Description |
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. | ||
|
Uses |
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. | ||
|
Features |
• 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 |
| ||
|
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. | ||
|
Packaging |
1 liter kit and 90 liter drums standard. Other kit sizes are available. Dual cartridge repair tubes (375 ml & 50 ml) and dispensing guns available for small repair areas. | ||
|
Storage |
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. | ||
|
Cleaning |
Clean equipment with solvent cleaner (xylene 95%, butanol 5%). | ||
|
Safety |
Spray or brush under well ventilated conditions. Wear suitable protective clothing and glasses. See: MSDS for Protal 7200 "A" MSDS for Protal 7200 "B" |
