Based on the unique properties of the fluorine atom, fluorochemicals are chemicals that possess various characteristics that other organic compounds cannot achieve. DIC features a lineup of fluorochemicals that includes fluorosurfactants which possess advanced leveling capabilities.


DIC has begun offering MEGAFACE RS-75 UV-reactive fluorine-based surface modifier

MEGAFACE RS-75 is a surface modifier developed by DIC's unique additive design techniques. Adding RS-75 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.

MEGAFACE - Surfactants/Surface Modifiers

Surfactants and surface modifiers have different surface activating effects according to the materials they are added to or the methods with which they are used. DIC develops surfactants and surface modifiers according to your demands by matching them to the intended materials.


Fluorosurfactants demonstrate an excellent surfactant effect with an additive amount of 0.05 to 0.5 wt% (in solid content) based on the ease of surface segregation of fluorine-containing groups.

UV-reactive surface modifiers provide functions to repel water and oil well and to prevent the adherence of fingerprints and stains to a coating film surface.

Non-reactive surface modifiers provide various properties such as water repellency, oil repellency, stain resistance, non-adhesiveness, anti-blocking, and slipperiness to the solid surface.
