By spray-dying polymer emulsions, redispersible polymer powder (RDP) is created. The polymer emulsion is emulsified and distributed after being mixed with water in the mortar, and it becomes more stable. When the RDP is emulsified and distributed in water, it forms a polymer coating that improves the mortar’s varied properties after the water evaporates. RDP has a distinct effect on the properties of dry mortars. Get this from a redispersible polymer powder manufacturer.
Redispersible Polymer Powder’s Functions:
Increase mortar’s impact resistance, durability, and abrasion resistance:
The polymer powder particles can fill the mortar cavity, increasing the density of the mortar and improving its wear resistance. To avoid being destroyed, the mortar will be relaxed by an external force. The polymer film can last indefinitely in the mortar system.
Improve the workability and building of mortar:
The polymer powder particles in the mortar have a lubricating effect. This allows the mortar components to flow separately. The polymer powder has an inducing effect on air, allowing the mortar to be compressed for improved construction and workability.
Improve mortar’s bonding strength and cohesiveness:
After producing a polymer film in the mortar, the RDP has strong tensile strength and bonding strength on various substrates. This plays a vital role in the adhesion ability of mortar and organic materials or smooth surface substrates. To improve mortar cohesion, the film-forming polymer powder is disseminated throughout the entire mortar system as a reinforcing material.
Improve weather and freeze-thaw resistance, and the mortar’s resistance to cracking:
RDP is a flexible thermoplastic resin that allows the mortar to respond to changes in external cold and hot environments. It prevents the mortar from cracking due to temperature fluctuations.
Improve the mortar’s hydrophobicity to prevent water absorption:
The RDP can build coatings on the mortar cavity and surface that will not disperse in water, preventing water infiltration and improving the mortar’s impermeability. With specific hydrophobic RDP, the mortar will be more hydrophobic.
Applications In Industry:
Composite External Thermal Insulation Systems (ETICS):
To strengthen the bond strength, use bonding mortar to ensure that the wall and the EPS board are linked to one other.
The grouts can improve the mortar’s impermeability and prevent water from getting in. The grouts also offer excellent adhesion to the tile’s edge, and low shrinkage and flexibility. Renovation of tiles and wood plastered grouts:
Floor mortars that self-level:
Determine the mortar’s elastic modulus matching ability, bending resistance, and fracture resistance. Improve the mortar’s wear resistance, bonding strength, and cohesiveness.
Putty for interior and external walls:
Improve the putty’s bonding strength while also ensuring that it has enough flexibility to absorb the various strain stresses induced by different substrates. Make sure the putty has strong aging resistance, impermeability, and moisture resistance.
Adhesive for tiles:
Tile adhesives enable high-strength bonding while also allowing the mortar to adjust to a varying substrate and tile thermal expansion coefficients. Increase the efficiency of a building and make it easier to build.
