Audited Supplier RDP is based on an aqueous polymer dispersion and does not contain any solvents. In this process, the water-emulsified monomer (with the initiator) reacts to start emulsion polymerization, through which the monomers are connected to form a long-chain molecule, a polymer. In this polymer emulsion, the stabilizer on the surface of the particles must prevent the latex from coalescing under any circumstances and thus causing an unstable state. Then by adding different additives to prepare a mixture for spray drying, and then add protective colloid and anti-caking agent to make the polymer form a free flowing powder that can be redispersed in water after spray drying.
RDP can form a film as a second adhesive after dispersion to enhance its role; protect the colloid from being absorbed by the mortar system; the film-forming polymer resin acts as a reinforcing material and is distributed throughout the mortar system, thereby increasing the cohesion of the mortar.
RDP is a building green, energy-saving, environmentally friendly, high-quality multi-purpose powder building material, and is an important and important functional additive for dry-mixed mortar. In addition, RDP is also water-repellent, which can make the mortar very waterproof.

The redispersible latex powder is usually in the form of white powder. Its component is polymer resin, which is located in the core part of the rubber powder particles, and is also the main component of the redispersible latex powder. A layer of hydrophilic material wrapped on the surface of the redispersible latex powder particles, most of the maintenance colloid of the redispersible latex powder is polyvinyl alcohol.
It can be applied in the following building materials
1. Application in repairing mortar
Ensure the adhesion of the mortar and increase the durability of the repaired surface. Reducing the elastic modulus makes it highly resistant to strain.
2. Application in waterproof mortar
Improve workability; increase water retention; improve cement hydration; reduce mortar modulus of elasticity and enhance matching to the base. Improve mortar density, increase flexibility, resist cracking or have bridging ability.
3. Application in caulk
Let the impermeability of mortar prevent water intrusion. At the same time, it has good adhesion to the tile edge, low shrinkage and flexibility.
4. Application in ceramic tile adhesive
Provide high-strength bonding for the mortar and give the mortar enough flexibility to strain the different thermal expansion coefficients of the substrate and the ceramic tile.
