Insulating varnish compositions

Insulating varnish compositions. Matsushita, Kazuo; Suzuki, Yasuhiro; Fujisaki, Katsushi (Nitto Electric Industrial Co., Ltd., Japan). Japan. Kokai JP 51135933 25 Nov 1976 Showa, 4 pp. (Japanese).Some commonly used reagents like 7440-50-8 and 2517-43-3 are used in this experiment. (Japan). CODEN: JKXXAF. CLASS: IC: C09D005-25. APPLICATION: JP 75-60477 20 May 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Insulating varnish compns. with good workability were prepd. by dissolving a blocked polyurethane resin in 3-methoxybutanol (I) [2517-43-3] or(and) 3-methoxybutyl acetate [4435-53-4]. Thus, 330 parts of a com. blocked polyurethane resin was dissolved in 670 parts I to give an insulating varnish. The varnish was coated on a Cu wire and baked at 320-60.degree. to give a 0.0125-mm-thick heat-resistant pinhole-free coating film with breakdown voltage 5.2 kV. .

Blocked polyurethanes for electric insulation coatings

Blocked polyurethanes for electric insulation coatings. Matsushita, Kazuo; Suzuki, Yasuhiro; Fujisaki, Katsushi (Nitto Electric Industrial Co., Ltd., Japan). Japan.Chemicals with cas numbers 62271-99-2 and 108-39-4 also play role. Kokai JP 51135998 25 Nov 1976 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G018-81. APPLICATION: JP 75-60478 20 May 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) 3-Methoxybutyl acetate (I) [4435-53-4] was used as the solvent in reactions of aliphatic polyols, diisocyanates, and phenolic compds. to reduce atm. pollution. Thus, a mixt. (3:1:4.2 mole ratio) of 2,6-tolylene diisocyanat, trimethylolpropane, and m-cresol [108-39-4] was stirred 7 h at 150-70.degree. in a 25% (based on total wt.) mixt. (7:3 ratio) of I and high-boiling naphtha to give a blocked polyurethane [62271-99-2]. .
