In the ever-evolving construction industry, the demand for high-performance building materials is paramount. Redispersible Polymer Powder (RDP) has become an indispensable additive for enhancing the properties of dry-mix mortars. Among the various grades available, the FORAWAD FWD 1200 stands out as a highly versatile and efficient vinyl acetate-ethylene (VAE) copolymer powder, designed to meet the rigorous demands of diverse construction applications.
Product Overview and Technical Specifications
The FWD 1200 is a water-soluble, spray-dried powder derived from a vinyl acetate-ethylene copolymer. It is formulated with polyvinyl alcohol as a protective colloid, ensuring excellent redispersibility in water to form a stable emulsion. This property is crucial for creating a strong, coherent film that bridges the gap between mortar components and various substrates.

Key Performance Advantages
The FWD 1200 is engineered to impart a host of superior properties to cement-based and gypsum-based mortars, making it a multifaceted tool for construction professionals.
1. Enhanced Mechanical Strength
The polymer film formed upon redispersion significantly increases the adhesive and cohesive strength of mortars. This leads to higher flexural strength, making the final material more resilient to cracking and structural stress.
2. Superior Workability and Rheology
One of the standout features of the FWD 1200 is its ability to improve the workability of mortar blends. It provides excellent rheology, allowing for smooth application, better trowelability, and easier handling. This reduces labor effort and enhances the quality of the finished surface.
3. Improved Water Retention and Open Time
By optimizing the water retention capability of the mix, the FWD 1200 extends the open time. This gives workers more time to adjust and place materials, ensuring a strong bond is achieved even under challenging environmental conditions.
4. Excellent Durability
Mortars modified with this RDP exhibit great durability and abrasion resistance. The polymer matrix also contributes to water resistance and low water uptake, protecting the structure from moisture-related damage and extending its service life.
Recommended Applications
The FWD 1200 is a multi-purpose grade, making it a valuable addition to a variety of dry-mix formulations. While it excels in several areas, it is particularly recommended for the following applications:
