Product Details

Product Description

Redispersible Polymer Powder, also called Hydra (RDP), is a free-flowing and water-soluble white powder. It is obtained from vinyl acetate-ethylene through a spray-drying process. Hydra (RDP) can enhance the mortar adhesion, cohesion, and bonding strength. It also improves workability, durability, abrasion resistance, wear resistance, and load-bearing capacity. Adding Hydra (RDP) also enhances the mortar’s wetting and water-retention property

Product Highlights

  1. Film formation. RDP is an organic adhesive. It forms a thin but high-tension, high-viscosity film on substrates, to prevent moisture.
  2. Great bond strength. The high polymer binder can significantly improve the adhesion and bonding strength of the mortar.
  3. Excellent workability. Hydra (RDP) can make the mortar easy to mix and smooth to apply, reducing the working time and labor cost.
  4. Excellent flexibility. Hydra (RDP) is a thermoplastic resin. It allows the mortar to adapt to the changing in the external environment. So effectively prevents the mortar from cracking due to the temperature changes.
  5. Excellent water resistance. The delicacy developed modified formula of Hydra ET6010H effectively prevents moisture intrusion. Just a thin layer, can form an effective waterproof barrier.
