At the European Coatings Show 2009, Wacker has launched ETONIS polymer binders for use in infrastructure projects. ETONIS brand polymers are meant to enhance sprayed concrete for applications in mining, tunneling, road and underground construction. As the tunnel is driven, the polymer-modified concrete is sprayed onto the walls primarily to consolidate loose rock. It also provides a barrier against water seepage, and reduces the amount of additives required in the formulation. Since the polymer improves the concrete's adhesion, there is less rebound when it is sprayed onto the tunnel wall. That reduces both material consumption and transportation and disposal costs.
