Waterproofing with bitumen is a widely used method in many countries.
The VINNEVA® brand comprises a range of polymer-based dispersions for the modification of bitumen emulsions. The dispersions are usually post-added to the bitumen emulsions.
VINNEVA® dispersions are based on WACKER’s vinyl acetate-ethylene (VAE) technology. These VAE dispersions show improved or similar properties to competing polymer technologies used in bitumen modification.
Tensile adhesion strength test: polymer modification meant that the tensile adhesion strength rose by as much as 60 percent compared to conventional bitumen emulsions.
Adding VINNEVA® to bitumen emulsions can yield one or more of the following benefits:
- Decreased drying times
- Reduced residual tack
- Increased adhesion and wear resistance
- Higher resistance to hydraulic pressure
- Fewer antioxidants required
Main Application Areas:
- Coatings / primers
- Water barriers
