Destination and fields of applications
Anticorrosion protection of steel articles and constructions, used in all atmospheric environments according to ISO 12944-5:2007. The coating is firm in sea and fresh water, in solutions of salts of acids (ðÍ= 6, 0 - 9, 0), in petroleum and petroleum products and can be used in domestic hot and cold drinking water supply systems. Isn’t firm in alcohol and some organic solvents.
The composition quality ZFES is used as:
- an independent coating;
- the primer under coating materials in complex protective systems.
Is recommended for using in coating systems with the aluminium-rich compositions PAES, ALUMOTAN, enamel POLITON-UR , as well as other enamels based on vinyl-epoxy, perchlor-vinyl, copolymer-vinyl chloride, epoxy, epoxy-ester, polyurethane and melamine.
Weld seam quality isn’t deteriorated when welding on one layer coating.

Surface preparation
- Oils, lubricants and other adipose matters as well as moisture and dust are to be removed from the sized metal surface;
- Thoroughly remove cinder and rust to Sa 2,5 according to ISO 8501-1: 1988;
- Remove dust.
Application method
- While constant shuffling, zinc powder is to be gradually added into the container with coupling agent;
- Keep for 30 minutes in order to remove gas (until bulb isolation ends);
- Before using the composition is to be thoroughly shuffled;
- The composition is to be applied in plant and field environment at temperature from - 15 °Ñ to +40 °Ñ and relative air humidity from 30 % to 80 % (not less than 50% is the best).
Every next layer of the composition ZFES is to be applied after drying up of the previous one to «tackiness».
Cure time of the coating ZFES before applying the next layers at temperature 20 °Ñ and relative air humidity 60 % is for:
- coating POLITON-UR – 6 hours;
- coating ALUMOTAN – 6 hours;
- coating PAES – 2 hours.
Cure time of the coating before applying other coating materials is 24 hours.
Cure time of the coating before applying in hostile environment is 7 days.

Packaging and storage
The composition is packed in metal pails (ZFES #1, ZFES #2) and metal cans (ZFES #2). Mass of the set ZFES #1 is 25 kilograms. Mass of the set ZFES #2 is 31, 25 kilograms, mass of the set ZFES #2 in cans is 1,5 kilogram.
Storage conditions: the coupling agent is to be stored in an enclosed warehouse at environment temperature from -40˚C to +40˚C, the zinc powder is to be stored in the manufacturer’s hermetically covered container in an enclosed warehouse in the absence of acids, alkalis and other deleterious substances. The components of the primer are to be stored and transported at temperature from -40˚C to +30˚C in the manufacturer’s hermetically covered container.
Warranty period of the composition is 6 months from the composition due date.
