Industry grade redispersible polymer with Chinese factory sources
1. In ETICS/EIFS (External Thermal Insulation Composite Systems / External Insulation and Finish Systems), Redispersible Polymer (RPP / RDP) 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 RDP (rigid, semi-flexible, flexible, and hydrophobic), their common characteristics, and their different applications in ETICS/EIFS.
| 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. |
Key benefits of Semi-Flexible [Redispersible Polymer] for ETICS/EIFS
Key Properties: [redispersible polymer] balanced combination of tensile adhesion strength,moderate impact resistance,and flexural capability. (Medium Tg,approx.0°C to 15°C)
Standard Adhesive Mortars: redispersible polymer widely used for standard EPS(Expanded Polystyrene)board adhesives where moderate flexibility and cost-effectiveness are balanced.
General Base Coats(Ground Floor or Standard Facades): redispersible polymer provides sufficient crack resistance for standard climate zones without extreme temperature swings.
Key Advantage:Excellent all-rounder offering a compromise between high strength and strain tolerance.
Packages
● 25kg net weight per plastic/paper bag, ● 500kg per jumbo bag on a pallet, Packing on request, ● 20'FCL: 520 bags=13 tons,
● 4. 40'HQ FCL: 1120 bags=28 tons, ● Shipping time: 5-10 days.
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)
