  • Coating systems
    Patent number: 9604253
    Abstract: The invention relates to a coating system, in particular a coating system containing an organometallic layer which allows the selective removal of post coating layers from substrates without detrimental impact to their “in-service” performance. The organometallic layer comprises (a) an organic polymer containing multi-chelating functionalities; and (b) a metallic agent which forms an organo metallic complex with the organic polymer containing multi-chelating functionalities and is located between an optionally coated substrate and at least one post coating layer of a coating system.
    Type: Grant
    Filed: December 14, 2012
    Date of Patent: March 28, 2017
    Assignees: Commonwealth Scientific And Industrial Research Organisation, The Boeing Company
    Inventors: Sheng Li, Stuart Bateman, Alex Bilyk, Sarah Khor, Weidong Yang, Chris Broadbent, Glenn Dalby, Randall Jahren, Matthew D Jensen

  • Ultrasonic scalar adhesion test apparatus and method for paints and finishes
    Patent number: 8667844
    Abstract: Presented is a system and method for testing the adhesion of coatings to substrates using an ultrasonic scalar. The system comprises a body, a flexible scalpel extending from said body, and a source of ultrasonic waves. The flexible scalpel applies pressure and ultrasonic waves to a coating that is removed when the adhesion of the coating to the substrate is substandard. The method comprises applying an flexible scalpel extending from an ultrasonic adhesion test device to a coating, applying ultrasonic waves through the flexible scalpel to the coating while moving across the coating, removing the coating if there is less than an acceptable adhesion of the coating to the substrate, and inspecting the coating to determine if coating was removed from the substrate.
