Technical Info

Usage

PREPARATION

Two prior coats of TU0022/00 PU Basecoat. Denib when fully dry. For best results, we suggest preparing the surface using 240-320 grit stearate abrasives as they provide a higher efficiency than conventional. Ensure the surface is completely clean of dust and debris before coating.

APPLICATION

With good drying conditions and air circulation (20°C), a good build can be achieved with one coat of 150 g/m². Lower temperatures and higher relative humidity can lead to longer drying times, but it is possible to speed up drying using heated ovens.

AFTER CARE

Due to the high chemical resistance of Polyurethane Topcoats, the packaging used does not usually cause problems. We recommend high-density polythene. PVC or Pluriball are not suitable.
