QTP® 2161 — colourless matt water-based polyurethane varnish
Two-component water-based polyurethane varnish for a matt finish coat on polymer floors.

Application on damp surfaces is the key property of this water-reducible epoxy primer. It is used neat or with quartz, for impregnating fresh and old concrete and screeds, and for protecting fresh concrete during equipment installation before the polymer coating is applied. The solids content is 54 % and compressive strength 85 MPa. Continuous heat resistance is up to +70 °C.
