Tanks and critical spaces requiring a MIL-PRF-23236 Type VII Ultra High Solids (UHS) epoxy coating system have the option of retaining a Pre-Construction Primer (PCP) or the first coat of a multi coat Type VII UHS system throughout unit construction. PCP is not intended to last longer than 6 months, and is not a sufficient corrosion protection barrier, while UHS coatings are easy to damage and expensive to repair, making neither option an ideal coating for unit construction. MIL-PRF-23236 Type VI epoxy primers, on the other hand, are durable and easy to repair, making them a suitable candidate for retaining as a protective coating throughout unit construction. This project presents the material testing data to propose retaining a Type VI epoxy under Type VII UHS as a suitable alternative to the Type VII UHS coating system.
