TEKNOSYNT PRIMER 3 is a thixotropic, quick-drying paint that is thinned with white spirit and contains active anticorrosive pigments.
Used in field and station painting of structural steel exposed to urban, marine or industrial climate. Also suitable to be applied by brush on wire-brushed surfaces and for product coating, e.g. painting of transport equipment.
Technical data sheet
Surface preparation
Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods. The surfaces are prepared according to the different materials as follows:
STEEL SURFACES: Remove mill scale and rust by blast-cleaning to preparation grade Sa 2 or wire-brushing to preparation grade St 2 (red colour) (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 removed. The surfaces 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.
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.
Prefabrication primer: KORRO PVB, KORRO E Epoxy and KORRO SS Zinc Silicate Prefabrication primers can be used, when required.
Application
Stir thoroughly before use. Suitable airless nozzle size 0.015 - 0.018".
Application conditions
The surface to be treated must be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +5°C and the relative air humidity below 80%.
Storage
The storage stability is shown on the label. Store in a cool place and in tightly closed containers.
