QTP® 4630 — rigid-elastic coating for ramps and entrances
Epoxy-polyurethane coating for areas of heavy vehicle traffic, ramps and entrances, performing from −60 to +60 °C.

Work at sub-zero temperatures is the main distinguishing feature of this one-component polyurethane paint: the substrate and air may be from −20 °C to +30 °C. The solvent-free paint cures with atmospheric moisture and forms a thin-film grey gloss protective coating on concrete and mineral substrates. For a rough surface, quartz sand is broadcast between coats. The paint yellows under ultraviolet light; foot traffic is possible after just 4 h at +20 °C.
