  • Dielectric, radiation-curable coating compositions
    Patent number: 6506814
    Abstract: A UV-curable acrylate-thiol-ene insulating coating composition for electrical conductors, a method of manufacturing a UV-curable acrylate-thiol-ene insulating coating composition for electrical conductors. The insulating coating being of about 2.5 &mgr;m to about 500 &mgr;m thickness, which cured coating has a dielectric dissipation factor (60 Hz, 24° C.) of lower than about 0.05.
    Type: Grant
    Filed: May 7, 1998
    Date of Patent: January 14, 2003
    Assignee: DSM N.V.
    Inventors: Vadim V. Krongauz, Chau T. M. Ha, Sangeeta Rampuria
