Product Overview
Redispersible emulsion powder is a new type of polymer powder. It usually appears as a white powder, with good dispersion and stability.
Product Characteristics
Good bonding performance: Can significantly improve the bonding strength of mortar and other materials with the base.
Flexibility: Give the material good flexibility, effectively prevent cracking.
Water resistance: Enhance the water resistance of the material, so that it remains stable in wet environments.
Improve construction performance: Make the mortar and so on have good workability and operability.
Product Use
Architectural Field
- External wall insulation system: enhance the adhesion of polystyrene board and base, improve the stability and durability of the system.
- Ceramic tile binder: improve the bonding strength between ceramic tile and base layer to prevent ceramic tile from falling off.
- Self-leveling floor material: improve the flow and strength of self-leveling.
Dry Mix Mortar
Such as plastering mortar, masonry mortar, etc., to improve its comprehensive performance.
Production Process
The polymer emulsion is prepared by emulsion polymerization, and then the emulsion is converted into powder by spray drying and other processes.
Market Prospects
With the continuous improvement of material performance requirements in the construction industry and the promotion of green building concepts, the market demand for redispersible emulsion powder continues to grow. It plays an important role in improving the quality of construction and extending the service life of buildings.
Use Precautions
