Polyurethane matting varnish PRASPAN® PU-T300

Description

Praspan® PU-T300 is a two-component thin-layer matting polyurethane varnish designed for decorative concrete substrates.

This material is used as a final decorative and protective coating for industrial floors such as polymer self-leveling floors, concrete-based floors, and decorative floors for commercial areas (terrazzo/mosaic floors): Linolit® Ansaf, Linolit® Design Terrazzo, Linolit® MicroTerrazzo and others. It is intended for areas subjected to light and medium abrasive loads, as well as light, medium and moderately heavy static and dynamic loads.

Key properties:

  • uniform, smooth matte floor surface;
  • high adhesion to the substrate;
  • provides UV resistance to the decorative coating;
  • wear resistance and durability;
  • easy to maintain;
  • aesthetic appearance.
