vita RDP® Redispersible Polymer Powder

vita RDP® is a spray-dried, free-flowing powder that redistributes into an emulsion when mixed with water. It forms a flexible and adhesive polymer film upon drying and offers good storage stability and flowability. The powder can be pre-mixed with cement, fillers, and additives, simplifying on-site preparation and improving construction efficiency and quality. Product Composition Polymer Resin: Core functional component. Additives: Enhance performance and application range. Protective Colloid: Hydrophilic coating, usually polyvinyl alcohol. Anti-caking Agent: Fine mineral filler to prevent caking. vita RDP® redispersible polymer powder is classified into four grades: 8011: White or light yellow, free-flowing powder. Solid content ≥98.0%, ash content 18% ±2, bulk density 500−600 g/l, particle size ~80 μm, pH value 5.0-8.0, minimum film-forming temperature 0℃, glass transition temperature 16℃, non-hydrophobic. 8012: White or light yellow, free-flowing powder. Solid content ≥98.0%, ash content 15% ±2, bulk density 500−600 g/l, particle size ~80 μm, pH value 5.0-8.0, minimum film-forming temperature 0℃, glass transition temperature 3℃, non-hydrophobic. 8013: White or light yellow, free-flowing powder. Solid content ≥98.0%, ash content 12% ±2, bulk density 500−600 g/l, particle size ~80 μm, pH value 5.0-8.0, minimum film-forming temperature 0℃, glass transition temperature -8℃, non-hydrophobic. 8513: White or light yellow, free-flowing powder. Solid content ≥98.0%, ash content 12% ±2, bulk density 500−600 g/l, particle size ~80 μm, pH value 5.0-8.0, minimum film-forming temperature 0℃, glass transition temperature 3℃, hydrophobic. 4. Applications vita RDP® is used as an additive in building materials, enhancing modified polymer mortars for improved adhesion, flexibility, and durability. It is suitable for tile adhesives, bonding mortars, plasters, self-leveling mortars, putties, decorative plasters, dry coatings, joint fillers, repair mortars, and waterproof sealants. 5. Product Benefits Adhesion: Enhances bonding strength. Workability: Improves workability with micro-bubbles. Flexibility: Increases flexibility and crack resistance. Abrasion Resistance: Enhances surface strength. Water Resistance: Improves water resistance and prevents leaks. Hydrophobicity: Reduces efflorescence and alkali discharge, enhancing aesthetics.
