Vinyl Acetate-Ethylene (VAE) based · High-flexibility grade for advanced dry-mix mortars
🧪 MFFT 4 °C
⚙️ Solids ≥98%
🏷️ PVA protective colloid
FORAWAD FWD 5010 is a specialized, vinyl acetate-ethylene (VAE) based Redispersible Polymer Powder (RDP) engineered to enhance the mechanical properties and workability of dry-mix mortars. As a free-flowing white powder, it is designed to redisperse in water, forming a stable polymer film that fundamentally bridges the gap between rigid inorganic materials and the need for flexibility and adhesion in modern construction applications.
Key Technical Specifications
FWD 5010 is characterized by a set of consistent, high-quality technical parameters that define its performance in mortar formulations.

| Polymer Type | Vinyl Acetate-Ethylene (VAE) Copolymer | Provides a balance of flexibility, adhesion, and water resistance. |
| Protective Colloid | Polyvinyl Alcohol (PVA) | Critical for the powder's ability to redisperse in water. |
| Solids Content | ≥98% | High active polymer content ensures formulation efficiency. |
| Bulk Density | 400-550 g/l | Contributes to easy handling and uniform mixing. |
| Particle Size | 80 μm | Optimized for rapid and complete dispersion. |
| pH | 5.0-8.0 | Compatible with the alkaline environment of cement-based systems. |
| Minimum Film-Forming Temp (MFFT) | 4 °C | Allows for film formation at relatively low temperatures. |
Technical Benefits in Mortar Systems
The integration of FWD 5010 into cementitious and gypsum-based mortars delivers a suite of performance advantages:
- Enhanced Adhesive Strength: The polymer film acts as a secondary binder, creating a dense, cohesive network. This provides strong, durable bonding to a variety of substrates, including challenging, low-porosity surfaces, effectively preventing delamination and hollow spots.
- Superior Flexibility and Crack Resistance: The elastic nature of the VAE copolymer film imparts flexibility to the rigid mortar matrix. This allows it to absorb and dissipate internal stresses from temperature fluctuations, substrate movement, and shrinkage, significantly enhancing the material's resistance to cracking.
- Improved Workability: FWD 5010 improves the rheology and lubricity of fresh mortar. This results in easier application, better spreadability, and extended open time, providing construction workers with more time for precise placement and adjustment.
- Durability and Water Resistance: By filling the capillary pores of the mortar, the polymer film reduces water penetration. This creates a denser, more impermeable structure with superior abrasion resistance and long-term durability, even in wet or demanding environments.
Primary Applications
FWD 5010 is a highly adaptable grade suitable for a wide range of high-performance construction materials. Its application is particularly well-suited for scenarios demanding high flexibility and strong adhesion.
