Redispersible Powder (RDP), also known as redispersible powder, is a revolutionary additive in the construction industry. This polymer-based powder significantly enhances the properties of cement mortars, wall putty, and other construction materials. Developed by Hebei Jingzuan Chemical Technology Co., Ltd., RDP is engineered to improve bonding strength, durability, and workability in various applications. Below, we explore its features, technical specifications, and real-world applications in detail.

Redispersible powder is a versatile additive designed to enhance the performance of construction materials. When mixed with water, it reconstitutes into a polymer dispersion, providing exceptional bonding properties. This makes it ideal for applications such as cement mortar, wall putty, EIFS (Exterior Insulation and Finish System) mortar, and tile bonding mortar. Its ability to improve the coating and spreading rate of mortars and putty, while also reducing cracking and increasing structural strength, has made it a preferred choice in modern construction projects.
Redispersible powder offers a range of benefits that make it indispensable in construction. Here are some of its standout features:
| Parameter | Specification |
|---|---|
| Chemical Name | Redispersible Powder |
| Molecular Formula | (C₂H₄)ₓ(C₄H₆O₂)ᵧ |
| Moisture Content (%) | ≤5 |
| Residue (Ash) (%) | 12–25 |
| Fineness (Mesh) | 80–120 |
| Minimum Film-Forming Temperature (℃) | 0–5 |

RDP is widely used in various construction scenarios, including:
Ensuring the quality of redispersible powder is critical for its performance. Two common methods to verify its quality are:

1. Prepare a small amount of RDP solution. 2. Pour it onto a clean tile and let it dry completely. 3. A hard-to-remove VAE (Vinyl Acetate-Ethylene) film should remain on the tile’s surface, indicating proper bonding.

1. Mix a small quantity of RDP solution and pour it into a glass dish. 2. Allow it to dry, forming a smooth, even film. 3. Tear the film from the bottom and stretch it. It should be elastic and tensile, confirming its dispersibility.
