FEIDOPUR PRIMER ZG23-G3
2C-PU primer
- Corrosion protective
- Wear resistant
- 2-component
- Filler
- Primer
FEIDOPUR PRIMER ZG23-G3 is a high-quality, two-component priming filler based on special polyurethane resin. It provides a satin finish and excellent application properties. ZG23-G3 is sandable, temporarily non-chalking and therefore suitable for outdoor storage.
With active pigmentation, it provides excellent corrosion protection for steel components exposed to demanding industrial conditions. Common applications include commercial vehicle construction, as well as the construction of containers, plants, engines and machinery.
Surface preparation
Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods.
STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation grade Sa 2½ (standard ISO 8501-1). Residues that may weaken adhesion, such as oil, grease, dust must always be carefully removed before application.
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.
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.
Stir thoroughly before use.
Brush or roller can be used for touching up and painting small areas.
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 below +35°C and the relative air humidity below 85%. The temperature of the surface to be treated must be at least +3°C above the dew point of the ambient air. During application good ventilation is recommended.
Storage
Storage stability is 1 year in unopened package. Store in a cool place and in tightly closed containers. Most suitable storage temperature is +5°C - +25°C. The hardener reacts with air humidity and therefore the can is to be kept carefully closed. Protect from heat and freeze!

| Safety markings | See safety data sheet. The hardener of the product and the ready mixture contain isocyanates. In poorly ventilated areas and especially when using spray application we recommend the use of a fresh air mask. In short or temporary work, a mask with combined filter A2-P2 can be used. In this case eyes and face are to be protected. |
