Flexible thermally stable tapes

Flexible thermally stable tapes. Su, Wei Fang Anne; Sattler, Frank Anton (Westinghouse Electric Corp. , USA). Eur. Pat. Appl. EP 110582 A1 13 Jun 1984, 24 pp. DESIGNATED STATES: R: DE, FR, GB, IT. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: H02K003-30; H02K015-12; H01F027-32; H01F041-12; H01B003-42. APPLICATION: EP 83-306661 2 Nov 1983. PRIORITY: US 82-438425 2 Nov 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 42 A tape useful for bonding elec. coils is impregnated with an insulating varnish contg. alkyl acrylates and alkyd resins modified with 329 equiv.% fatty acids. Thus, a 65% oil-length alkyd was prepd. from tris(2-hydroxyethyl) isocyanurate 53.4, soya fatty acid 30.0, and 1:4 maleic anhydride-isophthalic acid 16.6 equiv.%. A solventless varnish was prepd. from 70 g resin, 15 g trimethylolpropane triacrylate [15625-89-5], and 15 g tetraethylene glycol diacrylate [17831-71-9]. Glass cloth was impregnated with the varnish and baked 10 min at 160° to give tapes retaining 68.4% elec. strength after 1 wk at 180° and with stiffness drape flex 7.4 cm.

DE 3346034 A1 12 Jul 1984, 38 pp. (German).Some chemicals with cas registry numbers like 19111-68-3 are also used. (Germany). CODEN: GWXXBX. CLASS: IC: C08F002-50; C08F220-20; C08F265-06. APPLICATION: DE 83-3346034 20 Dec 1983. PRIORITY: JP 82-223277 20 Dec 1982; JP 83-39399 10 Mar 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Photocurable compns. useful in printed circuits, printing plates, etc. contain polyunsatd. compds., thermoplastic binders, photocuring initiators, and thioamides or thiohydrazides. Thus, a mixt. of poly(Me methacrylate) [9011-14-7] (mol. wt. 140,000) 15.0, tetraethylene glycol diacrylate [17831-71-9] 6.1, trimethylolpropane triacrylate [15625-89-5] 2.4, p-MeC6H4SO2NH2 1.62, p-MeOC6H4OH 0.01, malachite green 0.015, (p-Et2NC6H4)2CO 0.04, Ph2CO 0.15, PhSO2CBr3 0.37, MEK 45, and CH3CSNHNH2 [62543-18-4] 0.0066 g was coated to 50 m (dry basis) on polyester film, dried 2 min at 100°, laminated to a Cu-coated substrate at 120°, and exposed to a 2-kW, high-pressure Hg lamp at a distance of 50 cm for 10 s to give a film with crosshatch adhesion 90%, compared with 20 without the thiohydrazide. .
