Hydrophilic coating PHILICFINE HP

What is Hydrophilic Coating?

Hydrophilicity is a property that causes water on a surface to spread out into a thin film rather than forming droplets.
Benefits: Ensures a clear field of vision and prevents dirt from sticking to the surface

Product Features

  • Exhibits good hydrophilicity
  • Effective in dark places
  • Can be used outdoors
  • Can be used on plastics
  • High transparency
  • Select the product that match your application


Applied Example

Examples of envisioned applications

  • Prevent poor visibility due to rain on security camera protective covers or automobile side mirrors
  • Prevent poor visibility caused by water droplets on eyeglasses, sunglasses, goggles, etc.
  • Prevent spurious operations due to water droplets, by coating the cover materials on laser sensors used with automatic doors, etc.
  • Promote culture cell growth by making Petri dishes or plates hydrophilic
