Protal 7200 by Denso

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

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.

Packaging

1 liter kit and 90 liter drums standard. Other kit sizes are available. Dual cartridge repair tubes (400 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"
