DENSO PROTAL 7200 EPOXY COATING
Denso Protal 7200 is a VOC free, 100% solids 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 field or shop. It cures very fast to allow quick handling and backfill times.
On-site protection of girth welds, tie-ins, welds for boring applications, repairs to FBE, push-back applications, station piping, fittings and fabrication. Also used for main line pipe coating, sacrificial coating for directional drill and road bore pipe, and rehabilitation of existing pipelines.
- Fast touch dry and set times.
- High temperature resistance (up to 185°F).
- High build (up to 50 mils in one coat).
- Excellent adhesion (complements FBE coated pipe).
- High abrasion resistance for drilling applications.
- Safe and environmentally friendly.
- Does not shield cathodic protection.
- Can be applied with brush, roller or spray.
- Available in a variety of packaging options.
Application : Brush
Prepare surfaces by grit blasting to a clean near white finish, SSC-SP 10/ NACE No. 2. Initially stir the base and hardener. Add the hardener to base and mix 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 gauge shall be used to measure mil thickness. If surface temperature falls below 50°F (10°C), surface must be preheated to achieve cure. Preheat may be achieved with a propane torch or induction coil. Resin and hardener component shall be kept warm, at a minimum of 68°F (20°C), to mix easily.
Application : 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, static mixers, whip hose, and mastic gun. (Applicator should consult with Denso regarding recommended equipment). 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 film thickness gauge.
1, 1.5, 1.75 and 2 liter kits and 75 liter & 800 liter kits standard. Dual cartridge repair tubes (50 ml, 400 ml & 1000 ml) and dispensing guns available for small repair areas.
Minimum 24 months when stored in original containers @ 41°F (5°C) to 100°F (36°C). On job site where temperatures are below 68°F (20°C) product must be kept warm to mix properly.
