  • Durable, electrically conductive polyurethane compositions and methods of applying same
    Patent number: 11649375
    Abstract: A polyurethane composition suitable for coating a surface of a substrate. The polyurethane composition can include an aliphatic polyester urethane matrix and a fluorinated ionic antistatic additive. The aliphatic polyester urethane matrix can comprise an aliphatic diisocyanate, a polyester polyol having a polyester diol and a polyester triol, and sulfonated polyester urethane polyol.
    Type: Grant

  • Transparent polyurethane protective coating, film and laminate compositions with enhanced electrostatic dissipation capability, and methods for making same
    Patent number: 9580564
    Abstract: The present invention is embodied in a transparent, polyurethane laminate or multi-layer coating comprising a first transparent polyurethane layer, a middle conductive material layer disposed on the first transparent polyurethane layer, and a second transparent polyurethane layer disposed on the conductive layer. In one embodiment, the subject invention addresses the problem of static charge buildup on aircraft transparencies by allowing charge to drain through the second transparent polyurethane layer to the conductive material layer and then to the edge of the conductive material layer, where it is mated to the airframe. The present invention is also embodied in a method for forming a transparent polyurethane laminate on a transparent substrate and a method for forming a free-standing laminate.
