Redispersible polymer powder is a polymeric emulsion powder that, when mixed with the water, redisperses in the water to form new emulsions. When added to mortars, redispersible polymer powder increases cohesion, bond strength, and flexibility of mortars. Redispersible polymer powder improves pot life, workability, water-retention property, adhesion force, abrasion resistance, and sag resistance.
The global redispersible polymer powder market has been segmented based on polymer, application, and end-user. In terms of polymer, the market has been classified into acrylic, vinyl acetate ethylene (VAE), vinyl ester of versatic acid (VeoVa), styrene butadiene, and others. Acrylic was the leading segment of the global redispersible polymer powder market in 2017. Acrylic-based redispersible polymer powder offers good cohesion, excellent flexibility, and waterproofing properties. It has high abrasion resistance and hydrophobicity. It is also employed to heal cracks and offer excellent adhesive strength to different surfaces. Acrylic-based redispersible polymer powder is preferred for use in cement-based products, due to its excellent hydrolysis resistance and properties such as flexibility, clarity, chemical stability, water resistance, resistance to alkaline environments, versatility, and rheology. VAE-based redispersible polymer powder is being highly adopted. The powder has high saponification resistance and a wide range of glass transition temperatures (Tg). It has good bonding and high flexibility. These properties are raising the demand for VAE-based redispersible polymer powder across the globe.
In terms of application, the global redispersible polymer powder market has been segregated into mortars & cements, tile adhesives & grouts, insulation & finish systems, plasters, self-leveling underlayment, and others. Mortars & cements is likely to be the leading application segment of the global market during the forecast period. Redispersible polymer powder is extensively used in the production of cement repair mortars and concrete in the building & construction industry. Redispersible polymer powder improves workability and other important mechanical properties such as tensile strength, compression strength, and flexural strength, and transversal deformation of building products.
Additionally, it offers various other benefits such as high adhesion, abrasion resistance, plasticity, and slip resistance to building products exposed to conditions involving thermal or mechanical stress. Demand for redispersible polymer powder in tile adhesives & grouts and insulation & finish systems segments is expected to rise significantly during the forecast period. Modern ceramic tiles, especially thin-bed tiles, when modified with redispersible polymer powder, attain improved adhesion, flexibility, and workability. Redispersible polymer powder also enables use of non-porous or large-format tiles on difficult substrates, such as wood or other tiles, due to its superior adhesion. Redispersible polymer powder is used in external insulations and finishing systems (EIFS). It enhances the performance of EIFS mortars, providing high tensile strength, superior adhesion to substrates, and greater durability under varied climatic conditions.
