1. What is stainless steel anti-fingerprint processing?
Stainless steel anti-fingerprint treatment is a kind ofSurface modification technology, through special processes, a protective film is formed on the surface of stainless steel to reduce the adhesion of fingerprints and oil stains, while improving stain resistance and wear resistance.
2. Common anti-fingerprint processing technology
(1) Nanocoated anti-fingerprint technology
✅principle:useOleophobic and hydrophobic nanomaterials(such as silica, fluorocarbon resin) spray or impregnate to form a micro protective layer.
✅advantage:
-
Anti-fingerprint and anti-oil stain effect is significant
-
Maintain metal texture without affecting appearance
-
Resistant to light scratches
❌shortcoming: -
It may wear and tear after long-term use and requires regular maintenance
-
May fail under high temperature environment (>200°C)
(2) PVD coating (physical vapor deposition)
✅principle: In a vacuum environment, plating on the stainless steel surface by ion sputteringMetal compounds such as titanium and zirconium, forming a dense protective layer.
✅advantage:
-
Super high hardness, strong wear resistance
-
Anti-fingerprint, anti-corrosion, anti-color distortion
-
Suitable for high-end home appliances and elevator decoration
❌shortcoming: -
Higher cost
-
Color may be limited (such as gold, black, etc.)
(3) Anti-fingerprint oil (AF coating)
✅principle:useFluorin antifouling coating, ultra-thin protective film is formed by spraying or roll coating process.
✅advantage:
-
Simple construction, suitable for mass production
-
Lower cost
❌shortcoming: -
Normal durability, need to be repainted regularly
-
Not suitable for high temperature environments
3. How to choose anti-fingerprint stainless steel?
| need | Recommended technology | Applicable scenarios |
|---|---|---|
| High wear resistance, long-term use | PVD coating | High-end home appliances, building decoration |
| High cost performance and easy to construct | Nanocoating | Kitchenware, electronic products |
| Temporary protection, low cost | Anti-fingerprint oil | Temporary display, short-term pollution prevention |
4. Maintenance method of anti-fingerprint stainless steel
-
Avoid usingStrong acid and alkali cleaner, recommended to wipe with neutral detergent + soft cloth.
-
Don't use itScratch of steel wool balls or hard objects, so as not to damage the anti-fingerprint layer.
-
Check the coating condition regularly and carry out professional maintenance if necessary.
