Functions And Applications of redispersible-latex-powder ( RDP)
Characteristics of redispersible latex powder:
1. The redispersible latex powder product is a water-soluble redispersible powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid.
2. VAE redispersible emulsion powder has film-forming property. 50% aqueous solution forms lotion shape and forms plastic film after being put on glass for 24 hours.
3. The formed film has a certain degree of flexibility and water resistance. Can meet national standards.
4. Redistributable latex powder has high performance: it has high bonding ability, unique performance, and outstanding waterproof performance. It has good bonding strength and endows mortar with excellent alkali resistance, which can improve the adhesion, flexural strength, plasticity, wear resistance, and workability of mortar. In addition, it also has strong flexibility in crack resistant mortar.
Introduction to the application of redispersible latex powder in dry powder mortar:
◆ Masonry mortar and plastering mortar: redispersible latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve quality problems such as cracking and penetration between traditional masonry mortar.
◆ Self leveling mortar and flooring materials: redispersible latex powder has high strength, good cohesion, adhesion, and required flexibility. Can improve the adhesion, wear resistance, and water retention of the materials used. It can ping excellent rheological properties, workability, and self smoothing performance to ground self leveling mortar and leveling mortar.
◆ Ceramic tile adhesive and tile pointing agent: redispersible latex powder has good adhesion, good water retention, long opening time, flexibility, anti sagging performance, and good resistance to freeze-thaw cycles. It can provide high adhesion, anti slip, and good construction operability for tile adhesive, thin layer tile adhesive, and sealant.
◆ Waterproof mortar: redispersible latex powder enhances the bonding strength of all substrates, reduces elastic modulus, increases water retention, and reduces water penetration. It provides a long-lasting sealing system with hydrophobic and waterproof requirements for products with high flexibility, weather resistance, and high waterproofing requirements.
◆ External wall insulation mortar: The redispersible latex powder is used in the external wall insulation system to enhance the cohesion of the mortar and the bonding force to the insulation board, providing you with insulation while reducing energy consumption. To achieve the necessary workability, flexural strength, and flexibility in external wall insulation mortar products, your mortar products can have good bonding performance with a series of insulation materials and substrates. At the same time, it also helps to improve the impact resistance and surface crack resistance.
◆ Repair mortar: The redispersible latex powder has the required flexibility, shrinkage, high adhesion, and suitable bending and tensile strength. Ensure that the repair mortar meets the above requirements and is used for repairing both structural and non structural concrete.
◆ Interface mortar: Redispersible latex powder is mainly used to treat the surfaces of concrete, aerated concrete, gray sand picks, and fly ash picks, solving problems such as difficult bonding, hollowing, cracking, and peeling of the plaster layer caused by excessive water absorption or smoothness of these surfaces. Enhanced adhesion, less prone to detachment, and water resistance, with excellent freeze-thaw resistance. It has a significant effect on simple operation and convenient construction.
Redispersible latex powder is mainly used for:
Internal and external wall putty powder
