vAE – ThE TEChNOLOGY dEfINING TOdAY ANd ShApING TOMORROW WACKER developed VAE technology in the mid-60s and began industrial scale production in 1966. Today, WACKER still pioneers the technology’s development and is responsible for one of the largest share of global VAE production. 6 The High-Performance Choice Vinyl acetate-ethylene (VAE) technology is increasingly replacing other technologies due to the continuous refinement of its core benefits, which include high adhesion, broad formulation flexibility, high setting speed and excellent cost-in-use. Recent developments in the VINNAPAS ® range have extended its applicability beyond the traditional paper and packaging, wood working, flooring and construction markets to new markets, such as pressure-sensitive labeling and automotive adhesives. The VINNAPAS ® range offers a broad selection of products to enable adhesives manufacturers to formulate the right balance of cost and performance for their end-customer’s adhesive application. Designed with Market-Leading Insight Due to their copolymer composition, vinyl acetate-ethylene copolymer dispersions enable the formulation of adhesives with low migration potential and reduce or avoid the need for a film-forming agent. VINNAPAS ® dispersions are stabilized with colloid systems and/or surfactant systems. The most common colloid system used in adhesive applications is poly(vinyl alcohol), a large water-soluble molecule. It provides the optimum rheology for a wide range of adhesive applications, e.g. paper and packaging applications. Surfactant stabilized dispersions typically show higher shear thinning than PVOH stabilized dispersions. Their advantages include better adhesion to plastics, clearer films, higher water resistance and good spray ability. Superior Properties Enabling Long-Lasting Adhesives VINNAPAS ® VAE dispersions feature an excellent adhesion and cohesion balance as well as high degrees of wet tack. In addition, they bond to a wide variety of substrates. Specific VINNAPAS ® products also offer the advantage of being suitable for both roller applications and the nozzle technology that is replacing the roller technology in many markets. Environmental and Health Impact All of our VINNAPAS ® dispersions for the adhesives market are water-based, and produced without organic solvents or plasticizers. Furthermore, APEO surfactants are not used as stabilizers in the adhesive dispersion range. These characteristics put them in line with evertightening consumer health legislation, especially for food packaging, – in this sector, the migration of constituents from packaging materials into food is under intense scrutiny.
VINNAPAS ® VAE Dispersion Key Benefits • Future-proof technology based on vinyl acetate monomer and ethylene feedstocks • Heat resistance, high degrees of wet tack, fast setting speed • No need for plasticizer in the formulation, thus allowing adhesives with low migration potential 7
