Shop primer ZFES-MO -- two-package anticorrosion complex primer:
Component A (base) -- paste of fine zinc powder;
Component B (binder) -- ethyl-silicate solution.
Mass ratio of components A:B is 5:1 correspondingly. Due to high
zinc content shop primer ZFES is anodic towards steel and provides
its cathode protection. Shop primer ZFES -MO is used as an inter-operation
protection means during storage and transportation of cast iron
and steel assembly units, intended for metal structures assemblage.
General characteristics of the shop primer:
dries fast, so is fit for conveyer lines;
doesn't need removal after the inter-operation storage is over,
as it is compatible with all types of primers and top materials;
has a high abrasive resistance; Welding upon 1-layer coating of
the shop primer ZFES-MO doesn't worsen the quality of the welding
seam.
Shop primer ZFES is intended for anticorrosion protection
of steel constructions:
in atmosphere conditions of all macro-climatic zones and categories
of location. 1-layer coating provides anticorrosion protection up
to 9 months depending on the storage conditions;
in fresh water, in petroleum and clear petroleum products as a
primer in complex protective systems.

Application method Shop primer ZFES-MO can be applied in
shop and field conditions at temperature from -15 up to +400C
and relative humidity from 30 to 80% (optimal - not less than 50%).
Temperature of painted surface should be not less than 3оС higher
than dew point.
Surface preparation:
degrease the surface of the metal;
blast-cleaning of the metal surface and removal of oxides (rust
and scale) up to grade Sa 2 as per ISO 8501-1:1988.
Shop primer ZFES-MO is prepared as follows:
stir component A (base) thoroughly;
component B (binder) should be slowly poured into the pail with
component A at constant stirring, than the mixture should be kept
intact for 30 minutes, stir again and filter if necessary.
Methods of application: pneumatic and airless spraying.
Natural curing. Time before application of top materials is minimum
24 hours, maximum - 9 months (if there are no surface defects,
the interval can be even longer). The equipment should be thoroughly
washed by solvents. It is not recommended to use xylol, toluene,
white-spirit and also their mixtures. It is necessary to observe
corresponding branch norms and regulations at work with shop primer
ZFES-MO. The coating is not toxic and can be applied within service
premises and living quarters. Shop primer ZFES-MO is fire-proof
and relates to materials not spreading fire on the surface.
