  • Conformal coating, composition and method for the mitigation of growth of metallic crystalline structures
    Patent number: 10731042
    Abstract: A nanocomposite coating composition for use in the mitigation of whisker growth from a metallic surface (82) includes a polymer matrix (86) comprising a base polymer and insulating material nanoplatelets (85), for example clay nanoplatelets, within the polymer matrix (86). A conformal coating (84) for application to a metal surface (82) is formed from the coating composition. The conformal coating mitigates the spontaneous growth of whiskers (83), in particular tin whiskers, from the coated surface (82), reducing the risk of short-circuits caused by such whiskers bridging gaps within electronic devices. Methods are provided for the preparation of coating compositions and coatings.
