Fingerprint resistant coatings for stainless steel substrates

Friday, 25 August 2017

Fingerprints on stainless steel surfaces of household appliances such as refrigerators or ovens can be very unsightly. In a study, Turkish researchers have developed coatings with anti-finger print features for stainless steel substrates.

Coatings with tailored surface roughness were demonstrated which provide these properties.

Suitable for daily activities

Polyurethane coatings were produced by incorporation of matting agents with different particle size and surface chemistry. Depending on the amount of incorporated matting agents and their particle size, the scientists were able to obtain anti-finger print coatings with the designed surface patterns. Chemical resistance tests of the coatings proved that they are chemically durable to be utilised in daily activities.

The study is published in: Progress in Organic Coatings, Volume 112, November 2017, Pages 51-56
