TEKNODUR MIOX 9202-01
Polyurethan top coat
- Corrosion protective
- 2-component
- Solvent-borne
- Topcoat
TEKNODUR MIOX 9202-01 is a iron mica-containing two-pack polyurethane topcoat. The hardener is an aliphatic isocyanate resin.
TEKNODUR MIOX 9202-01 is a versatile topcoat for smooth and blasted steel SA 2 ½, as well as for zinc and aluminium surfaces or for suitable primers, e.g. TEKNODUR PRIMER 3420.
TEKNODUR MIOX 9202-01 has an excellent corrosion protection, good mechanical stability and also a good weather resistance.
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.
ZINC SURFACES: Hot-dip-galvanized steel structures that are exposed to
atmospheric corrosion can be painted if the surfaces are sweep blasted (SaS) till
matt all over. Suitable blasting agents are, e.g. aluminium oxide and natural sand. It
is not recommended to paint galvanized objects that are subjected to immersion
strain. It is recommended that new zinc-coated thin-plate structures are treated with
sweep blast-cleaning (SaS). Surfaces that have been weathered to matt can be
treated also with PELTIPESU Cleaning Agent.
The place and the time of the preparation are to be chosen so that the prepared
surface will not get dirty or damp before subsequent treatment.
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 over coating time are to be roughened as well.
