High-Performance Metal Coating Capabilities
MIL applies epoxy primers, polyurethane topcoats, and enamel finishes engineered for corrosion resistance, durability, environmental protection, and long-term component performance. Each system is applied according to military, OEM, and industry specifications.
Spec & Capability Highlights
- MIL-spec epoxy primers (including MIL-PRF-23377)
- Polyurethane topcoats offering UV, chemical, and weather resistance
- Enamel coatings for cosmetic, protective, and high-gloss applications
- Compatible with steel, aluminum, titanium, and alloy substrates
- Supports multi-coat finishing: prime → topcoat → cure → inspection
- Controlled atmosphere curing for coating integrity
- One-stop processing: prep, coating, cure, inspection, and marking
How the Epoxy / Polyurethane / Enamel Coating Process Works
Step 1 — Surface Preparation
Parts undergo spec-driven cleaning, blasting, or pretreatment to ensure correct adhesion and coating performance.
Step 2 — Epoxy Primer Application
Epoxy coatings provide strong bonding and corrosion protection. Applied for:
- MIL-spec primer systems
- Adhesion promotion
- High-strength protective layers
Step 3 — Polyurethane or Enamel Topcoat Application
Polyurethane coatings provide:
- UV stability
- Environmental durability
- Flexible, long-wear performance
Enamel coatings provide:
- High-gloss cosmetic finish
- Excellent color uniformity
- Smooth decorative surfaces
Step 4 — Controlled Curing
Parts are cured with monitored temperature and humidity to ensure film integrity, hardness, and adhesion.
Step 5 — Inspection & Validation
Quality checks may include:
- Coating thickness
- Adhesion verification
- Visual inspection for uniformity, defects, or film integrity
- Documentation for aerospace and defense requirements
