OLITERM 52 is a silicone anticorrosive primer pigmented with zinc dust. It creates coating well adhered to the substrate, with good mechanical properties and exceptional hardness, resistant to weathering and to high temperature.

For the anticorrosive priming of the steel surfaces exposed to the atmospheric conditions and to temperatures up to 500°C. The paint forms film that withstands permanent heat up to 500°C.

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. In case of amendment after assembly or to correct small defects of layer it is allowed to repaint it with OLITERM 52 but the surface must be cleaned to the degree of cleanliness PSt3 according to ISO 8501-1. In that cases, well adhered paint surface should be intact. The surface prepared for repainting must be free of oil, grease, dust, mill scale and purely adhered rust. Old paint surface and other contamination or impurities, should be cleaned carefully until it gets metallic sheen due to metallic substrate underneath. Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.


Stir the product homogeneous before use. Apply by airless spray or brush. Suitable airless nozzle size 0.013 - 0.017"

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. 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.
