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

This highly elastic cold-curing polymer-hybrid composition with an elongation at break of 700 % works as a membrane under rigid coatings in freezer rooms and entry zones. It is also used as a chemical-resistant sealant, an adhesive, a waterproofing membrane and protection for metal and concrete against aggressive effluents. Tear resistance is 43 N/mm and heat resistance up to +140 °C. To control application, the manufacturer recommends contrasting colours.
