      Description

      Two component polyurethane primer, hardened by aliphatic polyisocyanate.

      Scope and specifics of application

      Polytex BS primer enhances the protective anti-corrosion properties of the complex coating. It is intended to prime metal structures in the industrial atmosphere of moderate-cold and cold climates exposed to vibration stress.

      It is used to prime railway and urban transport, construction metal structures, oil and gas pipelines, tanks, oil storage facilities, bridges, hydraulic facilities, power transmission towers, cell towers, devices and equipment, as well as other metal surfaces with high requirements for hardness, strength, abrasion resistance, moisture resistance. It is characterized by good sanding, bending strength, improved adhesion, and accelerated open time.

      As part of a complex coating, it is successfully used in moderate and cold climates, while providing long-term protection against corrosion.

      Information on the material resistance to various media is available on request.

      Main fields of application: oil and gas industry, transport construction, power engineering, tank equipment, mechanical engineering, chemical industry.

      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 ISO8501-1:2007). 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

      Ambient temperature from  +5°С  to +30°C.
      Relative air humidity  no more 80%

      The process of applying

      Blending

      Polyurethane primer 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.
