Vinyl primer

  • Corrosion protective
  • Heat resistant
  • 1-component
  • Solvent-borne
  • Primer

UNIWIN W is a 1-pack, vinyl primer that contains active anticorrosive pigments.

The paint is used as anticorrosive primer. For steel constructions exploited in urban and industry atmosphere. UNIWIN W creates coating, with good adhesion to steel surface, flexible and mechanically resistant.

Technical data sheet

Surface preparation

Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Before cleaning of surface, it is recommended to wash it with water with addition of OLICLEAN 123 and then rinse with fresh water. STEEL SURFACES: Remove mill scale and rust by blast-cleaning to preparation grade Sa 2½ or by treating mechanically to preparation grade St 3 (ISO 8501-1). The preparation grade is chosen by the object and current corrosivity category. Roughening the surface of thin-plate improves the adhesion of the paint to the substrate. 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. Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.


Stir thoroughly before use. Apply by airless spray or brush. Airless spray parameter: Nozzle size 0.013 - 0.019". Nozzle pressure 10-15 MPa. Depending on application and type of construction, other thickness of a single layer can be assumed instead of recommended. Typical dry film thickness range using airless spray is from 20 to 80 microns. Changing the thickness of the coating changes the theoretical consumption, thickness, weight of dry coating, drying time, time of recoating and finishing work.

Application conditions

The surface to be treated must be dry. During the application and drying period the temperature of the ambient air shall be above -10°C (frost- and ice-free surface) and at least 3°C higher than dew point of the ambient air. Adequate ventilation during application and drying period is recommended.


The storage stability is shown on the label. Must be stored tightly closed and kept cool and dry.
