Redispersible Polymer Powder

Redispersible Polymer Powder (RDP) is a versatile polymeric additive essential in dry-mix mortars. Key types include vinyl acetate-ethylene (VAE) for general bonding, acrylic for waterproofing flexibility, and vinyl acetate-versatate (VAE-VeoVa) for superior hydrophobicity. RDP enhances adhesion, flexibility, and cohesion in tile adhesives, exterior insulation systems (ETICS), self-leveling compounds, and repair mortars, ensuring durable construction performance.
