Business Case for Single Coat PaintsReview U. S. Navy Goals Single Coat and Rapid Cure coatings for tank and void corrosion control Applicable to all tanks and voids within the U.S. Navy 15,000 tanks and voids (~129,000,000ft2) 1,612,000 gallons of coating required for preservation $250M per year to preserve tanks and voids in fleet using current materials and processesU. S. Navy AchievementsSingle Coat coatings now approved and specified for Class 5 (fuel), Class 7 (ballast) and Class 11 (boiler/reserve feedwater) Single Coat optional in Class 13 (CHT) Single Coat still needed in Class 9 (potable water)
Business Case for Single Coat PaintsBackgroundBusiness case based on paint only. Service Life issues are not addressed, but would favor high-solids and single coat products.Solvent based paints (Amercoat 235 or MIL-DTL-24441) 5-7 years in ballast tanks100% Solids paints (Amercoat 133) 15-20 years in ballast tanks100% Solids, single-coat paints (Safe-T Plus) 15-20 years in ballast tanks
