Discover WACKER’S Long Association with VAE

WACKER scientists started researching polymer binders back in the 1920s. From the 1960s on, they set out to develop copolymer dispersions based on vinyl acetate and ethylene. VAE copolymers are still the main polymer base for both dispersions and dispersible polymer powders. Explore how WACKER’s VINNAPAS® technology became a benchmark for today’s vinyl acetate-ethylene (VAE) dispersions.


1938 Poly(Vinyl Acetate) Dispersion Production Starts On An Industrial Scale at our Burghausen site in Germany with VINNAPAS® H 60, a poly(vinyl alcohol)-stabilized dispersion for wood glue that had been developed in the laboratory the previous year. Following positive customer feedback, up to 25 metric tons of this dispersion are produced and delivered to the adhesives industry every month.
1949 VINNAPAS® Makes Dispersion-Based Paints Possible and marks a breakthrough in the formulation of highly efficient paints.
1957 A new era begins with VINNAPAS® dispersible polymer powders
when the first spray drying tower is commissioned at our Burghausen site for the production of VINNAPAS® dispersible powders. For the first time ever, a free-flowing dispersible polymer powder has been manufactured by spray drying. The direct oxidation of ethylene to acetaldehyde is a significant milestone. Filed for patent protection, award-winning and licensed worldwide, it finds its way into the annals of WACKER’s history.

The Development of VAE Technology Marks a New Era and Is an Important Milestone in the History of Dispersions. The innovative technology has been continually perfected ever since, and has been successful all over the world. Today, WACKER is a global market leader and a driving force behind innovation in copolymer dispersions, which are essential components in many modern sustainable applications.
1964 Waterborne Adhesive Dispersions Start their Long and Glorious Careerwith WACKER’s development of the first terpolymer VINNAPAS® dispersions with vinyl chloride, specifically as binders for construction applications. In 1964, copolymer EP dispersions for waterborne adhesives are launched onto the market and enjoy an unparalleled meteoric rise.
1985 VAE as a Basis for Manufacturing Dispersible Powders is another milestone set in WACKER’s labs. For the first time, a dispersion based on VAE can be used to manufacture VINNAPAS® polymer powders. This marks the start of VAE’s spectacular success, not only in dispersions but also in dispersible polymer powders.
1998 The Joint Venture with Air Products and Chemicals (AP) lays the foundation for the global success of both WACKER and AP. The Air Products Polymers joint venture produces polymer dispersions for manufacturers of adhesives, nonwovens, technical textiles, carpets, paints, paper-board and construction products.
2008 Global VAE Player Extends its Regional Presence as WACKER acquires the share previously held by Air Products and Chemicals – and thus strengthens its global position and market leadership in all key markets. Two years later, in 2010, the first locally-produced dispersions are sold in China.
2013 The 75th Anniversary of VINNAPAS® Dispersions is celebrated with a spectacular exhibition in a freight container traveling around the world. Over a period of 13 months, the mobile showroom inspires more than 2,000 visitors at 15 events on 4 continents.
2014 100 Years of Wacker Chemie. Built on our heritage, inspired by innovation: WACKER has very longstanding expertise in silicone and polymer chemistry, and has relentlessly pushed back the frontiers in all kinds of industries. An ever-important aspect for WACKER is to keep improving its products by making them even more sustainable and user-friendly.
