Redispersible powder, the Chinese name is redispersible polymer powder, while the English name directly corresponds to its descriptive characteristics. It is a kind of polymer lotion powder after spray drying treatment, and has the ability to re disperse in aqueous solution to form lotion .As a high-performance powder adhesive, redispersible latex powder (RDP) has demonstrated its unique advantages and characteristics in multiple fields.
Redispersible latex powder has significant environmental characteristics, and its production process does not contain organic solvents or volatile organic compounds with extremely low content, which meets the requirements of modern green buildings and environmentally friendly construction. This characteristic ensures that it does not pose a threat to the environment and human health during its application, making it an important representative of green building materials.
RDP can be quickly and evenly dispersed in water to form a stable lotion. This is because of its unique surfactant formula, which can significantly reduce the surface tension between solid particles, so that latex powder particles can easily disperse and re form lotion. This excellent dispersion and redispersion performance ensures its stability and reliability under various construction conditions.
After contact with water, redispersible latex powder can quickly redisperse and form a film layer with strong adhesive strength. This film layer not only has high flexibility and weather resistance, but also exhibits excellent adhesion to various substrates. Therefore, RDP plays an important role in improving the performance of building materials such as mortar and coatings, significantly enhancing their bonding strength, compressive strength, flexural strength, and wear resistance.
RDP is widely used in multiple fields due to its unique performance. In the construction industry, it is mainly used in dry mixed mortar such as putty powder for interior and exterior walls, tile adhesive, waterproof mortar, etc., significantly improving construction quality and material performance. At the same time, it is widely used in the fields of coatings, textile printing and dyeing, cleaning agents, etc., providing high-performance additives and auxiliaries for these industries.
The use of redispersible latex powder for construction operation is simple and fast. Construction personnel only need to add it to water and stir evenly before use, without the need for complex processes and equipment. In addition, due to the absence of harmful substances such as organic solvents, RDP does not produce harmful gases and dust pollution during the construction process, ensuring the safety and health of construction personnel.
