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.

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.
Surfaces with anti-fingerprint coatings are beneficial in a variety of electrical applications. Alfa Chemistry has the knowledge and experience to address the majority of electronic coating repellency issues. We can investigate and assist you if you have an application that would benefit from a fingerprint-free coating.

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.
