Anti-Fingerprint Coating


Fingerprints on electronics give them an aged appearance and lower their value. Alfa Chemistry has a number of anti-fingerprint coating methods that can be used to anti-fingerprint multiple substrate types. On a number of substrates, including rough or textured metals, our anti-fingerprint coatings bind to a variety of surfaces and dramatically improve hiding power and ease of cleaning. These ultra-thin nanoscale coatings are both optically transparent and exceedingly robust, providing numerous performance benefits in a wide range of applications.

Why Do You Need An Anti-Fingerprint Coating?

Surface coating technology that is anti-fingerprint can be used to solve a wide range of issues. The following examples demonstrate how AFP coating can assist improve product quality.

  • Fingerprints are unsightly and have a detrimental impact on consumer satisfaction.
  • Cleaning your surfaces takes time, money, or is impossible.
  • The quality of touchscreen displays can be harmed by fingerprints.
  • The performance of optics can be harmed by fingerprints.
  • Without chemical cleansers, fingerprint oil or other pollutants are tough to remove.

Alfa Chemistry can provide a variety of anti-fingerprint coatings for electronics, including but not limited to:

Surface Coatings Containing Fluorinated Polyethers

We offer a transparent fluoropolymer coating that resists water and oil without altering the appearance of substrates such as glass by generating a thin monolayer on the surface, which reduces fingerprints and makes the surface easier to clean.

In addition, the coating is heat resistant, wear-resistant, and has a low friction coefficient.

Coating Features:

  • <10nm film thickness
  • Low friction
  • Waterproof and oilproof
  • Anti-fouling, anti-fingerprint
  • High wear resistance
  • Non-flammable

Examples of coating applications:

  • Touch panel
  • Mobile phone case
  • Release agent
  • Antifouling of metals, plastics, etc.
