Superior quality of re-dispersible polymer powder
Hydrophobic Re-dispersible Polymer Powder (HRPP) is a free-flowing, white powder obtained by spray-drying an aqueous polymer dispersion (latex) that has been modified with hydrophobic monomers or additives. Upon contact with water, the powder redisperses into a fine polymer emulsion, which, after film formation and curing, provides a continuous hydrophobic polymer matrix within cementitious or gypsum-based materials.
Core Benefits of Hydrophobic Re-dispersible Polymer Powder (HRPP)
● Superior Water Resistance & Low Capillary Absorption
● High Adhesive & Cohesive Bond Strength
● Increased Flexibility & Crack Resistance
● Excellent weathering prevention of re-dispersible polymer powder
● Re-dispersible polymer powder can enhance Freeze-Thaw Durability
● Re-dispersible polymer powder provide excellent Workability & Application Properties
