Epoxy primer, MIO pigmented, thixotropic, two component paint.

For priming of steel or cast iron constructions operating in sea, coastal and aggressive environment. For self-protection of steel constructions or elements, in building industry, when high decorative value of coating is not required, water, sewage and petroleum products tanks, external surfaces of tanks and systems used in temperatures up to 160ºC. Semi-gloss, hard and resistant to mechanical factors coating. The coating is resistant to long term exposition to 160ºC temperature. Coating resistant to water, salt and alkali solutions, oil, fuel oil, diesel, motor gasoline and some organic solvents. When exposed to sun radiation, the tint of the coating may change.

Surface preparation

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 at least Sa 2½ for constructions used in immersion and in the aggressive environment; at least St 3 for constructions used in the internal environment. 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. Wait 15 min (at 23ºC) before use. 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: 0.017 - 0.027" 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 70 and 150 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. The compartment must be closed during painting, afterwards must be ventilated as long as the odour is sensible.

Application conditions

During the application and drying period the minimum temperature of the ambient air, the surface and the product shall be above +5°C and the relative air humidity below 85%. 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. Adequate ventilation during application and drying period is recommended.
