High performance, clear polyurethane coating

Decothane Clearglaze is a clear aliphatic, polycarbonate polyurethane coating which forms an effective barrier to water penetration and the ingress of atmospheric chemicals.

  • Easy to use.
  • High solids formulation.
  • Moisture triggered curing – does not foam when excess moisture is present.
  • 'Wet look' finish when applied to porous surfaces.
  • Does not discolour with age or prolonged UV exposure.
Usage
