Product Description
The MIL-PRF-23377 performance specification covers the requirements for corrosion inhibiting, chemical and solvent resistant, solvent-borne, high-solids epoxy primer coatings that have a maximum volatile organic compound (VOC) content of 340 grams per liter (g/L)(2.8 pounds per gallon [lb/gal]) as supplied by the manufacturer. This specification is approved for use by all Departments and Agencies of the Department of Defense.
Composition: The primer coatings shall consist of two or three components, as follows:
Component A – a base component composed of epoxy resin and solvents.
Component B – epoxy polyamide primer; a curing agent containing polyamide or amine resin and solvents.
Component C (optional) – thinning component composed predominately of organic solvents.
Component B shall act as the curing agent for component A.
The components of MIL-PRF-23377 high solids epoxy primer shall be packaged separately and furnished as a kit. Pigments may be included with either component A or B. When the components are mixed in the proportions specified by the manufacturer, a primer coating meeting the requirements of this specification shall result. Chlorinated solvents, except for para-chlorotrifluoromethylbenzene or equal, shall be prohibited in the formulation of these primer coatings. Incidental cadmium and cadmium compounds shall be not greater than one part per million (ppm). The non-volatile portion shall contain not more than 0.05 percent by weight of lead metal or lead compounds.
