Redispersible polymer powder

Aosen New Material is a professional and reliable supplier of Redispersible Polymer Powder. Redispersible Polymer Powder stands as the preeminent binder within cement - based and gypsum - based dry powder materials. Redispersible Polymer Powder is a powder obtained by spray - drying polymer emulsion. Once Redispersible Polymer Powder is re - emulsified with water, Redispersible Polymer Powder exhibits the identical properties to the original emulsion. Specifically, after water evaporation, a film can be formed. This film is characterized by high toughness, excellent weather resistance, and strong adhesion to a substrate. Moreover, the latex powder featuring hydrophobic properties is capable of enhancing the waterproof performance of the waterproof mortar. Aosen provide customers Redispersible Polymer Powder with good quality and reasonable price , feel free to contact us for sample!

Product Description

Product name: Redispersible Polymer Powder

Cas No.: 24937-78-8

Appearance: White or light yellow powder

Redispersible latex powder exhibits excellent performance, capable of enhancing construction properties, improving the fluidity and workability of mortar, extending open time, and enhancing water retention, making construction more convenient; in terms of mechanical properties, bonding and flexural strength are significantly increased, while the elastic modulus is reduced; durability is outstanding, with significant improvements in water resistance, alkali resistance, and wear resistance. Due to these characteristics, redispersible latex powder is widely used in the construction field, such as in tile adhesives, bonding and rendering mortars for external wall thermal insulation systems, tile grouting agents, and concrete interface mortars.

The features of Redispersible polymer powders

(1) Construction Performance: Redispersible polymer powders can optimize the flow properties of wet mortar, making application and spreading smoother and reducing construction resistance. Additionally, they enhance thixotropy and sag resistance, preventing the mortar from flowing during vertical or inclined surface construction, ensuring flatness and uniformity.

(2) Mechanical Performance: Redispersible polymer powders have outstanding bonding strength, which can tightly bind mortar to the substrate, enhancing tensile and cohesive strength, and preventing material from falling off. Redispersible polymer powders can also improve flexural properties, making the mortar more resilient when subjected to bending forces. Compared to ordinary mortar, the tensile flexural strength can be increased by several times after adding polymer powders.

(3) Durability Performance: Redispersible polymer powders can enhance water resistance and increase alkali resistance, protecting materials from alkali erosion. They also improve wear resistance, with the polymer powder particles filling pores, increasing compactness, enhancing surface wear resistance, and extending the service life.

Packaging And Transportation Of Redispersible polymer powders

Considering the characteristics of the Redispersible polymer powders , Redispersible polymer powders should be loaded and discharge lightly during transportation to prevent collision, rain, sun exposure, and pollution. Products should be stored in a ventilated, dry, and clean warehouse, and stacking is strictly prohibited.

The Packaging of Redispersible polymer powders is 25kg/bag
