MEGAFACE RS Series is a surface modifier developed by DIC's unique additive design techniques. Adding RS Series to UV coating provides functions to repel water and oil well and to prevent the adherence of fingerprints or stains to a coating film surface.
Since it possesses UV-reactive groups, it has excellent durability because fluorine components are secured to the surface of the coating. It can be used to protect the surface of optical films and the bodies of electronic devices.
Exhibits an effect that repels oil-based pens and fingerprints
The coating will have excellent fingerprint resistance ie prevention of fingerprint markings and also easy cleaning property.
Stain-guard performance improves by UV curing under nitrogen atomosphere.
Can be effectively used for partitions between display pixels because it repels oil only on the top surface when UV-curable.
Capable of adding chemical resistance including alkali resistance to the coating surface. It can also be used effectively for negative resist such as color resists because it can add chemical resistance to only the UV exposed sections.
RS-75, which shows excellent performance in protecting the surface of optical films and electronic device bodies, and RS-72-K, a PGMEA solution suitable for resist applications.
