A world-wide steel corporation needed a long-term protection solution for their new stack. Their engineering group reached out to USI for a long-term protection option, and we offered our Duromar HPL-4323 as it needed to be a solution that offers abrasion and acid dew point corrosion protection.
A containment area and tank were being converted to hold Sodium Hypochlorite, and the existing coatings could not handle this chemical. The concrete was primed with Epoxy Sealer SP810. A 40 mil coating of 3M Scotchkote 323 was applied to prevent permeation and subsequent attack of highly aggressive solvents. Finally, Encapsulation Coating Polynox 136 coated the outside of the tank. This high performance acrylic coating has excellent elastomeric and corrosion resistantance.
3M Scotchkote Epoxy Screed RS 820, our solvent-free, high performance, resurfacing screed that protects concrete floors from abrasion and chemical attacks, was applied after the surface was prepared and primed with 3M Scotchkote Epoxy Sealer SP 810. 3M Scotchkote Epoxy Coating 162CR, a two component, solvent-free epoxy was applied over Uni-Tech MC Primer for metal areas, and 3M Scotchkote Epoxy Slip Deterrent 445, our safety surfacing system, completely reinstated a concrete ''truck island'' in an unloading area damaged by chemical attack.
A steel mill was losing 50 to 70 gallons/minute on a 10 inch chemically treated water pipeline. Metal Repair SG 527 and the larger size Stop-It pipe wrap sealed the leak and brought the water loss to a stop.
An oil company needed a half inch gap at the base of their tank chimes to be repaired and sealed. Unconventional Solutions used Viscotaq Sealant to seal the gap at the base of the tank. The Viscotaq Sealant was then covered with Viscotaq EZ Wrap for added protection.
The stainless steel Flat Top Conveyor at a major auto plant was always getting wet causing major slip hazards to assembly drivers. We cleaned and coated the conveyor with 3M Scotchkote Epoxy Coating 152 LV and we added 3M Scotchkote Epoxy Slip Deterrent 445 to offer long term safety to their workers.
The concrete walls and floor of this 150 ft × 150 ft × 15 ft secondary containment unit, which houses a 60 ft high gasoline tank, had developed cracks. Following a site survey, it was established that there were 52 vertical and horizontal cracks and joints to seal which totaled over 4800 linear feet. The areas to be repaired were grit blasted using an angular abrasive and treated with 3M Scotchkote Rubber Repair Systems Elastomer Primer. 3M Scotchkote Elastomer 80 EG was then applied.
A water treatment facility had a concrete water tank with a crack, and only had eight hours to make the repair. Viscotaq sealant was used because it requires no surface preperation, it has outstanding corrosion resistance, and it allows for a quick return to service.
This wind tower had become damaged over time and required refurbishing because it was severely corroded. The customer was looking for a high performance long-term repair solution. The steel tower was prepared by using a Bristle Blaster, which mimics the results of grit blasting, to a near white metal finish, or a NACE Grade 2. One coat of 3M Scotchkote Epoxy Primer GP 120, an epoxy high solids steel protection system, was applied to the severely corroded areas. Then, two coats of 3M Scotchkote Encapsulation Coating Polynox 136 was applied.
