DescriptionTwo component polyurethane primer-enamel, hardened by aliphatic polyisocyanate.
Scope and specifics of application
Polytex BS primer enamel is used as a self-priming anti-corrosion coating with an accelerated open time and a fast mounting strength. It is available with a different degree of gloss: from deep-matt to high-gloss, has a wide choice of color solutions. It does not require pre-priming. Thick-layer application is possible.
It is used to paint and provide long-term anti-corrosion protection of internal and external surfaces of various vehicles: agricultural machinery, construction equipment, public transport (buses, trolleybuses, trams, etc.), railway transport, as well as other metal structures.
Primer-enamel has increased strength, hardness, abrasion resistance and accelerated open time. It is successfully used in moderate, cold and marine climates, providing long-term protection against corrosion.
Information on the material resistance to various media is available on request.Main applications: mechanical engineering.
Instruction for use
Metal surface should be abrasive blasted to grade 1 or 2 to GOST 9.402 (Sa 2^(1/2) 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.
Two component polyurethane primer-enamel Polytex BS is applied on prepared surface, with ambient temperature from +50С to +300С and air humidity no more than 80%. Basis temperature higher than dew point no less than 3°C.
The process of applying
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.
