WACKER offers VINNAPAS® polymer dispersions and powders for the formulation of 1K ready-to-use (pasty) systems as well as 1K and 2K cementitious systems.
GENIOSIL® WP alpha-silane-terminated polymers are key to liquid waterproofing membranes.
The portfolio comprises both polymer dispersions and powders; the vinyl acetate-ethylene (VAE) grades comply with the requirements of European ecolabels such as Blue Angel, Emicode EC1 plus, etc.

GENIOSIL® WP Polymers for Liquid Membranes
GENIOSIL® WP silane-terminated polymers are binders for liquid waterproofing membranes that can be applied under unfavorable conditions, dry very fast and show properties comparable to those of polyurethane-based liquid waterproofing coatings – without the addition of solvents or plasticizers. GENIOSIL® WP polymers are based on WACKERs -technology which means they cure without tin catalysts.
Polymer modified waterproofing membranes can bridge cracks caused by movement of the substrate. Liquid waterproofing membranes based on GENIOSIL® WP can be applied easily, even on wet substrates and dry very quickly.
