TEKNODUR 9201-09
Polyurethan top coat
- Corrosion protective
- Special adhesion
- 2-component
- Solvent-borne
- Topcoat
TEKNODUR 9201-09 is a two-pack polyurethane topcoat. The hardener is an aliphatic isocyanate resin.
TEKNODUR 9201-09 is a high quality and versatile topcoat for smooth and blasted steel surfaces.
TEKNODUR 9201-09 is a two-pack polyurethane topcoat with very good adhesion on steel surfaces or a suitable primer such as: 49470 TEKNOLAC PRIMER 2275. It has good corrosion resistance, high finish quality and also a good weather resistance.
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 roughend as well. Damaged
parts are prepared in accordance with the requirements of the substrate and the
maintenance coating.
Suitable Primer are for e.g.
49470 TEKNOLAC PRIMER 2275
