Redispersible Polymer Powder - Cellulose Ether

Redispersible Polymer powder(ordinary type) is composed of a special polymers made of powder adhesive after spray drying. this powder is contact with water can be dispersed again in soon after forming emulsion, and with the nature of the same as the initial emulsion, namely the film can be formed after the moisture evaporation, the film has high flexibility, high resistance to weathering and on various substrate with high caking property. the powder environmental protection, energy saving, high quality, used for powder materials, dry-mix mortar is an indispensable functional additives. It can improve the performance of mortar, raise the strength of the mortar, improve the bonding strength of mortar with different base material, improve the mortar flexible and variable line, compressive strength, flexural strength, abrasion resistance and toughness, stick relay and water retention, constructability.

Feature: Redispersible Polymer powder(Redispersible Latex powder) is the main raw material in production of internal, external wall putty, adhesive mortar and plaster mortar. the powder is specially applied as the agglutinant of basis materials on triple superphosphate, Talcum powder and white cement and so on. It can improve the adhesion properties water resistance, flexural strength and operability of the basis materials.

Usage: The quantity of the powder is to different kinds of basis material. the substrate mixture should be stirred and dispersed fully to ensure the excellent stability of the products. However, high temperature generated from high-pressure and shear stress when mixed should be avoided.

Attentions: Stored in cool and dry place. Please use within the guarantee period. To avoid metamorphism caused by absorbing ambient moisture, as possible one-time use after the bag is opened.

Product elucidation

Redispersible Polymer powder is mainly applied for the dry mixed mortar of the construction industry, and is the important additive of dry mixed mortar.

Redispersible Polymer powder has obvious functions in the dry mixed mortar. It can improve strength and bonding force, the elastic bending strength and rupture strength of materials. It also improve the freezeproof property, weathering resistance, durability and wear resistance of the materials. As well as intensify the hydrophobicity and reduce the water absorption, improve the construction characteristic and reduce the contraction ratio of materials. The powder can effciently prevent cracking.

1,Improvement of the bonding strength and bonding force.

It is quite necessary to add Redispersible Polymer powder to the products of dry mortar. It can obviously improve the bonding strength and bonding force of materials, as it is because the matrix hole and capillary penetration of the polymer particle to cements form into fine bonding strength after hydrating of the cements. Furthermore, due to the fine boding force of polymer resin, the powder has better effects on improve of the boding force of dry mortar to the basis materials, especially improving the bad bonding properties of the inorganic bonder such as cement to the organic materials likes woods, fiber, PVC and EPS.

2,Improvement of the counter bending and tensile property

In the rigid structures after hydrating of the cement mortar, the film elasticity and tenacity of the polymer has the similar function of the mobile joint between the cement mortar particles, the it can bear high distortion load and reduce the stress, as well as improve the tension and resistance to bending.

3,Improvement of the impact resistance

Redispersible Polymer powder is the thermoplastic resin. The soft covered on the surface of mortar particles can absorb outside force impact that is tensile without damage, so as to improve the impact resistance of mortar.

4,Improvement of the hydrophobicity and reduction of the water absorption

Addition of the Redispersible Polymer powder can improve the microscopic structure of the cement mortar. The polymer forms into the irreversible network during the cement hydrating process. Capillary in the close cement gelation can hold up the water absorption and water penetration. so as to improve the penetration resistance capability.

5,Improvement of the wear resistance and durability

Addition of the Redispersible Polymer powder can intensify the dense grade between the cement mortar particles and polymer film. Strengthening of the boding force correspondingly improves the shearing stress-bearing capacity of the mortar, reduces the wear rate, improve the wear resistance, and prolongs the service life of the mortar.

6,Improvement of the freeze thawing stability and efficient prevention of the cracking of materials

The plasticity function possessed by the thermoplastic resin of Redispersible Polymer powder can overcome the flatulence damage for cement mortar materials brought by temperature difference changes. It can overcome the defects of dry shrinkage and distortion of single cement mortar that is easy to be cracked, and make the material flexible, so as to improve the long stability of materials.

Typical Applications of Redispersible Polymer Powders

Redispersible polymer powders (RDPs) have become an important part of modern building materials. Its unique properties make it an ideal ingredient for a wide range of applications. From improved processability of building materials to high adhesive properties, RDP has revolutionized the field of construction.

Here are some typical applications of RDP:

1. Exterior Insulation and Finishing System (EIFS)

EIFS is a popular method of covering exterior walls with weather resistant insulation. One of the main components of EIFS is RDP. It contributes to the strength, adhesion and flexibility of EIFS, ensuring it can withstand varying weather conditions.

2. Tile Adhesive

Tile adhesives are widely used in interior and exterior tile applications. RDP is used to enhance the performance of these adhesives by increasing bond strength, flexibility and water resistance. This ensures that the tiles will stay in place even under heavy loads or changing weather conditions.

3. Self-leveling floor compound

Self-leveling floor compound is used to create a smooth, level surface on concrete floors. Adding RDP to these compounds improves the adhesion, processability and flow of the mixture. This ensures a flat, level and durable floor.

4. Mortar and plaster

Mortar and plaster are used to bond brick, stone and concrete blocks together and to create a smooth finish on walls. RDP is an important part of these blends as it improves their water resistance, adhesive properties and flexibility. This means mortars and plasters can withstand different weather conditions and remain strong over time.

5. Gypsum board joint compound

Drywall joint compound is used to fill gaps and joints between drywall. Adding RDP to these compounds improves processability, adhesion and durability. This ensures that the joint compound remains strong, crack resistant and easy to apply.

6. Waterproof membrane

Waterproofing membranes are used to prevent water from penetrating buildings. RDP has been added to these membranes to enhance their flexibility and adhesion, ensuring they can withstand varying weather conditions and remain strong over time.

7. Plastering

Plastering is the process of applying a layer of plaster to walls and ceilings. RDP is used to improve the adhesion and workability of the stucco, ensuring that it will apply smoothly and evenly.

8. Textured coating

Textured paints are used to create decorative effects on exterior walls. RDP is used to increase the bond strength and durability of these coatings, ensuring they can withstand varying weather conditions and remain attractive over time.

RDP has become an indispensable part of modern building materials due to its unique properties. Its use has revolutionized the field of construction, making it possible to manufacture high-quality materials with enhanced performance characteristics. Whether it is EIFS, tile adhesives, self-leveling floor compounds, mortars and plasters, plasterboard joint compounds, waterproofing membranes, plasters or texture coatings, RDP has proven to be a versatile and reliable ingredient.
