Add-on service · Anti-fingerprint coating

Fingerprint Proof Stainless Steel

A clear nano-ceramic or polymer coating we add on top of the finish you choose. It repels oil and moisture, so fingerprints, smudges and daily stains wipe off with a soft cloth, while the metal keeps its own look.

How it works

A clear shield, added at the right step.

Smudge control: keeps the surface free from fingerprints and hand marks.

Easy to maintain: warm water and mild soap, no special cleaners.

Durable: resists corrosion, mild abrasion and daily wear.

Looks the same: the color stays; high-gloss surfaces soften slightly to a refined satin reflection.

When to add it

High-touch surfaces: elevator panels, door push plates, handrails, counters, appliance fronts.

Dark PVD colors: black, gun-grey and bronze show every print. Nano AF is available on black, Ti gold and rose gold.

Kitchens and greasy areas: range hoods, stove panels, dishwashers. Wipes clean with water.

Product housings: speaker shells, device panels, any part customers pick up.

Can skip: ceilings, high cladding and other areas nobody touches.

Two anti-fingerprint grades, tested.

Standard AF for everyday panels, nano AF where surfaces see water, grease, heat and hands all day. Figures from our quality-control tests.

Anti-fingerprint FAQ.

Questions buyers ask before adding anti-fingerprint.

Can it be applied to any finish?

Yes. It works on hairline, No.4, mirror, etched, bead-blasted and PVD-colored finishes, keeping their texture and tone.

Does it change the color or gloss?

No. The coating is clear. It may soften high-gloss reflections slightly to a satin tone, but the base color stays the same.

How durable is it?

With normal indoor use and proper cleaning, it lasts for many years and resists fingerprints, moisture and mild cleaning chemicals.

How should I clean it?

Warm water and a mild detergent with a soft or microfiber cloth. Avoid harsh solvents, abrasives and bleach-based products.

When is it applied in production?

For mirror-etched sheets, after mirror polishing and before etching. For PVD colors, after coloring as the final layer.

Is anti-fingerprint the same as anti-scratch?

Not exactly. Anti-fingerprint prevents smudges and stains; anti-scratch coatings add hardness. Some nano-ceramic formulas combine both.
