Photosensitive Liquid Repellent Coating Materials

A Coating Material That Can Form Hydrophobic (Water/Oil Repellent) Patterns by Photolithography

A photosensitive material that can form fine patterns with high liquid-repelling characteristics. Expected to be used in a wide range of fields such as printable electronics and bio/life sciences.
Furthermore, control of liquid behavior is possible by combining with hydrophilic substrates and TOK's super hydrophilic coating materials.


  • Coating material for lithographic process to create liquid repellent areas and patterns
  • Film thickness adjustable
  • Positive/negative type selectable
