Protal 7200

Fast Cure, High Build Pipeline Coating

Denso LogoProtal 7200 is a VOC free, 100% solids, 2 part epoxy coating specially formulated to compliment FBE coated pipe. It is a high build liquid coating that is brush or spray applied in one coat in the fi eld or shop. It cures very fast to allow quick handling and backfill times.

Uses

On-site protection of girth welds, tie-ins, welds for boring applications, repairs to FBE, push-rack applications, station piping, fittings and fabrication. Also used for main line pipe coating, sacrificial coating for directional drill (ARO) and road bore pipe, and rehabilitation of existing pipelines.

Features

  • Fast touch dry and set times
  • High temperature resistance up to 203°F (95°C)
  • High build (up to 70 mils / 1778 microns in one coat)
  • Excellent adhesion (compliments FBE coated pipe)
  • High abrasion resistance for drilling applications
  • Can be used as an abrasion resistant coating (ARO)
  • Safe and environmentally friendly
  • Does not shield cathodic protection
  • Can be applied with brush, roller or spray
  • Available in a variety of packaging options
  • Meets AWWA C-210-92 Standard
  • Outstanding self-leveling characteristics
  • CSA Z245.30 compliant

Application


Brush
Prepare surfaces by grit blasting to a clean near-white finish, SSPC-SP 10 / NACE No. 2. Appropriate angular grit shall be used to achieve a 2.5 to 5 mil (63 to 127 microns) anchor profile. Initially stir the base and hardener. Add the hardener to base and mix at a slow speed until a constant colour is achieved making sure all sides of container are scraped. Apply 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 more easily.

Spray
Prepare surfaces by grit blasting to a clean near-white finish, SSPC-SP 10/ NACE No. 2. Appropriate angular grit shall be used to achieve a 2.5 to 5 mil (63 to 127 microns) anchor profile. The equipment shall be a XP70 Plural Component Sprayer or similar designed to mix and atomize 100% solids epoxies. Please refer to the Protal 7200 Plural Spray Application Specification for equipment details. Part A should be heated to 140°F – 160°F (60°C – 71°C) and Part B heated to 100°F – 110°F (38°C – 43°C). Hose bundle shall be set at 140°F – 150°F (60°C – 65°C). A wet on wet spray technique should be used to achieve a minimum thickness of 20 mils (508 microns). The coating thickness should be measured using a wet-fi lm thickness gauge. The equipment settings are only guidelines and may vary based on equipment.
