Redispersible Powder (RDP) - HEBEI JINGZUAN | Bonding Strength, Crack Resistance

Product Features

Redispersible Powder (RDP) is a polymer-based additive designed to optimize the properties of construction materials. Its unique formulation allows it to re-disperse in water, creating a uniform film that enhances adhesion and durability. Key features include:

• Exceptional Bonding Ability: Ensures strong adhesion between materials, reducing the risk of delamination.
• Improved Workability: Enhances the coating and spreading rate of mortars and putty.
• Crack Resistance: Minimizes cracking in structures, extending their lifespan.
• High Strength: Increases the mechanical strength of construction materials.

Advantages of RDP in Construction

Integrating Redispersible Powder into construction projects offers numerous benefits. It is particularly effective in:

• Cement Mortar: Enhances cohesion and reduces shrinkage cracks.
• Wall Putty: Provides a smooth, durable finish with excellent adhesion.
• EIFS Mortar: Improves flexibility and weather resistance.
• Tile Bonding Mortar: Ensures strong adhesion and prevents tile slippage.
• Tile Seam Filling: Offers superior gap-filling properties and durability.

By incorporating RDP, contractors can achieve higher-quality finishes while reducing material waste and labor costs.

Quality Check Methods

To ensure the quality of Redispersible Powder, HEBEI JINGZUAN provides simple yet effective testing methods:

Method No. 1: Bonding Ability Check

1. Prepare a small amount of RDP solution.

2. Pour it onto a clean tile surface and let it dry completely.

3. A film of VAE should form on the tile. If the film is hard to scrape off, the product is qualified.

Method No. 2: Film and Dispersibility Check

1. Mix a small amount of RDP solution and pour it into a glass dish.

2. Allow it to dry, forming a smooth, even film.

3. Tear the film and stretch it. It should be elastic and tensile.

A video demonstration is available to guide users through the quality check process.
