How to store RDP (VAE)Re-dispersible polymer powder?

Re-dispersible latex powder (RDP) is a convenient additive for a variety of construction applications, including wall putty, mortar, plastering and more. However, proper storage of RDP is essential to ensure its effectiveness and longevity. In this article, we will discuss the different storage methods for RDP powders and how to best maintain its properties.

RDP / VAE powders must be stored in a dry, cool space. Exposure to moisture and high temperatures will affect the quality of the powder, resulting in caking and reduced efficacy. Therefore, RDP / VAE must be stored in tightly closed containers or bags to prevent moisture penetration. please use it up in one go if possible after opening the container or bag , otherwise the bag or container should be properly sealed to prevent the powder from absorbing moisture in the air. In addition, storing the powder in a dry, cool space, ventilated area will help maintain its integrity.

Storage under pressure should also be avoided. Do not stack pallets on top of each other. RDP Powder storage must be protected from direct sunlight. Exposure to UV light can cause long-term degradation of the powder and reduce its performance in construction applications.

And please also note that the shelf life of redispersible latex powders is 6 months. Therefore, it is important to use the oldest stocks first to ensure that the powder is used within the recommended time.  The powder should be used as soon as possible in summer .

In addition to the above storage recommendations, RDP powders must be kept away from sources of ignition and flammable materials. Due to its chemical composition, RDP may cause a fire if exposed to open flames or sparks. Therefore, powders must be stored in designated areas away from potential fire risks.

When transporting RDP powders, the use of sealed packaging and conspicuous labeling helps to ensure that the powder is transported and stored safely.

Finally, it is important that RDP powders are checked regularly. This includes moisture, clumping or degradation and ensuring that storage areas are clean. Dry, ventilated storage away from direct sunlight extends the shelf life and improves the performance of RDP powders.

In summary, proper storage of dispersible latex powder is important to maintain its effectiveness and quality. By following recommended storage methods, including keeping the powder in a dry, cool and light protected area. Compliance with safety requirements for handling and transportation will ensure that redispersible polymer powders remain in optimal condition for construction applications.
