Anticorrosion zinc-rich composition ZINOTAN
|
Description
One-package composition based on polyurethane varnish and fine zinc powder, cured by air moisture.
| |
Destination and fields of applications
Anticorrosion protection of steel and reinforced-concrete building constructions, used in all atmospheric environments according to ISO 12944-5:2007, including in very polluted industrial zones; in sea and fresh water, in solutions of salts of acids, in petroleum and petroleum products.
Is used as the priming layer under coating materials in complex protective systems or as an independent coating in atmospheric environments.
Is recommended for using in coating systems with the materials of Fine Metal Powders manufacture: FERROTAN, ALUMOTAN, POLITON-UR (UF), POLITON-UR, PULAK, as well as other materials based on polyurethane and vinyl.
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 mill scale, rust and old paints traces to Sa 2, 5 or Sa 2 according to ISO 8501-1: 1988. Mechanical cleaning to St 3 or St 2 according to ISO 8501-1:1988 is allowed;
- Remove dust.
Application method
- The composition is to be thoroughly shuffled up to homogeneous state before using;
- If necessary it is to be diluted by solvent to operating viscosity before applying;
- The composition can be applied in plant and field environment at temperature from -15 °Ñ to +40 °Ñ and relative air humidity from 30% up to 98 %.
When applying multiple coatings, every next layer is to be applied after drying up of the previous one to «tackiness» (when after light finger pressing of the coating, there are no print and sense of adhesiveness on the coating).
Drying up of the coating ZINOTAN before applying the coatings FERROTAN, POLITON-UR, ALUMOTAN, PULAK at temperature (20±2) °Ñ and relative humidity 65 % is not less than 4 hours.
When relative air humidity is less than 30 %, applying the composition with drying accelerator for polyurethane paint-and-lacquer materials for decreasing drying time (in 4-6 times) is recommended when adjusted with the technologists of Fine Metal Powders Co.
Cure time of the coating before applying in hostile environments is 7 days.
