Audited Supplier Redispersible latex powder is made of ethylene/vinyl acetate copolymer emulsion after spray drying, with stable quality and high cost performance. It is a free-flowing polymer white powder.
In building dry powder, it is extremely necessary to add redispersible latex powder:
Redispersible latex powder can improve the bonding strength and cohesion of the material. This is because the polymer particles penetrate the pores and capillaries of the cement matrix and form a good cohesive strength after hydration with the cement.
Because the polymer resin itself has excellent adhesion, it plays an obvious role in improving the adhesion of cement mortar products to the substrate, especially the inorganic binder of cement is used to bond wood, fiber, PVC, EPS and other organic substrates. The improvement of poor sex is more obvious.
The redispersible latex powder mainly exerts the strength in the later stage and maintains the firmness of the building.

Many advantages of using redispersible latex powder (RDP):
After dispersion, it will form a film and play a reinforcing role as a second adhesive;
The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or "secondary dispersion");
The film-forming polymer resin is distributed in the entire mortar system as a reinforcing material, thereby increasing the cohesion of the mortar;
Improve construction performance in wet mortar; improve flow performance;
Increase thixotropy and sag resistance; improve cohesion;
Extend the open time; enhance water retention.
After the mortar is cured, the tensile strength is improved;
Increase bending strength;
Reduce the modulus of elasticity;
Improve deformability;
Increase material density;
Increase wear resistance
; Improve cohesive strength;
Reduce the depth of carbonization;
Reduce material water absorption;
Make the material have excellent water increase.
Advantages of RDP:
1. Simple, fast and convenient to use.
2. A small amount of addition can achieve the desired effect.
3. Save time and cost, shorten the project completion time.
Key properties:
- Supply high flexibility
- Increase adhesion strength
- Improves workability
- Improve water proofing of mortar
- Reduce water absorption
- Excellent rheology
- Increased impact and abrasion resistance
- Higher durability and freeze thaw resistance
- Improved wetting of the substrate
RDP storage:
Store non-dangerous goods in a dry environment below 30°C. Accident prevention rules related to dust protection must be followed.
Transport:
Standard packaging, 20 kg pp bags, including PE bags. Transported as non-hazardous chemicals.
RDP packaging and storage:
It should be stored in a cool and dry place. The recommended period of use is six months. Please use it as early as possible when using it in summer.
Keeping in a hot and humid place will increase the chance of agglomeration. After opening the bag, please use it once as much as possible, otherwise the bag must be sealed to avoid absorbing moisture from the air.
