Dispersion/Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate and ethylene. It dissolves in water easily and quickly forms emulsion. Dispersion polymer powder gives the mortar higher flexural strength, excellent waterproofing property, improved workability, increased impact and abrasion resistance, durability, weather-ability, better deformability, increased adhesion to a variety substrates, improved wetting of the substrate, higher flexibility, increased impact and abrasion resistance, higher durability and freeze thaw resistance. It is suitable for tile adhesive/tile grouts, skim coat/ wall putty, adhesive and base mortar for EIFS (external insulation finish system), joint filler, decoration mortar
