Spec-Driven Powder Coating for Long-Lasting Performance
Powder coating is a dry finishing process that provides uniform, durable, and environmentally resilient protection for metal components. Applied electrostatically and cured under heat, powder coatings form a strong, continuous film that resists corrosion, wear, abrasion, and environmental exposure.
MIL delivers powder coating solutions with the repeatability, spec compliance, and process control required for mission-critical parts, ensuring every component meets OEM and MIL-spec standards.
Powder Coating Highlights
- MIL-spec and OEM-approved powder coating systems
- Uniform film thickness and color consistency
- Excellent corrosion, abrasion, and impact resistance
- Strong adhesion on aluminum, steel, and specialty alloys
- Environmentally friendly, solvent-free application
- Ideal for cosmetic, protective, and functional requirements
- Repeatable curing cycles for tight tolerance parts
How the Powder Coating Process Works
Step 1 — Surface Preparation
Proper surface preparation ensures long-term film adhesion and uniform coverage. Depending on the specification and substrate, MIL performs:
- Precision cleaning and degreasing
- Abrasive blasting or mechanical surface prep
- Pre-treatment coatings such as chem film or anodize
- Custom masking for tight-tolerance or functional surfaces
Step 2 — Electrostatic Powder Application
The powder is applied via controlled electrostatic spray, which ensures:
- Even coating distribution
- Strong electrostatic attraction to metal substrates
- Precise, repeatable film build within spec requirements
Step 3 — Thermal Curing
Components are oven-cured to chemically crosslink the coating, resulting in a durable, cohesive film that withstands:
- Corrosion
- Abrasion and impact
- Exposure to chemicals, moisture, and UV
- High-use and high-wear environments
Step 4 — Final Inspection & Verification
MIL conducts rigorous quality checks, including:
- Film thickness measurement
- Adhesion verification
- Cure confirmation
- Surface appearance review
- Spec compliance documentation
