RD-Polymer Powder
RDP is a free-flowing powder produced by spray-drying polymer emulsions like VAE and acrylic.
edispersible polymer powder (RDP) enhances flexural strength, adhesion, and water resistance in cement-based mortars, improving crack resistance and workability for tile adhesives, renders, and self-leveling compounds.

Key Applications of RDP
Construction & Mortars
- Tile Adhesives → Improves bond strength, flexibility, and open time.
- Self-Leveling Compounds → Enhances flowability and crack resistance.
- Exterior Insulation Systems (EIFS/ETICS) → Boosts water resistance and durability.
- Repair Mortars → Increases adhesion and reduces shrinkage cracking.
Paints & Coatings
- Polymer-Modified Cement Coatings → Improves flexibility and waterproofing.
- Textured Finishes → Enhances workability and reduces cracking.
Gypsum-Based Products
- Joint Compounds & Plasters → Strengthens cohesion and reduces dusting.
Specialty Applications
- 3D Printing Mortars → Enhances layer adhesion and printability.
- Green Building Materials → Used in low-VOC, eco-friendly formulations.
