  • Self-lubricating enameled wire
    Patent number: 6534717
    Abstract: A enameled wire having 100 parts by weight of a polyamide-imide resin, 1 to 5 parts by weight of a lubricant, 1 to 200 parts by weight of a masking agent-stabilized isocyanate, and 1 to 30 parts by weight of a silane coupling agent are dissolved or dispersed in a solvent to prepare a coating composition. The coating composition is then coated directly or through other insulator on the circumference of a conductor, and the coating is then baked to form a lubricating layer.
    Type: Grant

  • Self-lubricating enameled wire
    Publication number: 20020043391
    Abstract: 100 parts by weight of a polyamide-imide resin, 1 to 5 parts by weight of a lubricant, 1 to 200 parts by weight of a masking agent-stabilized isocyanate, and 1 to 30 parts by weight of a silane coupling agent are dissolved or dispersed in a solvent to prepare a coating composition. The coating composition is then coated directly or through other insulator on the circumference of a conductor, and the coating is then baked to form a lubricating layer. Thus, a self-lubricating enameled wire is prepared which has excellent lubricity, abrasion resistance, and adhesion to varnish as a treating agent.
