MIL-Spec Prime & Paint Services

High-precision MIL-spec prime and paint application for aerospace, defense, and industrial components requiring proven durability, corrosion protection, and strict adherence to technical specifications.

Spec-Driven Prime & Paint for Critical Components

MIL applies a range of MIL-spec primers, topcoats, and specialty coatings to support corrosion resistance, adhesion, environmental protection, and color/finish requirements for high-reliability metal parts.

MIL’s large portfolio of prime approvals and Nadcap-accredited processes ensures every coating system is applied consistently, repeatably, and in full compliance with the relevant specification.

Prime & Paint System Highlights

  • MIL-PRF-23377 (epoxy primer)
  • MIL-PRF-85285 (polyurethane topcoat)
  • MIL-DTL, AMS, and OEM prime specifications
  • Chrome-containing and chrome-free systems
  • Color-matched finishes per spec
  • Precision masking for complex geometries
  • Full documentation and traceability
  • Ideal for corrosion protection, wear resistance & environmental durability

How MIL-Spec Prime & Paint Application Works

Step 1 — Surface Preparation

Surface preparation is performed according to specification to ensure coating adhesion and long-term performance. This may include:

  • Solvent cleaning
  • Abrasive blasting
  • Chemical pretreatments (such as chem film or anodize)
  • Precision masking

Step 2 — Primer Application

A spec-defined primer is applied to promote adhesion, inhibit corrosion, and establish a uniform base layer. Primer selection is driven by:

  • Substrate material
  • Environmental exposure
  • Specification type and class
  • System-level coating requirements

Step 3 — Topcoat Application

MIL applies polyurethane, enamel, or specialty topcoats defined by military or OEM specifications. These coatings provide:

  • Color requirements
  • Chemical resistance
  • UV stability
  • Environmental protection

Step 4 — Curing & Atmosphere Control

Coated parts are cured in controlled conditions to ensure proper film formation, adhesion, and environmental durability.

Step 5 — Inspection & Verification

Every job includes quality checks such as:

  • Coating thickness measurement
  • Adhesion testing (as required)
  • Visual inspection for uniformity, defects, or coverage issues
  • Documentation & certification aligned to spec

Why Work With MIL for MIL-Spec Painting?

Proven Specification Expertise

MIL has decades of experience in interpreting OEM drawings, military specifications, and special process requirements, ensuring coatings are applied exactly as intended.

One-Stop Processing for Complex Components

Prime and paint is often only one step in a multi-process workflow. MIL combines coatings, metal finishing, NDT, and other services under one roof to reduce handling, lead times, and risk.
