RDP Powder for Crack Filling
WOTAIchem is a professional re-dispersible polymer powder supplier for crack fillers. Our high-quality products are tailored to all construction and repair projects.
Redispersible polymer powder is also called VAE RDP powder. It’s obtained by spray drying water-based emulsion. Mostly based on vinyl acetate-ethylene (VAE). This type of free-flow organic polymer power can quickly dispersed in water. And it forms a film when water evaporates. This film is a highly efficient organic binder, it can bond mortar to different substrates.
-Reinforce mortar structure with excellent adhesion.
-Good rheology and improved workability.
-Achieve abrasion and sag resistance.
-Good water retention rate and open time.
Discover the Power of Redispersible Polymer for Crack Filling
Concrete cracks will form over time. Due to various circumstances, such as shrinkage, extreme temperature changes, excessive load or weight, or water intrusion. This is where you need RDP powder. It’s an essential ingredient for your crack-filling material.
RDP powder in crack filling compound improves the adhesion to concrete surfaces. And it adds flexibility to crack filler material, ensuring your crack filler stays securely in place. RDP powder is also resistant to sag, impact, and environmental factors. So, your cracking filing is powerful against extreme weather impacts.

Exploring 5 Additional Applications Beyond Crack Filling
WOTAIchem redispersible polymer powder (VAE RDP) powder works well in different building materials. Discover the power of RDP powder in the following application scenarios.
RDP powder in dry mixed mortar is simple to use. It dissolves quickly in cold water. Its high water retention rate avoids fast water evaporation.
RDP powder maximizes the moisture content in the wall putty mixture. It effectively prevents sag and shrinkage. For both indoor and outdoor walls.
RDP powder in tile adhesive provides good lubricity and plasticity, making it easier and faster to apply. The adhesive power attaches tiles securely.
RDP powder is frequently used in the base coat and adhesive coating of ETICS. It enhances adhesion and reduces air entry and moisture absorption.
RDP powder in a self-leveling mixture effectively prevents material from settling at the bottom. Its water retention feature benefits the fluidity.

RDP (Redispersible Polymer Powder) Crack Fillers:
RDP powder has superior adhesion to boost a strong and durable bond. It also has good plasticity and flexibility, which can effectively minimize crack formation.
Crack filler with RDP powder features good water resistance. It allows easy application in different projects.
Traditional Crack Fillers:
The adhesion of the traditional crack fillers varies differently. Sometimes, you may need extra dosage for other products. The traditional types of crack fillers are generally less flexible; there is a chance of cracks formation.
The traditional crack fillers may not have the same level of water resistance as RDP powder. Application methods may also vary.
WOTAIchem RDP crack filler stands out with superior qualities. It offers better adhesion, flexibility, water resistance, durability, and ease of use compared to traditional ones. Contact us today to learn more about RDP power!
