Kokai JP 52022029 19 Feb 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09D003-81. APPLICATION: JP 75-97474 13 Aug 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 55 Nitrocellulose (I) [9004-70-0]-contg. acrylic resin lacquer was mixed with acrylonitrile derivs. and piperidine derivs. to improve the yellowing resistance of the lacquer. Thus, 100 parts of a lacquer comprising I 4.6, an acrylic resin 18.4, di-Bu phthalate 1. 52829-07-9 and 9004-70-0 are cas registry numbers of chemicals which are used as reagents here.3, EtOAc 15.3, BuOAc 11.9, iso-PrOH 11.0, and PhMe 37.5 parts was mixed with 1.4 parts ethylhexyl diphenylmethylenecyanoacetate (II) [6197-30-4] and 0.4 part bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate [52829-07-9], sprayed on a white enamel-coated steel panel and dried to give a coating having superior discoloration resistance to that of a similar coating contg. 1.8 parts II alone. .

Ultraviolet absorbent silicone based emulsions for vinyl polishes

Ultraviolet absorbent silicone based emulsions for vinyl polishes. Thimineur, Raymond J.; Traver, Frank J. (General Electric Co., USA). Can. CA 1176828 A1 30 Oct 1984, 24 pp. (English). (Canada). CODEN: CAXXA4. CLASS: IC: C09K015-32. APPLICATION: CA 82-399400 25 Mar 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Polishes for vinyl surfaces imparting good protective finishes are based on silicone emulsions contg. a UV-absorbent compd. Thus, an emulsion was prepd. contg. Viscasil 60,000 388, SF-96 (100) 328, SF-96 (1000) 284, and Uvinul N539 [6197-30-4] 10 g. The compn. was emulsified in water using a mixt. of ionic and nonionic surfactants. The emulsion was applied to a vinyl surface and buffed. The vinyl surface was exposed in a Weather-O-Meter 332 h, and the gloss and appearance retention remained very good.
