MIL-DTL-53072 Chemical Agent Resistant Coating \(Carc\) System Application Procedures And Quality Control InspectionThis document covers the requirements for application and inspection of the CARC systems used on military equipment. It is required for use in the selection process of the appropriate materials and procedures for the surfaces to be painted, and provides additional application, inspection, and quality control information for the below referenced cleaning, pretreating, and coating specifications. This document does not alleviate the need for proper consideration of corrosion prevention and control \(e.g., material selection, system design, manufacturing processes, maintenance and other considerations during vehicle development and maintenance\).

3. REQUIREMENTS

3.1 Definition. Application of the CARC system consists of four distinct steps, each of which is

critical to the performance of the overall system. The steps are cleaning, pretreating, priming,

and topcoating. To ensure of CARC system adhesion, all pretreatment chemical reactions shall

be complete prior to applying primer and topcoat. The anticorrosive primers are primarily

epoxies and the topcoats are polyurethanes for exterior surfaces and an epoxy for interior

surfaces. All of the coatings in the CARC system are Qualified Products Database (QPD) items,

except for the zinc-rich coatings conforming to Commercial Item Description (CID) A-A-59745.

There is a list of suppliers and products known to meet the salient characteristics of the CID.

For the pretreatment coatings, refer to TT-C-490 for the various types and those that require

QPD. In addition, each batch of polyurethane topcoat shall be checked by the specification's

qualifying activity for validation of the spectral and specular reflectance (camouflage properties)

and Super Tropical Bleach (STB) resistance. The STB composition shall be in accordance with

MIL-DTL-12468. The local safety office, preventative medicine activity, and local medical

support facility shall be consulted prior to applying the CARC system. For miscellaneous

requirements, see section 3.8. Pertinent CARC material specifications are listed in table I. The

choice of the coating system belongs to the government and this document is not intended to

allow users to circumvent the system specified in the system requirements.
