What is FWD 1100 RDP?
FWD 1100 is a high-performance, water-soluble polymer powder produced by spray-drying a vinyl acetate-ethylene (VAE) copolymer. This process results in a fine, white, free-flowing powder that can be easily mixed into dry mortar formulations. Its core function is to re-disperse in water when the mortar is mixed, forming a flexible polymer film within the hardened matrix.
Typical Properties
| Property | Typical Value (FWD 1100) |
|---|---|
| Appearance | White flowing powder |
| Polymer Type | Vinyl Acetate-Ethylene (VAE) Copolymer |
| Protective Colloid | Polyvinyl Alcohol |
| Solids Content | ≥ 98% |
| Bulk Density | 400 – 550 g/l |
| Particle Size | approx. 80 μm |
| pH | 5.0 – 8.0 |
| Ash Content | 12 ± 2% |
| Minimum Film Forming Temp. (MFFT) | 4°C |
* Viscosity (50% water solution, 25°C) : 0.5 – 2.0 Pa·S
These properties, particularly the low film-forming temperature of 4°C, ensure that FWD 1100 can effectively create a continuous, reinforcing film even under normal ambient conditions.
Key Performance Benefits
When incorporated into cement- or gypsum-based mortars, FWD 1100 imparts several critical improvements:
- Exceptional Adhesive Strength — prevents delamination and failures
- Superior Flexibility & Crack Resistance — absorbs stress, enhances flexural strength
- Enhanced Workability & Open Time — smoother application, extended adjustability
- Improved Durability — reduces water uptake, increases freeze-thaw resistance
- Excellent Rheology — stable, consistent mortar performance
Recommended Applications
FWD 1100 is particularly recommended for applications where strong bonding and flexibility are paramount. Based on the official data, the star ratings indicate the level of suitability:
⭐ 4-star applications — Tile Adhesives and EIFS — are where FWD 1100 delivers the most outstanding performance.
Application Highlights
- Tile Adhesives: Ideal for bonding all types of tiles, including large-format and low-absorption porcelain. Ensures a long-lasting, secure bond for interior and exterior projects.
- EIFS: Critical for adhesive mortars and basecoat renders, providing strong adhesion to insulation boards and the necessary flexibility and impact resistance for the protective outer layer.
- Cement-Based Plasters: Improves substrate bond and significantly reduces shrinkage cracks, leading to a more stable, high-quality finish.
- Wall Putties: Enhances adhesion and cohesion of putty layers, ensuring a smooth and durable surface ready for painting or decoration.
Packaging & Storage
To maintain quality and ensure long shelf life, store the product in a cool, dry warehouse, away from direct sunlight, rain, and sources of heat.
