EPIRUST
Epoxy primer
- Corrosion protective
- Wear resistant
- 2-component
- Solvent-borne
- Primer
Modified epoxy primer, cured with polyamide, two component.
For priming of steel, aluminium or galvanised constructions operating in sea, urban and industrial environment. For priming of steel, cast iron and aluminium constructions operating in immersion. Flexible coating, with good adhesion to surfaces and resistant to mechanical factors. The coating resistant to weathering, water, salt and alkali solutions, oil, fuel oil, diesel, motor gasoline.
Technical data sheet
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.
STEEL SURFACE: cleaned to the degree of cleanliness according to ISO 8501-1: at least Sa 2½ for constructions operating in immersion and in aggressive environment, when long term protection is needed; at least Sa 2 for constructions used in atmospheric conditions; well attached tarnish rust is acceptable; St 3 for constructions used in atmospheric conditions. Dry, salt-, grease-, dust- and poor-attached-rust-free surface.
NO STABILIZED HOT DIP GALVANIZED STEEL SURFACES AND DRY ALUMINUM SURFACES: should be tarnish with non-metallic abrasive. All contamination e.g. oil, grease, fluxing agent, etc. should be removed. Galvanized surface should be contaminant-free.
STABILIZED HOT DIP GALVANIZED STEEL SURFACES: should be zinc corrosion products free (white rust free) and any contaminant-free. For cleaning hot water, water under pressure, steam, abrasives or manual mechanic tool cleaning can be used. The surface for painting should be dry, dust-, grease- and salt-free.
THERMALLY SPRAYED GALVANIZED AND ALUMINUM SURFACES: should be dry and primed immediately with thin layer of diluted EPIRUST 2002, EPIRUST or shop primer, before any condensation occurs. The surface for painting should be dry, dust-, grease- and salt-free.
Application
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. Mix thoroughly components and wait 15 minutes (at 23°C) before use.
Apply by airless spray or brush. When painting on wet or corroded surfaces it is recommended to apply first layer by brush.
Airless spray parameter:
Nozzle size 0.015 - 0.019".
Nozzle pressure 10-15 MPa.
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 35 and 60 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.
Application conditions
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 85%. Good ventilation should be provided. 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.
Storage
The storage stability is shown on the label.
Store in a cool place and in tightly closed containers.
Mix thoroughly components and wait 15 minutes (at 23°C) before use.
