Redispersible Polymer Powder (RDP)

Redispersible Polymer Powder (RDP)

CAS: 24937-78-8

Redispersible Polymer Powder (RDP) is spray dried redispersible emulsion powder, designed for the construction industry to enhance the properties of dry mortar blends, able to Redispersible in water and  react with hydrate product of cement / gypsum and stuffing, form composite membrane with good mechanics intensity.

Redispersible Polymer Powder RDP improves the important application properties of dry mortars, like longer opening time, better adhesion with difficult substrates, lower water consumption, better abrasion and impact resistance.

Tile Adhesive

• Good water retention: prolonged opening time will make tiling more efficient.
• Improved adhesion and sliding resistance: especially for heavy tiles.
• Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.

Cement Plaster / Dry mix mortar

• Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.
• Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.
• Increased water demand: increased open time, expanded spry area and more economical formulation.
• Easier spreading and improved sagging resistance due to improved consistency

Wall putty

• Water retention: maximized water content in slurry.
• Anti-sagging: when spreading a thicker coat corrugation can be avoided.
• Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,RDP can increase the mortar volume.

Exterior Insulation and Finish System ( EIFS )

• Improved adhesion.
• Good wetting ability for EPS board and substrate.
• Reduced air entrancement and water uptake.

Self-leveling

• Protection from water exudation and material sedimentation.
• No effect on slurry fluidity with low viscosity
