Building Additive Redispersible Polymer Powder Cas No: 24937-78-8

Shengda redispersible latex powder has a very prominent bond strength, thereby improving the flexibility of the mortar and can have a longer opening time, it can be emulsified in the water after the water heat, the formation of polymer film in the mortar, improve the performance of mortar.
1.Improve the mortar impact resistance, durability, wear resistance: powder particles filled with mortar pore, mortar density increased, improved wear resistance. Under the action of external forces will produce slack without being damaged. Polymer film can be permanently present in the mortar system.
2.Improve the construction and ease of mortar: there is a lubricating effect between the polymer powder particles, so that the mortar component can flow alone, while the powder on the air induction effect, giving the second slurry compressibility, good construction and ease of mortar.
3.Improve the mortar bonding strength and cohesion: as an organic binder can be re-dispersible polymer powder after film formation, can form a high tensile strength and adhesive strength on different substrates. In the mortar and organic materials( EPS, extruded plastic foam board)and smooth surface adhesion of the substrate on the play a very important role. Film-forming polymer powder as a reinforcing material distributed throughout the mortar system, increasing the cohesion of the mortar.
4.Improve the weathering resistance of mortar, freeze-thaw resistance, prevent mortar cracking: redispersible latex powder belongs to the thermoplastic resin, has good flexibility, can make the mortar to cope with changes in the external hot and cold environment, effectively prevent the mortar due to changes in temperature and cracking.
5.Improve the water repellency of mortar, reduce water absorption: redispersible polymer powder in the mortar cavity and the surface of the film, the polymer film will not be two times after the water dispersion, prevent the invasion of water, improve the impermeability.Special re-dispersible polymer powder with hydrophobic effect, the hydrophobic effect is better.
6.Improve the mortar flexural strength and flexural strength: dispersible polymer powder its use, can be very good to improve the performance of the mortar, and different Sublevel latex powder for dry mortar somewhat different role.
