  • Patent number: 5091205
    Abstract: A new method is provided to impart a hydrophilic lubriciious coating onto articles such as medical devices. A device, for example a catheter, is first contacted with a polyisocyanate solution, to provide coupling, then contacted with a poly(carboxylic acid) solution to give a coating, and is then finally oven dried. These coatings have lubricity that only becomes manifest upon exposure to water ro body fluids, and moreover, are also long lasting and have good abrasion resistance. This combination of properties is not available from other currently used or proposed coatings.

  • Patent number: 5017409
    Abstract: Spray coating, particularly flat spray coating of circuit boards. Applicant's method of conformal coating, eliminates "railroading" at the edges of the flat spray web and assures precise control of the amount of coating material placed on the circuit board surface.The method includes longitudinally advancing a pressurized coating over a surface to be coated, while simultaneously feeding the coating in a flat spray pattern, and triggering feeding "ON/OFF" so as to proportion the amount of coating being fed onto the surface and to reduce "fishtail" at the edges of the flat spray pattern.
