Brève introduction :
Are you looking for a reliable source of Redispersible Polymer Powder (RDP) to enhance your dry-mix mortar formulations? At RawChemicalMart, we supply high-performance VAE-based polymer powders designed to boost adhesion strength, flexibility, and workability.
Our RDP series (RC-504, RC-502, etc.) disperses rapidly in water, forming a durable polymer film. Whether you are producing C1/C2 tile adhesives, EIFS bonding mortars, or wall putty, our powders ensure your products meet international quality standards while optimizing your raw material costs.
Why Choose Our VAE Polymer Powder?
🧪 Superior Bonding Strength
Significantly improves tensile adhesion strength on difficult substrates (like smooth concrete or high-density tiles), preventing hollow drums and detachment.
🛡️ Enhanced Crack Resistance
Our RDP creates a flexible polymer bridge within the mortar matrix. This absorbs stress caused by temperature changes and shrinkage, effectively preventing wall cracking.
🧱 Excellent Workability
Acts as a rheology modifier to improve thixotropy and extend open time, making construction smoother and reducing labor intensity.
💧 Water Resistance
Reduces water absorption in the hardened mortar, making it ideal for wet areas and exterior applications.

Ordering & Handling FAQs
Q: What is the packaging and shelf life?
A: We define standard packaging as 25kg net weight per bag, packed in moisture-proof paper-plastic composite bags. The shelf life is 6 months under dry conditions (below 35°C). Note: If stored properly, the product may still be usable after 6 months pending a quality check.
Q: Can I get free samples for lab testing?
A: Yes! We understand the importance of formulation testing. We offer free 500g-1000g samples. You only need to cover the shipping cost.
Q: What is the Minimum Order Quantity (MOQ)?
A: Our flexible MOQ starts from 1 Pallet (approx. 500kg-1000kg) to help you run pilot tests before bulk purchasing.
Q: Handling Precautions?
A: RDP is a thermoplastic powder. Store in a cool, dry place away from direct sunlight. After opening, reseal unused bags tightly to prevent moisture absorption (caking).
