Clear Chem Film Class 3 is a thin chromate conversion coating applied to aluminum for corrosion resistance while maintaining electrical conductivity. Class 1 is thicker and non-conductive, designed for maximum corrosion protection. If you’re working with electronics or need grounding paths—Class 3 is your go-to.

“Clear” in chem film doesn’t always mean invisible. It typically has a very light iridescent or faint golden tint, depending on the alloy and process. It’s subtle but visible. It’s also a good visual cue that coating has been applied.

Yes—trivalent Clear Chem Film coatings are available and fully RoHS-compliant. These are hexavalent-chrome free and meet strict environmental and health safety standards while delivering reliable performance.

Most commonly used aluminum alloys are compatible—6061, 5052, 7075, and castings too. Our team will review your specific alloy to ensure optimal adhesion and performance.

 Yes! Chem Film is often used as a conversion pre-treatment before powder coating or painting. It improves paint adhesion and adds corrosion protection beneath the finish.

Our standard turnaround is fast and efficient, depending on part volume and masking complexity. We handle both small batches and large production runs with tight quality control.

Not at all. Chem film coatings are microns thin—typically around 0.3 to 0.8 microns. It’s ideal when dimensional precision is critical.

Yes. While Class 3 coatings are thinner, they still offer excellent corrosion resistance for indoor or controlled environments. For harsh outdoor or marine exposure, we may recommend additional coatings.

Yes. We process Clear Chem Film coatings in compliance with MIL-DTL-5541 Type I & II, Class 3, and also meet ISO 9001:2015 quality standards.

Industries like aerospace, defense, electronics, and automotive rely on Class 3 coatings for components where both corrosion resistance and electrical continuity are critical.
