TEKNOZINC ESI 3180

Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. 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: Remove mill scale and rust by blast cleaning to preparation grade Sa 2½ (standard ISO 8501-1). The surface to be treated must be dry, clean, salt-, grease- and dust-free. 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.

Take into consideration the pot life of the mixture when estimating the amount to be mixed at a time. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties. TEKNOZINC ESI 3180 is supplied in two components consisting of a canister containing a pigmented binder and a drum containing a bag with zinc dust. Before mixing, remove the bag with the zinc dust. The canister should be shaken to obtain a homogeneous content. Make sure that there is no sediment on the bottom. Then pour the content of the canister into the empty drum and add slowly the zinc dust to the binder. During adding the zinc dust to the binder use a mechanically agitator to obtain a homogeneous consistency. Before application, the product should be filtered through a sieve with a mesh side dimension of min. 200 µm. Apply by airless spray equipped with a mixer. The paint must be frequently stirred in the course of work in order to avoid sedimentation of the zinc dust. Airless spray application recommendation: nozzle size 0,015 - 0,023” pressure 15 - 20 MPa. While drawing up the painting specification, depending on the destination and type of a construction, it is possible to assume the thickness of a single coat other than the one recommended for application in the manual. During the airless spraying, the typical range of coat thicknesses is from 50 to 80 µm.

During the application and drying period the temperature of the surface shall be above -5°C (frost- and ice-free surface), at least 3°C above the dew point of the ambient air and the relative air humidity 50 – 95%. Adequate ventilation during application and drying period should be provided. At low air humidity, it is possible to speed up the process of curing the coat by spraying the painted surface with water. The spraying may be started after 1 hour (at 23°C) from application of the TEKNOZINC ESI 3180 paint.

The storage stability is shown on the label. Store in a cool place and in tightly closed containers.
