RDP emulsion

The redispersible emulsion powder is first physically mixed with other inorganic cementing materials (such as cement, hydrated lime, etc.) and various aggregates and additives to make dry mixed mortar. When the dry mixed mortar is mixed with water, under the action of hydrophilic protective colloid (polyvinyl alcohol) and mechanical shear force, the rubber powder particles are dispersed into the water, and affect the rheology, constructability, compressive bending strength and tensile bond strength of the mortar.   Ceramic tile binder is the cement-based bonding material of ceramic tile, which can be used to paste natural stone such as ceramic tile, polished brick and granite. The addition of redispersible emulsion powder can extend the working time and adjust the time of the newly mixed mortar, improve the water retention performance and anti-hanging performance; Improve the bonding property, deformation resistance and aging resistance of hardened mortar.   External wall insulation system has been applied in the field of the world, and its installation on the external wall of the building mainly saves the energy consumption of the building 40%-70%. Dry mix mortar modified with redispersing emulsion powder is used to bond polystyrene board to the wall while protecting the polystyrene board. For protective mortars as well as cement-based decorative mortars, polymer adhesive powder provides good adhesion, impact resistance, low water absorption and high flexibility even in harsh environments.   After film formation, the emulsion and redispersed emulsion powder can form high tensile strength and bond strength on different materials, and they are combined with cement as the second binder in the mortar, and the cement and polymer play the corresponding special features respectively, so that the performance of the mortar can be improved.   Even if the type of emulsion powder copolymer is the same, due to the different production processes of different manufacturers, the properties of latex powder are different, and its properties in the corresponding mortar should be considered comprehensively when selecting rubber powder. With the increase of the national promotion of the use of dry mixed mortar, the demand for redispersible emulsion powder is showing a rapid growth momentum, which is bound to usher in a new peak of use.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

Redispersible emulsion powder is a modified emulsion powder obtained by spray drying of a binary or ternary copolymer of vinyl acetate and tertiary vinyl carbonate -VeoVa or ethylene or acrylic ester, which has good redispersibility and is re-dispersed into emulsion when it is in contact with water, and its chemical properties are exactly the same as the initial emulsion. After mixing with the water in the mortar, it emulsifies and disperses in the water to form a stable polymerization emulsion. After dispersing in water, the water evaporates, forming a polymer film in the mortar after drying, improving the performance of the mortar. Different dispersible latex powders have different effects on the dry mortar. 1. Improve the impact resistance, durability and wear resistance of mortar The rubber powder particles fill the cavity of the mortar, the densification of the mortar is increased, and the wear resistance is improved. Under the action of external forces will produce relaxation and not be destroyed. The polymer film can exist in the mortar system for a long time.   2. Improve the bonding strength and cohesion of mortar As an organic binder, dispersible emulsion powders provide high tensile strength and bonding strength on different substrates. It plays a very important role in the adhesion between mortar and organic materials (molded plates, extruded plates) and smooth surface substrates. The film-forming polymer rubber powder is distributed in the whole mortar system as a reinforcing material to increase the cohesion of the mortar.   3. Improve the mortar's weatherability, freeze-thaw resistance and prevent mortar crackingThe RDP emulsion powder is a thermoplastic resin adhesive powder with good flexibility, which can make the mortar cope with the external cold and hot environment changes and effectively prevent the mortar from cracking due to the change in temperature difference.   4. Improve the hydrophobicity of mortar and reduce water absorptionThe RDP emulsion powder forms a film in the mortar cavity and surface, and the polymer resin film will not disperse twice after encountering water, preventing the invasion of water and improving the impermeability. Enhanced dispersible adhesive powder with hydrophobic effect has better hydrophobic effect.   5. Improve the bending strength and flexural strength of mortar The polymer film formed by dispersible emulsion powder has good flexibility. The film is formed in the gap and surface of cement mortar particles to form a flexible connection, so that the brittle cement mortar becomes elastic. The mortar added with dispersible emulsion powder has much better tensile and flexural properties than ordinary mortar.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com   ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

RDP emulsion refers to a Redispersible Polymer Powder (RDP) emulsion. RDP is a polymer powder that can be easily dispersed in water to form a stable emulsion. It is typically composed of polymer resins, plasticizers, and other additives.   RDP emulsions are commonly used in various industries, including construction, coatings, and adhesives. Some of their main uses include:    1. Construction Applications: RDP emulsions are widely used in construction applications, such as tile adhesives, grouts, self-leveling compounds, and cement/render mortars. They enhance the workability, adhesive strength, and flexibility of these materials, improving their performance and durability.   2. Coatings and Paints: RDP emulsions are utilized in water-based coatings and paints. They contribute to improved film formation, bonding strength, and water resistance. RDP emulsions are commonly used in exterior paints, interior wall coatings, and decorative finishes.   3. Textile Applications: RDP emulsions can be used as binders in textile printing and finishing processes. They help improve the adhesion of dyes and pigments to textiles, enhance color fastness, and provide fabric stiffness and durability.    4. Adhesives: RDP emulsions are employed in various adhesive formulations, such as wood adhesives, paper bonding adhesives, and laminating adhesives. They improve the adhesive strength, tackiness, and bonding performance of the adhesives.   5. Other Applications: RDP emulsions find use in other areas, including paper coatings, leather treatments, and ceramic applications.   Overall, RDP emulsions play a crucial role in enhancing the performance and properties of various products, providing improved adhesion, flexibility, water resistance, and durability.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
