Crown Electrokinetics Corp. develops and sells optical switching film, which can be embedded between sheets of glass or applied to the surface of glass, or other rigid substrates such as acrylic, to electronically control opacity (DynamicTint). The Company's technology allows a transition between clear and dark in seconds and can be applied to an array of windows, including commercial buildings, automotive sunroofs, and residential skylights and windows. Its electrokinetic (EK) technology is derived from ink and microfluidic technology. Its EK film technology utilizes nanometer-sized pigment particles that are electrically charged and suspended in a liquid that is sandwiched between two clear substrates that are coated with a transparent conductor oxide (TCO) film. Its plastic films are manufactured using roll-to-roll (R2R) processing equipment. Its DynamicTint Smart Window Insert is designed for retrofitting in the domestic and international commercial real estate install base.
