High-Performance Redispersible Polymer Powder (RDP/VAE) for Modern Construction
InnoNew® Redispersible Polymer Powder (RDP), also known as VAE powder, is a spray-dried polymer designed for dry mix mortar applications. When mixed with water, it re-disperses into a stable emulsion, forming a flexible polymer film that enhances adhesion, cohesion, and durability.
Our RDP powder is widely used in tile adhesive, wall putty, self-leveling mortar, EIFS, and waterproof mortar systems. It provides excellent workability, water retention, and crack resistance, making it essential for modern construction formulations.
