Epoxy zincrich primer

  • Corrosion protective
  • 2-component
  • Primer
  • Solvent-borne

TEKNOZINC 3231 is a two component high solid epoxy zinc rich primer.

Primer for Polysiloxane-, Polyurethane- and Epoxy systems.

TEKNOZINC 3231 gives effective corrosion protection and is weather resistant even without Topcoat. It provides long overcoating intervals. The content of zinc in dry film is minimum 90%.

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). 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. The place and time of the preparation are to be chosen so that the prepared surface will not get dirty or damp before the subsequent treatment.
