Various kinds of RD Powder with premium quality from Chinese factory
1. In ETICS/EIFS (External Thermal Insulation Composite Systems / External Insulation and Finish Systems), RD powder are essential functional additives. They modify cementitious mortars to meet the strict mechanical and environmental demands of exterior walls.
2. The following details the four main types of RD powder (rigid, semi-flexible, flexible, and hydrophobic), their common characteristics, and their different applications in ETICS/EIFS.
form.
3. We are a professional manufacturer of construction additives over 30 years. So we can provide various RD powder price for every customer to support your career.
| RDP Type | Primary ETICS Layer | Key Technical Function | Performance Benefit & Risk Avoidance |
|---|---|---|---|
| Rigid RDP | Adhesive Mortar (Masonry to Board) | Provides high initial grab & structural shear strength | Ensures firm anchoring of EPS/MW boards; unsuitable for base coats due to low crack resistance. |
| Semi-Flexible RDP | Standard Adhesive & Base-Coat Mortars | Balances tensile bond strength with moderate elasticity | Cost-effective all-rounder for standard facade systems under normal weather conditions. |
| Flexible RDP | Base-Coat / Reinforcement Render Layer | Superior elongation & dynamic crack-bridging capability | Absorbs severe thermal expansion/contraction & wind loads; prevents surface micro-cracking. |
| Hydrophobic RDP | Topcoat Render & Decorative Finish Mortars | Built-in water repellency & low water absorption | Prevents rainwater penetration, freeze-thaw damage, and efflorescence on exterior facades. |
Core benefits of Hydrophobic RD powder for ETICS/EIFS
Key Properties:Contains silicone or long-chain fatty acid modifications.Reduces capillary water absorption of the cured mortar without sealing off water vapor permeability(breathability).
Base Coats&Topcoats:Reduces rain penetration into the system,preventing freeze-thaw damage(spalling)and salt efflorescence.
Mineral Wool Insulation Systems:Mineral wool loses its thermal insulation value rapidly if wet.Hydrophobic base coats protect MW insulation from water ingress.
Key Advantage:Keeps the entire composite system dry,maintaining thermal insulation efficiency and long-term durability.
Package and Storage
| STORAGE GUIDELINES | |
|---|---|
| Dry Conditions | Store in a cool, dry place with relative humidity (RH) below 50%–60%. Note: RPP is thermoplastic and hygroscopic; elevated temperatures combined with moisture cause powder to soften and form hard clumps. |
| Sealing Requirement | Keep in original, unopened multi-layer paper bags with PE inner liners. Reseal opened bags tightly immediately after use. |
| Environmental Safety | Keep away from direct sunlight, rain, and heat sources (e.g., radiators or steam pipes). |
| PACKAGING & LOGISTICS | |
| Standard Packaging | • 25 kg net weight multi-layer paper-plastic bag • 500 kg jumbo bag on pallet (Customized packaging available upon request) |
| Container Loading (FCL) | • 20' FCL: 520 bags = 13 metric tons • 40' HQ FCL: 1,120 bags = 28 metric tons |
| Shipping Time | 5 – 10 business days |
