Chemical Conversion Excellence

Delivering high-performance surface protection and enhanced functionality through precise, industry-grade chemical conversion coatings.

At SM Finishes, our chemical conversion coating services are designed to provide exceptional corrosion resistance, improved paint adhesion, and extended service life for a variety of metal substrates. Using advanced surface treatment techniques, we create a uniform, tightly bonded protective layer that meets the most demanding industrial requirements while maintaining dimensional accuracy and performance integrity.

Why Our Chemical Conversion Stands Out

We combine technical expertise with stringent process control to ensure consistent, high-quality finishes that meet both functional and aesthetic needs.

  • Optimized Corrosion
  • Paint & Adhesive Bonding
  • Non-Reflective, Low-Glare Finishes
  • Dimensional Stability
  • MIL, ASTM, and ISO Standards
  • Versatile Applications

Our process is tailored for industries where performance, reliability, and compliance are critical — from defense and aerospace to electronics and precision engineering. Every project is executed with a focus on quality, durability, and exact specification matching.

Precision & Craftsmanship

Every chemical conversion coating we deliver reflects our dedication to detail and technical accuracy. From meticulous surface preparation to controlled chemical baths, we ensure each component receives a consistent, defect-free finish that meets the exact performance and compliance standards required by your industry

Applications

Ideal for protecting aluminum, magnesium, and other metals in aerospace, automotive, defense, and industrial equipment where longevity and surface integrity are essential.

Questions? You’re covered

We’ve gathered answers to the most common questions to help you understand our services, processes, and quality standards with ease.

Chemical conversion coating is a surface treatment process that creates a protective, corrosion-resistant layer on metals like aluminum and magnesium. It also improves paint adhesion and extends component lifespan.
No, the coating is extremely thin, typically in the range of 0.5–5 microns, so it does not alter the dimensions or tolerances of the treated parts.
Yes, our processes comply with stringent industry specifications, including MIL-DTL-5541 and other aerospace, defense, and industrial requirements.
