MUNICH, Germany – Wacker Chemie AG has bestowed this year’s Alexander Wacker Innovation Award on Christian Daniels, John Boylan and Bruce Gruber. The WACKER researchers have developed two novel dispersions based on vinyl acetate-ethylene copolymers. These kinds of dispersions are increasingly replacing the established coatings for paper applications, especially in the United States. This year’s EUR 10,000 innovation award focused on product innovation.

The new VINNAPAS^® EF 101 and VINNAPAS EF 575 dispersions are used mainly as coating material in paper processing. The coating ensures that the print on cardboard packaging is particularly durable and vividly colored. Compared to the acrylate-based products often used up to now, VINNAPAS EF 101/EF 575 offers customers an alternative technology with significant cost advantages. The developers were able to modify the formulation of these dispersions such that it now has the same application-related properties as the materials previously deployed. Until now, the properties of vinyl acetate-ethylene-based dispersions differed from those of acrylate-based products, especially with regard to viscosity and heat resistance.
