VAE Polymer Powder
VAE Polymer Powder
VAE is a copolymer of vinyl acetate and ethylene, sold in the form of an oil-soluble water-based emulsion (construction adhesives) and as a free-flowing redispersible powder for application to construction materials such as mortars, plasters, and insulation systems.vae polymer powder It is characterized by its excellent moisture resistance, flexibility, and improved tack. It also offers good adhesion to non-porous surfaces. It can be added to gypsum and cement based plasters, mortars, and slurries for the purpose of increasing their cohesive strength, bond strength, and water proofing capabilities. It is commonly used in tiling and flooring applications, especially as a tile’s adhesive, but it is increasingly being employed in wall putty and gypsum plasters as well.
The global market for VAE is driven by the rising construction activities in both residential and commercial sectors, particularly in the Asia Pacific region.vae polymer powder This is due to the growing population and improving living standards, as well as increased infrastructure spending in various countries across the region. This in turn is expected to drive the demand for various construction chemicals, including vae polymer powder, over the forecast period.
However, stringent environmental regulations imposed by different governmental bodies on the VOC content of products are expected to restrict the growth of the market.vae polymer powder In addition, the high price of the product also acts as a deterrent for some potential customers.
Nevertheless, the development of technology that makes the product less costly is expected to boost the growth of the market in the long run. In addition, the rising concerns about health hazards associated with the use of formaldehyde has also resulted in a shift towards the use of VAE made without formaldehyde.
In terms of product type, VAE re-dispersible powders are preferred in the market. These are white, free-flowing powders that can be redispersed into water to re-form a stable latex emulsion. They are easy to ship, store (excellent storage stability), handle, and dry-mix compared with VAEs in an emulsion form.
VAE-RDPs are usually used as a modifier for cement and plasters to improve their workability, water retention, plasticity, and dispersibility, and as a binder resin for inorganic binder such as gypsum and hydrated lime in construction adhesives. They also help improve flex strength, stability, impact resistance, and abrasion resistance. They are often combined with other admixtures such as fly ash, silica sand, and light aggregate to improve their performance. They can also be used as an additive for the oil and gas field cementing operations to enhance rheological properties, improve pore structure, control fluid-loss, and increase durability of mud and grout compositions. VAE-RDPs also offer benefits when mixed with oil field slurries, such as by improving particle-to-particle bonding and by decreasing permeability.
