Protal 7900HT is a VOC free, 100% solids epoxy coating for pipelines operating at higher temperatures. It is a high build liquid coating that can be hand or spray applied in one coat in the field or shop. It cures fast to allow quick backfill when applied to hot pipe.
Spray or hand applied to pipelines operating at temperatures up to 250°F (121°C). Used on girth welds, pipe, fittings, valves and fabrication.
· High build (up to 40 mils in one coat)
· Can be hand or spray applied
· Excellent adhesion
· Intermittent service temperature up to 302°F (150°C)
· Very low permeability
· High abrasion resistance
· Safe and environmentally responsible
· Does not shield cathodic protection
Brush: Prepare surfaces by grit blasting to a clean near white finish, SSC-SP 10/ NACE No. 2. Appropriate angular grit shall be used to achieve a 2.5 to 5 mil anchor profile. 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 gauge 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 gauge should be used to measure mil thickness.
Spray: Prepare surfaces by grit blasting to a clean near white finish, SSC-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 hoppers, 2 ea. static mixers, 25 ft. max x 1/4" whip hose, and mastic gun with a 19 to 31 thou tip. (Applicator should consult with Denso regarding recommended equipment). Part A should be heated to 150°F and Part B heated to 150°F. Hose bundle shall be set at 145°F. A wet on wet spray technique should be used to achieve a minimum thickness of 20 mils. The coating thickness should be measured using a wet fi lm thickness gauge.
