tile pointing agent, dry powder interface agent, external wall insulation mortar, self leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc.
Redispersible latex powder is a green, environmentally friendly, energy-saving, high-quality multi-purpose powder building material, and an important functional additive for dry mixed mortar. It can improve the performance of mortar, increase its strength, enhance the bonding strength between mortar and various substrates, enhance the flexibility and variability, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention capacity, and constructability of mortar. In addition, latex powder with hydrophobicity can make the mortar have good waterproof properties.
The redispersible latex powder product is a water-soluble redispersible powder, a copolymer of ethylene and vinyl acetate, with polyvinyl alcohol PVA as its protective colloid.
In recent years, the demand for redispersible latex powder in Europe and North America has grown slowly due to market saturation. On the contrary, with the gradual implementation of China’s building energy conservation policy and the vigorous promotion of dry mixed mortar for buildings, the use of redispersible latex powder in Chinese Mainland has grown rapidly. Foreign multinational companies and some domestic enterprises have also launched projects of redispersible latex powder across the country.
Main applications:
Redispersible latex powder is a water-soluble redispersible powder that is commonly used as a polymer modified ready-mixed mortar based on mineral cementitious materials, such as additives for cementitious, lime based, and gypsum based materials. Under hydration, it has the following 5 advantages:
1. Enhance the adhesion and mechanical properties between mortar and ordinary supports;
2. Has extremely outstanding waterproof performance;
3. Improve the workability of putty and adhesive construction.
