How to Identify and Choose Redispersible Polymer Powder?

Understand the Project Requirements of Redispersible Polymer Powder:

Before buying an RDP, it’s important to understand the project requirements and specifications. The quality of RDP varies depending on the grade, so the requirements of your project will determine which grade of RDP to choose. For instance, if you need to improve your mortar’s water resistance, you should choose an RDP with a high hydrophobic property.

Check the Polymer Composition of Redispersible Polymer Powder:

The polymer composition of RDP is a crucial factor in determining its quality and grade. The polymers used for different RDP grades vary in their properties. Some of the common polymers used for making RDP include ethylene-vinyl acetate copolymer, styrene-butadiene copolymer, and others. Check the polymer composition before selecting an RDP.

Look for High Solid Content of Redispersible Polymer Powder:

The solid content of RDP refers to the percentage of polymer powder contained in the mixture. It’s important to choose an RDP with a high solid content because it directly impacts the strength and bonding properties of mortar. The higher the solid content of RDP, the stronger the bonding capacity of mortar.

Consider Adhesion and Cohesion of Redispersible Polymer Powder:

Adhesion and cohesion are important properties of RDP that affect the performance of the final product. Adhesion refers to the bonding strength between two different surfaces, while cohesion is the bonding strength between particles on the same surface. A high adhesion and cohesion property of RDP is desirable, as it improves the strength and durability of mortar.

Check the Manufacturer's Reputation of Redispersible Polymer Powder:

Finally, it’s essential to choose an RDP from a reliable and reputable manufacturer. RDP quality and consistency vary from manufacturer to manufacturer. So, research and read reviews of the manufacturer before investing in their product. A manufacturer with a positive reputation and years of experience can provide you with a high-quality RDP that meets your project requirements.


Redispersible polymer powder is an essential material that can significantly improve the properties of mortar and dry mix. Choosing the right type of redispersible polymer powder is important for the success of your project. When selecting a Redispersible Polymer Powder, consider the project requirements, polymer composition, solid content, adhesion, cohesion, and the manufacturer’s reputation. It is important to keep these factors in mind when choosing Redispersible Polymer Powder for your project, so you can ensure a high-quality product and a long-lasting result.
