- Uses
Spray or hand applied to pipelines operating at elevated temperatures. Used on girth welds, pipe, fittings, valves and fabrication.
- Application
Brush: Prepare surfaces by grit blasting to a clean near white fi nish, SSPC-SP 10/ NACE No. 2. Appropriate angular grit shall be used to achieve a 2.5 to 5 mil (0.063 - 0.125 mm) anchor profi le. Initially stir the base and hardener. 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 fi lm 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. Product can be applied to surfaces ranging from 40°F (4°C) to 220°F (105°C) at a minimum of 30 mils. Immediately pour mixed material onto surface and brush, trowel or roll to required mil thickness. A wet fi lm thickness gage should be used to measure mil thickness.
Spray: Prepare surfaces by grit blasting to a clean near-white finish, SSPC-SP 10 / NACE No. 2. 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 (37.85 liter) hoppers, 2 ea. static mixers, 25 ft. (7.3 m) max x 1/4" (0.64 cm) whip hose, and mastic gun with a 19 to 27 thou tip. (Applicator should consult with Denso regarding recommended equipment). Part A should be heated to 130°F -140°F (54°C - 60°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 25 mils (635 microns). The coating thickness should be measured using a wet-film thickness gage. The equipment settings are only guidelines and may vary based on equipment.
