Anticorrosion composition ALUMOTAN
|
Description
The composition is suspension consisting of aluminum powder and functional additives in polyurethane varnish and mixture of organic solvents. One-package composition, cured by air-moisture.
| |
Destination and fields of applications
Is used as
- a top coat upon coating ZINOTAN, ZINEP, ZFES for increase of protective and decorative behavior;
- an independent decorative coating for steel surfaces in atmosphere conditions.
The coating is weatherproof in all macroclimatic zones conditions and fast in sea and fresh water, in water solutions of salts, acids and alkali, in petroleum and petroleum products.
Certification, testing
The sanitary-and-epidemiologic finding ¹ 66.01.10.231.Ï.001370.05.04 dated 12.05.2004. Certificate of conformance ¹ ÐÎÑÑ RU.KK01.H00068.
Recommendations are given by the trust «Gidromontazh», processing directives for painting operated railway bridges given by Communication Lines Department.
Findings are given by Transportation Problems and Energy Resources Institute, Bashkir Research Institute for Petroleum, All-Russian Research Institute for Rail Transportation.

Reccomended condition of the painted surface
The undercoat should be cleaned of dirt, degreased and free from dust.
When using the composition ALUMOTAN as an independent decorative coating, it is necessary:
- oils, lubricants and other adipose matters as well as moisture and dust are to be removed from the metal surface;
- thoroughly remove mill scale, rust and old paints traces by means of jet- rubbing method to Sa 2,5 rate (S 2 is allowed) according to ISO 8501-1. Mechanical cleaning to St 2 rate (St 3 is allowed) is permitted, according to ISO 8501-1;
- 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;
- When intervals in working, air junction is to be restrained (the pail with the composition is to be covered);
- The composition can be applied in plant and field environment at temperature from -15 °Ñ to +40 °Ñ and relative air humidity form 30 % to 98 %.
When air humidity increases, drying time of the coating decreases. Applying of drying accelerator for polyurethane paint-and-lacquer materials for decreasing drying time (in 1,5-2,5 times) in plant environment at relative air humidity less than 30 % is recommended when adjusted with the technologists of Fine Metal Powders Co.
Cure time of the undercoat before applying the composition ALUMOTAN at temperature (20+2) °Ñ and relative air humidity 65 % is for:
- ñoating ZINOTAN – not less than 4 hours;
- ñoating ZINEP – not less than 12 hours;
- ñoating ZVES – not less than 6 hours.
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 is natural.
