Wide Range of RDP powder
1. RDP powder is always combined with cellulose ethers and other additives to improve the properties and performance of cement-based or gypsum-based mortars, such as better water retention, open time, better workability, increased adhesion to various substrates, and higher flexural strength and flexibility.
2. RDP powder uses widely in different ways of constructive drymix mortat or additives. Details of how the four primary Re dispersible Polymer Powder types (Rigid, Semi-Flexible, Flexible, and Hydrophobic) are utilized across various dry-mix mortar applications:
| RDP Category | Core Mechanical Focus | Key Advantage in Mortar | Typical Dry-Mix Mortar Application |
|---|---|---|---|
| Flexible | Extreme Elasticity & Elongation | Dynamic crack bridging & shock absorption | C2/S1/S2 Tile Adhesives, EIFS Anti-crack Renders, Waterproof Slurries |
| Semi-Flexible | Balanced Elasticity & Cohesion | Cost-effective, multi-purpose performance | C1 Tile Adhesives, Wall Putties, Board Bonding Mortars |
| Rigid | Compressive & Shear Strength | High surface hardness & load-bearing capacity | Heavy-Duty Screeds, Repair Mortars, Non-Shrink Grouts |
| Hydrophobic | Water Repellency & Low Absorption | Prevents moisture ingress & efflorescence | Waterproof Tile Grouts, Exterior Facade Renders |
Key Benefits of Flexible RDP Powder in Drymix Mortar
The flexible polymer film acts as an internal elastomer spring within the rigid cement matrix, dissipating internal shear stresses and preventing crack propagation.
● S1 / S2 Highly Deformable Tile Adhesives: Essential for large-format slabs, outdoor tiling, and substrates subject to thermal expansion (e.g., heated floors, balconies).
● Embedded Surface Coats (Reinforcement Mortars) for EIFS: Absorbs wind loads and thermal stresses acting on external insulation systems.
● Flexible Waterproof Slurries (1K / 2K Mortars): Bridges micro-cracks in concrete basements, water tanks, and wet rooms.
● Plywood / Metal / Tile-on-Tile Base Mortars: Adheres reliably to non-porous or deformable substrates.

Storage
Please Store in a cool, dry place. Dry Conditions: Keep relative humidity (RH) below 50%–60%. RPP is thermoplastic and hygroscopic; elevated temperatures combined with moisture will cause the powder to soften and block (form hard clumps)
Avoid Direct Sunlight: Keep stored bags away from direct sunlight, rain, and heating sources (e.g., radiators or steam pipes)
Keep Sealed: Always store in original, unopened multi-layer paper bags with PE inner liners. If a bag is opened, seal it tightly immediately after use.
