- 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
