Applications & Uses
- Applications
- Application Area
- Uses
Used to protect FBE mainline coatings for directional drilling, bores, river crossings and other rough terrain applications. Protal ARO can be used to provide additional protection to the coating on bends, fittings and fabrication when severe handling or rough terrain persist. The coating should not be applied direct to steel.
- Application
Brush: Prepare FBE coating with a light sweep blast to remove gloss and roughen surface (approx. 1 mil). After sweep blast wipe entire surface with MEK or approved solvent to remove all dust and other surface contamination. Add the hardener to base and mix at a slow speed until a constant color is achieved making sure all sides of container are scraped. Pour mixed material onto surface and brush, trowel or roll to required mil thickness. A wet-film thickness gage shall be used to measure mil thickness. If surface temperature falls below 50°F (10°C), surface should be preheated to achieve faster cure. Preheat may be achieved with a propane torch or induction coil. Resin and hardener component shall be kept warm, at a minimum of 60°F (15°C), to mix easily.
Spray: Prepare FBE coating with a light sweep blast to remove gloss and roughen surface (approx. 1 mil). After sweep blast wipe entire surface with MEK or approved solvent to remove all dust and other surface contamination. The equipment should be a plural component airless spray unit with a proportioning pump capable of a volume mixing ratio of 3:1. Standard ancillary equipment should include minimum 10 gallon hoppers, 2 ea. static mixers, 25 ft. (7.6 m) max x 1/4" (6.4 mm) whip hose, and mastic gun with a 21 to 35 thou tip. (Applicator should consult with Denso regarding recommended equipment). Part A should be heated to 150°F -160°F (65°C - 71°C) and Part B heated to 150°F -160°F (65°C - 71°C). Hose bundle shall be set at 135°F - 145°F (57°C - 63°C). A wet-on-wet spray technique should be used to achieve a minimum thickness of 30 mils (750 microns). The coating thickness should be measured using a wet-film thickness gage.
For complete application instructions, please refer to the Protal ARO Brush or Spray Application Specifications.
- Cleaning
Clean equipment with MEK or equivalent solvent cleaner.
