TEKNOCRYL 2K 2540-05
NISO - Acrylic top coat
- Topcoat
TEKNOCRYL 2K 2540-05 is a two-pack acrylic paint where the hardener used is an isocyanate-free special hardener.
Used in coating systems as a top coat on epoxy paints, e.g. TEKNOPLAST PRIMER 7. Used in coating system K77 which corresponds with coating system 1 in standard NORSOK M-501 rev. 5:2004, Annex A. The coating system is tested and approved according to ISO 20340 test requirements. TEKNOCRYL 2K 2540-05 forms a semigloss surface that will withstand well abrasion and weather.
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:
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.
Application
MIXING OF THE COMPONENTS: Take into consideration the pot life of the mixture when estimating the amount to be mixed at a time. Before application the base and hardener are mixed in right proportion. Stir thoroughly down to the bottom of the vessel. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties.
Stir thoroughly before use. Before use clean the spray gun and paint vessels with a thinner suitable for the paint.
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%. Additionally, the temperature of the surface to be treated and the product must be at least +3°C above the dew point of the ambient air.
Storage
The storage stability is shown on the label. Must be stored tightly closed and kept cool.
Suitable airless nozzle size 0.011 - 0.013".
