scope:
This specification covers processes, pretreatments, and pre-primer surface preparations of metallic substrates for coating applicators. It covers metal surface preparation for delaying corrosion initiation and promoting primer adhesion. In addition, this specification covers the testing requirements for qualification of conversion coatings, the pretreatments and pre-primer coatings. Additional qualification requirements may be required based on each specific application. Unless otherwise specified in the contract, the Supplementary Requirements (Appendix A) section covers cleaning, and pretreatment by chemical conversion of ferrous metals and zinc/zinc alloy coated metals and provides specific requirements for applying Non-Chemical Agent Resistant Coatings (Non-CARC), such as a single coat ammunition coating
intended Use:
This specification is intended to provide the acceptable methods for cleaning, surface preparation, conditioning and pretreatment of metals prior to the application of the CARC and non CARC... View More
