RD powder from Chinese fctory souce
1. RD powder (RDP), or redispersible polymer powder, is a water-soluble polymer made from ethylene vinyl acetate (EVA) polymer by spray drying. It is designed for the construction industry to enhance the performance of dry mortar mixtures.
2. Details of how the four primary RD 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 Hydrophobic RD Powder in Drymix Mortar
During drying, hydrophobic active groups orient toward the pore surfaces of the mortar matrix, increasing the contact angle of liquid water and drastically lowering the water absorption coefficient without blocking vapor permeability (breathability).
● CG2WA Premium Tile Grouts: RD powder imparts a strong water-beading effect, preventing water and stain absorption into narrow tile joints.
● Exterior Top-Coat Decorative Renders & Stuccos: RD powder protects exterior facades against heavy rain and dampness.
● Sealing Slurries & Waterproof Mortars: RD powder reduces capillary water absorption under hydrostatic pressure in bathrooms, pools, and basements.
● Concrete Facade Repair Mortars: RD powder blocks water-borne salts (chlorides/sulfates) from reaching interior steel reinforcement.

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)
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.
Avoid Direct Sunlight: Keep stored bags away from direct sunlight, rain, and heating sources (e.g., radiators or steam pipes)
