Clean Surface Coatings
Surfaces routinely subjected to touch are commonly stained with
fingerprints, skin oil, sweat and cosmetics. Once a surface is contaminated,
stains are not easily removed, or cleaning materials are required. Surfaces
with antireflective coatings are very sensitive to surface contamination such
as dirt and fingerprints, which not only can cause negative impacts on
aesthetic appearance but also can result in safety issues.
In demanding applications, such as handheld electronic devices and displays,
the challenge is to obtain a fouling-resistant surface with long-term surface
performance durability. Dow Corning Clean Surface Coatings are new
alkoxysilane functional perfluoropolyether (PFPE) hybrid polymers that exhibit
the synergistic effects of the oleophobicity and low coefficient of friction of
fluoropolymers and the hydrophobicity and durability of silicone. A major
advancement of this new technology is resistance to wear by rubbing, allowing
the surface to stay cleaner for a longer period of time. The easy-to-clean
surface comes from the low surface energy of the alkoxy silane functional PFPE
polymer.
