WACKER Presents Novel Dispersion for Hydrophobic Construction Solutions.

Jump to the comments

At the European Coatings Show (ECS) 2017, WACKER, the Munich-based chemical group, will showcase a new polymeric binder for formulating two-component water repellent construction applications. In flexible sealing slurries, the hydrophobic VINNAPAS® 760 ED dispersion not only ensures excellent tensile adhesion strength after prolonged exposure to water and outstanding crack bridging, even at low temperatures. It also displays superb processing properties. The dispersion is thus ideal for use in waterproofing systems for indoor pools, basements and bathrooms.

VINNAPAS® 760 ED is a terpolymer based on vinyl acetate, ethylene and vinyl ester that finds use as a hydrophobic binder in two-component cementitious sealing slurries. A special feature of the dispersion is its vinyl neodecanoate component, which WACKER markets under the VERSA® brand. Together with ethylene, this considerably increases theelasticity of the end product. As a result, the coating is more extensible and very flexible even at low temperatures. Additionally, it is highly resistant to hydrostatic pressure.

As a mortar additive, VINNAPAS® 760 ED ensures outstanding crack bridging, both for static and dynamic cracks – even at exceptionally low temperatures down to -20 °C. Sealing systems based on VINNAPAS®760 ED thus achieve crack-bridging class O2 as per EN 14891. Thanks to the new dispersion, the end product bonds reliably and permanently to difficult substrates. VINNAPAS®760 ED is readily compatible with different types of commercially available cement. The high solids content of almost 60 percent moreover makes it possible to tailor the polymer /cement ratio to individual requirements without increasing the viscosity.

According to assessment by the German Federal Institute for Risk Assessment (BfR), the material is suitable for contact with drinking water, because it does not require any additional solvents, plasticizers or filmforming aids. Furthermore, the dispersion is manufactured without the use of alkylphenol ethoxylates (APEOs). VINNAPAS®760 ED has very little influence on cement setting behavior.

The new VINNAPAS® 760 ED dispersion is thus ideal for the formulation of two-component sealing slurries used, for example, to waterproof indoor pools, basements and bathrooms, as well as water pipes and sewers.
