TEKNODUR AQUA 3393-23

Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. The surfaces are prepared according to the different materials as follows: 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.

MIXING OF THE COMPONENTS: Slowly add the hardener in one go during mechanically stirring. The stirring time is at least 5 min. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties. Dosage may also be done through a 2-K mixing system. THE READY MIXTURE MUST BE USED WITHIN THE POT LIFE, MIXTURES OLDER THAN THIS ARE UNFIT FOR USE.

The surface to be treated must be dry. During the application and drying period, the temperature of the ambient air, the surface and the paint shall be above +18°C and the relative air humidity above 50% and below 70%. Surface temperature, film thickness, drying temperature and ventilation affect the drying of the paint.

The storage stability is shown on the label. Store indoors in a cool and dry place and in a tightly closed can. The hardener reacts with air humidity and therefore the opened can is to be kept carefully closed, and it is recommended to be used within 14 d of opening.

Slowly add the hardener in one go during mechanically stirring.
