Abstract:

Touch-up painting is performed in the field to restore the authorized coatings applied on US Army and other US Military ground equipment platforms. However, due to the requirements for cure of the specified high temperature coatings for steel substrates (MIL-PRF-14105) they cannot be applied in a field setting. This precludes their use by Soldiers during touch-up painting operations (performed in accordance with Technical Manual 43-0242) and often results in improper cure of these coatings, even when applied at a Logistics Readiness Center, Materiel Maintenance Division, and other organic re-paint facilities within the Army, due to a lack of facilities to bake these parts. This results in either touch-up painting not being performed or premature failure of these coatings on exhaust systems and other components leading to corrosion of the underlying steel substrate. There is a need for touch-up coating products that can be used in high temperature applications. This report evaluates a selection of commercially available high temperature coatings for touch-up applications.
