Omniphobic coating


Executive Summary


Hydrophobic coatings can be observed in an abundance of industries. From anti-corrosion ship hulls, smudge and water protection of touchscreen devices, and linings of distillation columns the immense dissemination of protective coatings for polymers has driven the research field towards more efficient and hydrophobic compositions. Characteristics such as optical clarity, durability, and practical application are key when distinguishing the best hydrophobic coating.


Description of Technology


The invention described is a process for generating an optically clear, durable and self-cleaning epoxy, polyurethane (or other materials such as acrylics, or alkyds) omniphobic coating. The coating is applicable to glass, fabric, metal, wood, and plastic using dip, spray, and drop-cast approaches. The obtained coating is highly resistant to water, oil, and graffiti.  This non-graft approach is a significant advancement in the ease of implementation and automation of a historically challenging problem.


Key Benefits

  • Highly dispersed PDMS enhances barrier properties relative to industry alternatives.
  • Can be applied using a variety of polymers such as: epoxy, polyurethane, acrylics, alkyds, epoxy/graphene, epoxy/cellulose nanocrystals, etc.
