Applications & Uses
- Applications
- Uses
For long-term corrosion protection of steel and concrete substrates against water, wastewater, seawater, alkaline water and acidic water corrosion. Designed to coat steel piles, sheet piles, lock gates, reservoirs, non-potable water pipelines, treatment / storage tanks, bridges and many other aggressive industrial applications.
- Application
Steel: All contaminants shall be removed from the steel surface to be coated. Remove oil, dust, and grease and other contaminants that could interfere with adhesion of the coating. Surfaces shall be free from projections, sharp edges, high points and fi llets must be ground smooth including all corners. For immersion service, prepare surfaces by grit blasting to a clean near-white fi nish, SSPC-SP 10 or NACE No. 2. For non-immersion service, use prepare surfaces using SSPC-SPC6 or NACE No.3. Appropriate angular abrasive shall be used to achieve a 2.0 to 4.0 mil (50 to 100 microns) anchor profile.
Concrete: Concrete must be cured 28 days at 77°F (25°C) and 50% relative humidity. All surfaces shall me prepared in accordance with ASTM D4258 and ASTM D4259. All voids in concrete shall be filled and repaired.
Spray: A single leg airless unit shall be used. The unit shall be a minimum of 60:1 airless pump. A wet-on-wet spray technique should be used to achieve 11 to 26 mils (280 to 660 microns). The coating thickness should be measured using a wet-film thickness gage. Mixing: Power mix both A & B separately then combine and power mix thoroughly for minimum two minutes. Do not mix partial kits.
Repairs: Surface shall be roughened approximately 1" (25mm) around all repair areas using 60 to 80 grit sandpaper and then remove remaining dust with a clean dry cloth, brush or clean compressed air. Power mix both A&B separately then combine and power mix thoroughly for minimum two minutes. Do not mix partial kits. The coating can then be brush or roll applied to specified mil thickness (not to exceed 26 mils wet film thickness). Cure times are dependent on temperature and will be extended at cooler temperatures. Note: If steel has been exposed in the repair area and fl ash rust has developed please refer to the Steel surface preparation detailed above.
- Cleaning
Clean equipment with Xylene, Toluene or equivalent solvent cleaner. If work stoppage happens, then all material must be cleared out as to not allow product to set within equipment.
