Redispersible polymer powder is an important chemical additive in modern dry-mix mortar formulations. It is widely used in tile adhesives, EIFS, self-leveling mortars, repair mortars, waterproof mortars, and wall putty to improve bonding strength, flexibility, and overall application performance.
At Botai Chemical, we supply high-quality rdp powder for construction applications and help customers choose suitable grades for different mortar systems.
What Is Redispersible Polymer Powder?
Redispersible polymer powder is made by spray-drying polymer emulsion into powder form. When mixed with water, it can redisperse again and recover the main properties of the original emulsion. This is why redispersible powder is widely used in dry-mix mortar production.
After drying, the polymer forms a flexible film inside the mortar, helping bind cement, sand, and fillers together more effectively.
Why Use RDP Powder?
The core function of rdp powder is to act as an adhesion agent. It improves bonding strength and helps mortar perform better on different substrates. At the same time, redispersible emulsion powder can also improve flexibility, crack resistance, water resistance, and workability.
Main benefits include:
- Improve bonding strength
- Enhance flexibility
- Reduce cracking risk
- Improve water resistance
- Increase durability
- Improve workability and open time
Main Applications
Botai Chemical redispersible polymer powder is commonly used in:
