TEKNODUR TEXTURE 9203
Polyurethane coat
- Corrosion protective
- 2-component
- Solvent-borne
- Topcoat
TEKNODUR TEXTURE 9203 is a two-pack polyurethane topcoat. The hardener is an aliphatic isocyanate.
TEKNODUR 9201-09 is a high quality and versatile topcoat for smooth and blasted steel surfaces.
TEKNODUR TEXTURE 9203 is a matt two-pack polyurethancoat with very good adhesion to even or blasted steel. It combines an excellent protection from corrosion and a high surface quality with Soft feel-effect and good weather stability.
Technical data sheet
Surface preparation
Remove from the surface any contaminants that might be detrimental to surface
preparation and coating. Remove also water-soluble salts by using appropriate
methods. The surface should be prepared as follows:
STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation
grade Sa 2½ (standard ISO 8501-1). Roughening the surface of thin-plate
improves the adhesion of the paint to the substrate.
OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Any impurities
that might be detrimental to the application of paint (e.g. grease and salts) are to
be removed. The surface must be dry and clean. Old, painted surfaces that have
exceeded the maximum overcoating time are to be roughened as well. Damaged
parts are prepared in accordance with the requirements of the substrate and the
maintenance coating
