Re-dispersible Polymer Powder(RDP)

MikaVAE™ Redispersible polymer powder plays an important role in modern construction because of its strength, durability, moisture resistance, and low maintenance properties.

RDP Profile

Product overview

MikaVAE™ Redispersible polymer powder (RDP) is a free-flowing, white powder obtained by spray-drying of an aqueous vinyl acetate-ethylene(VAE) copolymer dispersion, uses polyvinyl alcohol as a protective colloid., It offers all the advantages of a free-flowing powder additive such as ease of transportation, storage, and handling.

MikaVAE™ Redispersible polymer powder (RDP) is usually used together with MikaZone™ cellulose ether products to modify the property of building mortars.

It can be applied in a variety of applications in the construction industry to improve the key properties of cement and gypsum-based formulations.

MikaVAE™ RDP product packaging


MikaVAE™ polymer powders combine the adhesion of vinyl acetate with the flexibility of ethylene. The powders can be quickly redispersed into an emulsion after contact with water, and the emulsion has the same properties as the original dispersion. When the powder is emulsified and dispersed in water, it will form a polymer film after the water evaporates, This film has high bonding ability and unique properties, such as high flexibility, high heat resistance, and high adhesion to the various substrates.


MikaVAE™ redispersible polymer powers are especially suited for the construction industry, working as an important additive in dry mix mortar. It can empower the mortar with improved adhesion, flexural strength, deformability, abrasion resistance, and easy construction.

Applications in the construction industry including:

• Tile adhesive • Tile grout • Wall putty • Repair mortars • EIFS mortars • Self leveling compounds...


• Better water retention & extended open time.

• Better strength development & cohesion of the mortars.

• Enhanced adhesion to various substrate.

• Enhanced tensile strength & crack-resistance.

• Increased impact and abrasion resistance.
