    1. 1 Army Vehicle Coatings - “Smart” Implementation & Use Carl Handy - U.S. Army TACOM John Repp, P.E. - Corrpro Companies, Inc.

    2. 2 Army Coatings Use The Army Chemical Agent Resistant Coating (CARC) system serves several functions Reduced threat from chemical warfare Reduced IR signature Camouflage Reduction of corrosion

    3. 3 Current Army Vehicle Requirements Vehicles are required to operate anywhere in the world With reduced maintenance and acquisition budgets they must last longer with less upkeep Most new systems have a 20+ year life-cycle requirement The CARC system alone cannot meet this 20+ year corrosion requirement!

    4. 4 CARC Only Corrosion

    5. 5 CARC as a CPC Component CARC (and other coatings) must be used “smartly” as part of a Corrosion Prevention and Control (CPC) system Supplement coatings during fabrication (OEM) CPC maintenance procedures (Repair/Rebuild)

    6. 6 CARC as a CPC Component OEM Issues Maximize vehicle life-cycle (20+ year) Maintain CPC system with minimal maintenance CARC compatibility with other CPC materials Repair/Rebuild Issues Original CPC system removed during processing Coatings used to restore/replace original CPC Life-cycle impact (costs and readiness)

    7. 7 OEM Coatings Applied over other CPC materials (anodizing, galvanizing, etc.) Automated application Underbody/wear protection by abrasion resistant coatings Supplemental wax film and undercoating materials Coatings used to supplement/enhance CPC, not as a stand-alone system

    8. 8 Repair/Rebuild Coatings Original CPC system removed by cleaning/stripping Wheel abrader/blasting Grinding/sanding Coatings used to restore original CPC Steel - zinc-rich Aluminum - conversion coatings Final finish visually similar, but life-cycle is reduced

    9. 9 For both OEM and Repair/Rebuild activities, the following statement is true… To meet the life-cycle requirements of Army vehicles coatings must be considered as part of the CPC system, not as a replacement.

    10. 10 Successful Coating Implementation Regardless of coating activity successful implementation relies on the same conditions Good QA/QC checks Appropriate equipment/facilities Satisfying environmental concerns/regulations Maintenance impact on CPC system Producing a vehicle that is maintainable by its end user

    11. 11 QA/QC & Equipment Set checkpoints needed during preparation/ application stages Assurance that materials are properly and adequately applied Equipment is functional and fully operational Proper equipment is used for appropriate coating materials

    12. 12 Environmental VOC emissions Water based formulations E-coat or other deposition coating operations Hexavalent chromium Alternative conversion coatings Wash primer Conversion coating elimination Other HAPs and worker safety issues

    13. 13 Maintenance Considerations CPC can be supplemented by regular maintenance Washing activities Inhibitor and supplemental coating application Touch-up painting These and other procedures have varying life-cycle savings

    14. 14 End User Maintainable Straight-forward maintenance Realistic PMCS schedule to achieve life-cycle requirements Elimination of novel or non-mainstream coatings or treatments

    15. 15 Summary Coatings are an important CPC component “Smart” use of these materials can add to or help restore a CPC system Coatings need be considered from a life-cycle perspective When used correctly with other materials a 20+ year vehicle life-cycle is attainable
