Description
Zinc-filled single-packing material based on high-molecular synthetic polymer.
Scope and specifics of application
Primer Policing designed for cathodic corrosion protection products, construction and structures made of ferrous metals, operated in atmospheric conditions, in the conditions of water-saline mist, in the environment of vapours and aerosols of petroleum products.
The material can be used as an independent coating, and as a primer layer.
It is possible to use as an alternative to hot-dip galvanizing.
Due to the combination of cathodic and barrier protection mechanisms, the primer has a special resistance to sea, fresh and polluted water, high humidity, medium and highly aggressive industrial atmosphere. The coating is resistant to spills of sea and fresh water, aqueous solutions of salts, oil and petroleum products.
It is successfully used for the protection of steel structures, bridges and hydraulic structures, ports and ship structures, overpasses and platforms, as well as in the construction of railway and, in particular, sea and river transport. Suitable for painting horizontal and vertical surfaces of pumping and capacitive equipment of mineral oil storage tanks, salt solutions, alkalis, oil products, tanks, storage facilities, pipes and pipelines, oil and gas pipelines.
Information on the resistance of the material to different media is available on request.
Surface preparation
The metal surface to clean by abrasive blast method to degree 1 or 2 according to GOST standard 9.402 (Sa 2^(1/2) or Sa 2 according to ISO 8501-1:2007) with a roughening, the recommended surface profile is Rz =30-50µm. Dust and degrease the cleaned surface.
Application on a smooth surface without roughening is not allowed!
Application conditions
Ambient temperature from +5°C to + 35°C.
Humidity - no more than 80%.
The process of applying
| Preparation |
The primer is ready for use. Before applying the composition must be thoroughly mixed with a construction mixer until smooth |
| Airless spraying |
Dilution: up to 5% Nozzle diameter: 0.015-0.021" Initial pressure: 10-20 MPa (100-200 bar) |
| Air spray |
Working viscosity: 40-60 sec Dilution: 10-30% Nozzle diameter: 1.8-2.2 mm Initial pressure: 0.2-0.4 MPa (3-40 bar) |
|
Interlayer exposure at 20°C |
Not less than 2 h for ALURON AL
At least 24 hours for other coating layers |
| Brush, roller |
It is recommended to use only for small areas or hard-to-reach areas. When applying the brush, dilute the primer depending on the condition of painting |
|
Diluent |
Prescription thinner RP-1K |
| Purifier | Prescription thinner RP-1K, R-4 |
| Work stoppage | The product must not remain in hoses, gun or other spraying equipment |
| Equipment washing |
Rinse the equipment immediately after use. The frequency of flushing depends on the amount of material sprayed, the temperature and the time elapsed after the shutdown, including any delays
