Primers HS-068

Purpose (XC-068)  Designed for protection in complex multi-layer coating of equipment and metal structures from exposure to mineral acids and alkalis at temperatures up to 60 ° C, as well as under XB, XC enamels.

 

Application

Thoroughly clean dust and any other dirt or rust and degrease. Before applying the primer, mix thoroughly and dilute with solvent R-4 to a working viscosity of 12-14 seconds. viscometer type VZ-246 with a nozzle diameter of 4 mm at a temperature of (20 ± 2) ° C. The primer is applied by pneumatic spraying, brush, roller. An expense on 2 layers – 310 g / m ?.
