Basic details of VAE Re-dispersible Polymer Powder

VAE (Vinyl acetate-ethylene) re-dispersible polymer powder is a type of polymer powder that is produced by spray-drying an aqueous emulsion of a copolymer of vinyl acetate and ethylene. 

It is commonly used as a binder in construction applications, such as in the production of dry-mix mortars, grouts, and cementitious adhesives.

The powder is white or off-white in color, with a particle size ranging from 10 to 100 microns. It has a low glass transition temperature, which allows it to remain flexible and elastic at low temperatures. 

The powder is soluble in water, and when added to water, it forms a stable dispersion that can be easily mixed with other dry ingredients.

The properties of VAE re-dispersible polymer powder can be tailored to meet specific application requirements by adjusting the copolymer composition, polymerization conditions, and spray-drying parameters. 

The powder can be modified with various additives, such as plasticizers, crosslinking agents, and pigments, to enhance its performance and appearance.

Overall, VAE re-dispersible polymer powder is a versatile and cost-effective binder that provides improved adhesion, flexibility, and durability to construction materials.
