375 μm (15 mil) WFT yields 300 μm (12 mil) DFT

  • 14 liter kit covers 36.75 m2 (395.57 ft2)
  • For gaseous and condensing gas applications ARC S7 AR is recommended to be applied as a 2-coat system at 375 - 500 μm (15 - 20 mil) wft1 p​er coat. The recommended total dft2 is 650 -850 μm (25 - 30 mil)​​
  • For immersion applications it is recommended to use ARC S7 as a base coat, followed by ARC S7 AR as a top coat 
  • Note: Components are pre-measured​ and pre-weighed.
    Each kit includes mixing and application instructions.
  • 1 wft = wet film thickness
    2 dft = dry film thickness​
    Maintain transport temperature below 24°C (75°F)
