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 finish, SSPC-SP 10 or NACE No. 2. For non-immersion service, prepare surfaces using SSPC-SPC6 or NACE No.3. Appropriate angular grit 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 68:1 airless pump. A wet-on-wet spray technique should be used to achieve 11 to 22 mils (280 to 559 microns). The coating thickness should be measured using a wet-fi lm thickness gage.
Mixing: Power mix both A & B separately then combine and power mix thoroughly for two minutes. Do not mix partial kits.
- 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.
