EPITAN 92

Before cleaning of surface, it is recommended to wash it with water with addition of OLICLEAN 123 and then rinse with fresh water. The surfaces are prepared according to the different materials as follows: STEEL SURFACES: The surface to be treated must be dry, salt-, grease- and dust-free, cleaned to the degree of cleanliness according to ISO 8501-1: Sa 2½ for submerged areas or at least St 3 for external surfaces. For internal surfaces at least Sa 2½. Porous surfaces should be primed with thinned EPITAN 92 paint. Coating gets the highest mechanical and chemical resistance by applying directly to sandblast cleaned steel surfaces (cleanliness at least Sa 2½). COATING OF EPOXY PAINT: The surface to be treated must be without any rust, dry, salt-, grease- and dust-free. Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.

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. Mixing by machine is recommended, for example a slow-rotating hand-drill equipped with a mixer. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties. Apply by airless spray or brush. When using a brush it may be necessary to apply several layers to achieve recommended coating thickness. Airless spray parameter: Nozzle size 0.48 - 0.63 mm Nozzle pressure 20 - 25 MPa When preparing painting specification, depending on subject and type of construction, different dry film thickness than recommended can be assumed. During airless spray application typical dry film thickness range is between 150 and 250 µm. Different dry film thickness than recommended causes change in theoretical spreading rate, wet film thickness, weight of dry film thickness, drying time, overcoating time and ready for handling time. In high corrosive environment it is recommended to prepare surface as best as possible and to apply successive layers of paint before full curing of previous layers to achieve best protection.

During the application and drying period the temperature of the ambient air shall be above -10°C, of the paint should be over +15°C and the relative air humidity below 95%. The minimum temperature of the surface shall be above -5°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. Store in a cool place and in tightly closed containers.
