[nanoPost] Anti-fingerprinting

Anti-fingerprinting

The technology is for the protection of metal surfaces from fingerprints by means of a thin nanocomposite layer which preserves the metal appearance.  Intelligent functionalization makes the surfaces considerably easier to clean.

Product properties

·     Water-based and low-solvent-based coating fluid for surfaces of stainless steel, copper, brass and other metals  – not suitable for glass surfaces;

·     Simple application for example by spraying or dipping – curing either at room temperature or thermal curing at 60°C to 150°C – very good bonding;

·     Transparent, unobtrusively matt, i.e. the metal character of the surface is preserved;

·     High degree of abrasion resistance;

·     High degree of chemical resistance against acids and bases (10% H2SO4, 10% sodium hydroxide);

·     Anti-bacterial (bactericidal) properties or graffiti protection also available as an option.

Effect

·     Fingerprints are less noticeable to the eye and do not leave behind any traces of oxidation (tarnishing of the metal);

·     Easier and faster cleaning: Fingerprints can be removed simply and without any residue, for example with a dry paper towel.

Impregnation of textiles

Transparent, inorganic-organic matrix composite with hydrophobic end groups in aqueous medium

Features of the layers

·     Dramatic reduction in absorption of water and oil (beading up and rolling off);

·     Reduction of the soiling behaviour of discolouring substances (including soot, coffee and red wine);

·     The feel of the product is not impaired in any way (haptics).

Effect

·     Fibres are protected by a hard, virtually transparent, thin surface film;

·     Reduction in propensity to soiling through hydrophobization and oleophobization of the surfaces.

Photocatalysis

·     TiO2 nanoparticles (anatase) in an inorganic matrix;

·     Stable interfaces on substrates and coatings.

Properties

·     Good bonding properties on metal and glass;

·     High degree of chemical resistance against solvents and acids;

·     Highly transparent due to nanoscale inorganic components;

·     Abrasion resistance comparable with glass;

·     Cost-effective application engineering e.g. by means of spray coating, dip coating, flood coating or coating of rollers.

Effect

·     Photocatalytic anatase-type titanium nanoparticles integrated in a photocatalytic non-degradable matrix;

·     Stimulation through naturally occurring UV radiation;

·     Superhydrophilic surfaces;

·     Self-cleaning effects through degrading of organic impurities and contamination;

·     Anti-microbial effect.
