Description
Polyurethane two-component primer-Polytex mio enamel.Scope and specifics of application
Polytex MIO enamel primer contains phosphate corrosion inhibitors and iron oxide mica, which form the strongest barrier effect of protecting the metal from the corrosive environment impact during the entire service life. It significantly increases the operation of the paint coating. Suitable for repair work.
It is used to paint and provide long-term anti-corrosion protection of concrete, reinforced concrete and metal structures operated in the conditions of industrial atmosphere of moderate, cold and marine climate, including transport infrastructure objects: railway bridges, road bridges, tunnels, ground parts of piles, supports of overpasses, pipelines, road fences, navigation and vehicle control objects, underwater parts of hydraulic facilities and other metal structures and equipment exposed to severe atmospheric corrosion.
The iron mica contained in the composition forms a tile overlap in the paint layer, i.e. it reinforces the coating, providing effective barrier protection of the metal from atmospheric impact, industrial air, moisture and water.
Information on the material resistance to various media is available on request.
Main applications: transport construction, tank equipment, oil and gas industry, power engineering, railway transport facilities.Instruction for use
Metal surface should be abrasive blasted to grade 1 or 2 to GOST 9.402 (Sa 2,5 or Sa 2 to ISO 8501-1:2007). Clean surface must be free from dust and grease.
If the quality of surface preparation decreases, the service life and its operating performance may change.
Conditions
Relative air humidity no more 80%.
The process of applying
|
Blending |
Polyurethane primer-enamel consists of two components: component А - basis, component B - hardener. Before use, pre-mix component A with a low-speed drill with mixing nozzle, then mix with component B in stoichiometric ratio in the delivery form. Mix the resulting material thoroughly until smooth. After the hardener is added into the semi-finished product, the material should be allowed to stand for at least 5-10 minutes. |
