RDP(Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. It dissolves in water easily and forms emulsion quickly , RDP could offer strong adhesive and stretching force to improve the workability, flexibility and water-proofing of the materials. This VAE Re-Dispersible Polymer Powder Used in construction from Landcel uses polyvinyl alcohol as a protective colloid. By adding landcel RDP, the performance of mortar with cement or gypsum can meet the needs of various constructions.
VAE Re-Dispersible Polymer Powder (RDP)is produced by spray-drying and water-based emulsion, mostly based on vinyl acetate and acrylic acid, dissolves in water easily and quickly forms emulsion.The main specification is as below, and Ash content , Film tempreture is the key properties.
