EPINOX 77

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: 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 St 2. Porous surfaces should be primed with tinted Epinox 77 paint. Coating gets the highest mechanical and chemical resistance by applying directly to sandblast cleaned steel surfaces (cleanliness at least Sa 2½). STEEL SURFACE PREVIOUSLY PRIMED USING SHOPPRIMER: The surface to be treated must be dry and free of contamination. Rust, mechanical, thermal damage or any defects of surface should be cleaned to Sa 2 according to PN-ISO 8501-1 for submerged surfaces, St 3 for external above-water surfaces. For internal surfaces at least St 2. SHOPPRIMED COATING WITHOUT VISIBLE DEFECTS: The surface to be treated must be abrasive blasted (submerged surfaces) or roughened mechanically (external surfaces). EPOXY PAINT FOR PRIMING: The surface to be treated must be dry, salt-, grease- and dust-, corrosion 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 0.019 – 0.025" 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 80 and 200 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. Single coating of dry film thickness 160 – 200 µm (wet film thickness 250 – 320 µm) can be used as a stand-alone protection of internal surfaces, for example for ship’s holds. 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.
