MIL-PRF-23377 Primer and MIL-PRF-85285 Topcoat

Home » Technical Specifications » MIL-PRF-23377 Primer and MIL-PRF-85285 Topcoat

DiFruscia Industries applies the full mil-spec paint system in-house under Nadcap accreditation for chemical processing (AC7108) and an AS9100D quality system: pretreatment, MIL-PRF-23377 epoxy primer and MIL-PRF-85285 polyurethane topcoat, with controlled film thickness, cure and masking.

The paint system

Layer Specification What it does
Pretreatment MIL-DTL-5541 chem film or MIL-A-8625 anodize Adhesion and corrosion protection under the paint
Primer MIL-PRF-23377 High-solids epoxy primer that inhibits corrosion and anchors the topcoat. The spec includes chromate and non-chromate classes
Topcoat MIL-PRF-85285 High-solids polyurethane topcoat for aircraft and support equipment: weather, fluid and abrasion resistance with color and gloss control

How to call it out on the drawing

  • Call out the full system: pretreatment, primer and topcoat, including type, class, color and gloss (for example a FED-STD-595 color number).
  • State the film thickness for each layer, or the governing spec’s default applies.
  • Mark masking for threads, bores, grounding points and mating surfaces. See Precision Masking.
  • Chromate or non-chromate? Confirm which primer class your program allows.

CARC

DFI also has experience with Chemical Agent Resistant Coating systems, including MIL-DTL-53022 epoxy primer and MIL-DTL-53039 topcoat. Ask about your program’s requirements.
