Warren Safe T Plus Navy Ppg

  1. 1. 08/25/10<br />PPG/Warren Safe-T Plus <br />Single Coat<br />Rapid Return to Service Epoxy<br />
  2. 2. Business Case for Single Coat PaintsReview<br /> U. S. Navy Goals<br /> Single Coat and Rapid Cure coatings for tank and void corrosion<br /> control<br /> Applicable to all tanks and voids within the U.S. Navy<br /> 15,000 tanks and voids (~129,000,000ft2)<br /> 1,612,000 gallons of coating required for preservation<br /> $250M per year to preserve tanks and voids in fleet using current<br /> materials and processes<br />U. S. Navy Achievements<br />Single Coat coatings now approved and specified for Class 5 (fuel), Class 7 (ballast) and Class 11 (boiler/reserve feedwater)<br /> Single Coat optional in Class 13 (CHT)<br /> Single Coat still needed in Class 9 (potable water)<br />
  3. 3. Business Case for Single Coat PaintsBackground<br />Business case based on paint only. Service Life issues are not addressed, but would favor high-solids and single coat products.<br />Solvent based paints (Amercoat 235 or MIL-DTL-24441) 5-7 years in ballast tanks<br />100% Solids paints (Amercoat 133) 15-20 years in ballast tanks<br />100% Solids, single-coat paints (Safe-T Plus) 15-20 years in ballast tanks<br />
  4. 4. Single Coat Production Requirements<br /> • Surface Preparation<br /> – Same industry standard as for legacy (24441) and high solids (23236)<br /> • SSPC SP-10 (Sa2-1/2) near white metal<br /> • Soluble salts <3μg/cm2 or conductivity <30μS-cm<br /> – Employs standard commercial process/equipment<br /> • Environmental Controls<br /> – Same industry standard as for legacy and high solids<br /> • Relative humidity <50% using commercial dehumidification<br /> • Application<br /> – Commercial standardized plural component<br /> equipment (COTS)<br /> • Same equipment as for high solids.<br /> • Equipment introduced to yards beginning in 1998<br /> • Nearly all commercial applicators are certified<br />
  5. 5. The PPG Choices for Fuel, Ballast, Reserve Feed Water, CHT and Potable Water Tanks<br />216 hours to Completion<br />36 hours to Completion<br />Traditional Cure<br />UHS Coating, Ameron 133/333<br />MIL-PRF-23236, Type VII<br />(Prime, Stripe, Topcoat)<br />Rapid Cure<br />PPG/Warren SAFE-T PLUS<br />MIL-PRF-23236, Type VII <br />Single Coat Rapid Cure Coating<br />Rapid Cure<br />PPG/Warren SAFE-T PLUS<br />Single Coat Rapid Cure Coating<br />*Times include Touch-up<br />Application of Rapid Cure Coatings, 2 Full Coats & Stripe – 90 Hrs *<br />
  6. 6. Fleet Wide Cost Savings Using Single Coat, Rapid Cure Coatings Based on Remaining Composite Service Life*<br />*Projections do not include:<br />1) Submarines due to complexity of maintenance requirements and cycles, however rapid<br />Cure coating benefits as shown in this program are under investigation by SEA 07 and 92T<br />2) Auxiliary ships or MSC ships with varied contracts and schedules .<br />REFERENCE- Office of Naval Research<br />
  7. 7. Looking Aft 15 Month Inspection <br /> (US Navy Ship Oakhill)<br />
  8. 8. “The PPG/Warren SAFE-T Plus coating system in this tank, SWB 3-121-1-W, was in excellent condition, with far less than 1/10 of 1% corrosion noted at 15 month inspection.” from Navy Inspection Report. US Navy Ship Oakhill<br />
