Redispersible Polymer Powder (RPP) is a white powder prepared from polymer emulsion through a spray drying process and is widely used in the field of building materials. Its main function is to improve the performance of building materials, such as improving bond strength, crack resistance, flexibility and water resistance.
1. Wall plastering and leveling materials
Redispersible latex powder is widely used in wall plastering and leveling materials. Adding a certain amount of latex powder to traditional cement mortar can significantly improve the flexibility and adhesion of the mortar, making the mortar better adhere to the substrate and less likely to cause hollowing and cracking. In addition, the addition of latex powder can also improve the construction performance of the mortar, making the mortar easier to apply and polish, thereby ensuring the flatness and smoothness of the wall.
2. Tile adhesive
In tile adhesives, the use of redispersible latex powder has become an industry standard. Compared with traditional cement-based tile adhesives, adhesives incorporating latex powder have higher bonding strength and anti-slip properties. Latex powder gives the adhesive better flexibility, allowing it to adapt to the different expansion coefficients of the substrate and ceramic tiles in changes in temperature and humidity, reducing the risk of cracking and falling off. In addition, latex powder also improves the water resistance and frost resistance of the binder, making it suitable for various complex indoor and outdoor environments.
3. Waterproof mortar
The application of redispersible latex powder in waterproof mortar is also very important. Latex powder interacts with cement and other additives to form a dense waterproof layer that can effectively prevent moisture penetration. This kind of waterproof mortar is widely used in building parts that require waterproofing treatment, such as basements, roofs, and swimming pools. Due to the addition of latex powder, the waterproof mortar not only has excellent waterproof properties, but also retains good breathability, thus avoiding moisture problems inside the building.
4. External wall insulation system
In External Thermal Insulation Composite Systems (ETICS), redispersible latex powder plays a key role. It is added to the interface mortar used for insulation panels to improve the bonding strength and flexibility of the mortar, thereby ensuring a strong bond between the insulation panels and the base wall and preventing cracking or falling off problems. In addition, latex powder also improves the freeze-thaw resistance and durability of the interface mortar, allowing the external insulation system to maintain good performance under various climate conditions.
5. Self-leveling mortar
Self-leveling mortar is a high-flow mortar applied to floors that automatically levels the floor and creates a smooth, even surface. The application of redispersible latex powder in self-leveling mortar significantly improves the fluidity and adhesion of the mortar, allowing it to flow quickly within a wide range and level itself. In addition, the addition of latex powder also enhances the compressive strength and anti-wear properties of self-leveling mortar, ensuring the durability of the floor.
6. Repair mortar
It is inevitable that some cracks or damage will occur during the use of buildings, and repair mortar is the material used to repair these defects. The introduction of redispersible latex powder gives the repair mortar better adhesion and flexibility, allowing it to better fill cracks and form a good combination with the original building materials. Latex powder also improves the crack resistance and durability of the repair mortar, allowing the repaired area to remain stable for a long time.
7. Fire retardant coating
In fire-retardant coatings, adding redispersible latex powder can improve the adhesion and flexibility of the coating, allowing the coating to form a stable protective layer in a fire, preventing further damage to buildings by flames and high temperatures. In addition, latex powder can also improve the water resistance and aging resistance of fire retardant coatings and extend their service life.
8. Construction glue
Redispersible latex powder is also one of the important raw materials for making construction glue. It gives the glue better adhesion and durability, allowing it to be used for bonding a variety of building materials, such as wood, gypsum board, stone, etc. The versatility of latex powder gives construction glue a wide range of application prospects, especially in the field of decoration and decoration.
As a functional additive, redispersible latex powder has a wide range of applications in the construction field. It not only significantly improves the physical properties of building materials, but also increases the convenience and efficiency of construction. With the continuous development of construction technology, the application prospects of redispersible latex powder will become broader and become an indispensable and important component of modern building materials.
