Adhesion
Improves bonding between mortar and substrates, helping provide stronger and more reliable adhesion in tile adhesives, repair mortars, EIFS/ETICS and other construction applications.
Redispersible latex powder
RDP/VAE
Redispersible Polymer Powder (RDP) is a polymer-based functional additive designed for cement- and gypsum-based dry-mix construction materials. It is primarily used in tile adhesives, EIFS/ETICS systems, repair mortars, waterproof mortars, self-leveling compounds, and other dry-mix formulations. RDP improves adhesion, flexibility, cohesion, crack resistance, and durability by forming a polymer film within the hardened mortar. It provides reliable performance modification for manufacturers seeking stronger bonding, improved mechanical properties, and long-term durability in construction formulations.
