Two component polyurethane primer Polytex SQ.
Scope and specifics of application
Provides long-term protection against corrosion at temperature extremes.
It is used for priming of vehicles surfaces: agricultural machinery, construction equipment, railway transport (all types of rolling stock), public transport (buses, trolleybuses, trams, etc.), machine tools as well as diverse transport metal structures and metal products exposed to increased mechanical stress.
Polytex SQ primer has good adhesion, bending strength, abrasion resistance as well as fast drying time.
Information on the resistance to different media is available on request.
Fields of application: power engineering, mechanical engineering, railway transport facilities, transport construction.
Clean metal surface with blast method to St 1 or 2 according to GOST 9.402 (Sa 2^(1/2) или Sa 2 по ИСО 8501-1:2007), surface preparation level St2 according to ISO 8501-1:2007 is possible. Clean of grease, oil and dirt.
If the surface preparation quality decreases, the service life and operation may change.
Base dew point temperature must be no less than 30С.
Environment temperature from +50С to +300С.
Relative air humidity no more than 80%.
The process of applying
Polyurethane primer consists of two components: component A-base, component B-hardener. Component A is pre-mixed before use with a low-speed drill with a stirring nozzle and then mixed with component B in a stoichiometric ratio in the bucket. The resulting material is thoroughly mixed until smooth. After the hardener is added to the semi-finished product, the material must be tolerated no less than 5-10 min
