MIL-PRF-23377 revisions and versions

MIL-PRF-23377K - Version K is the latest revision of the MIL-PRF-23377 specification. This specification pertains to high-solids epoxy primer coatings that are resistant to corrosion, chemicals, and solvents, while also inhibiting corrosion. These coatings are solvent-borne and possess a maximum volatile organic compound (VOC) content of 340 grams per litre (g/L) (equivalent to 2.8 pounds per gallon [lb/gal]).

MIL-PRF-23377J - Version J was established in 2005 as part of the ongoing development of the MIL-PRF-23377 specification, with two further amendments before Version K being first used in 2012.

MIL-PRF-23377H - Established in 2002, version H Supersedes MIL-PRF-23377G.

MIL-PRF-23377G - G was one of the earlier versions of the spec, first established in 1994 and amended in 1999.
