Vinyl acetate ethylene copolymer emulsion is a copolymer of vinyl acetate and ethylene. It has been formed as a strong base adhesive, providing unique features like strong initial adhesion, elevated soggy tack, excellent barrier to creeping, water/alkali resistance, enhanced thickening responding and reliable handling. EVA copolymers, typically containing 15–40% of vinyl ester content, and have been recognized as crucial flow lifters for crude oils and medium distillates. However, due to its polarity, only solutions of EVA copolymers with a polymer content of at most 10–15% are still liquid in aromatic solvents at room temperature.
Increased application in the construction sector as concrete mortars, smoothing compounds, decorative plasters, joint fillers, flooring compounds, and construction adhesives, has stimulated growth in the demand for vinyl acetate ethylene copolymer. It is used as a powder which is redespersible. Redespersible powders are genarally recognized as polymer powders which can re-disperse back into fresh mixtures with the same properties as the initial copolymer emulsions in water. However, greater demand for vinyl acetate copolymer powder based on acrylic, forms a major hindrance for the expansion of the vinyl acetate ethylene copolymer market.

However, Vinyl Acetate Ethylene Copolymer Powder is is treated with chemical preservatives, which include creosote and chromated copper arsenate. These chemicals can affect the soil and also kills insects, plants, and small animals. This further restricts the use of Vinyl Acetate Ethylene Copolymer Powders in variousapplications, which is anticipated to hamper the market growth.
