Curable resin compositions

Curable resin compositions. Honda, Kyoshi (Dainippon Ink and Chemicals, Inc., Japan). Japan. Kokai JP 52030890 8 Mar 1977 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F299-00. APPLICATION: JP 74-87899 31 Jul 1974. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) A curable resin compn. is prepd., contg. acrylate monoesters 20-55, acrylate polyesters 5-30, vinyl compds. (copolmerizable with acrylic compds.) 0-20, unsatd. resins 30-75, and arom. amines (based on 100 parts resin compn.) 0.05-2.0 parts. Thus, a mixt. of Me methacrylate [80-62-6] 40, ethylene glycol dimethacrylate [97-90-5] 8, unsatd. polyesters Polylite ODR 449 [55069-49-3] 52, and N,N-bis(2-hydroxypropyl)-p-toluidine [38668-48-3] 0.1 part was stirred to give a soln. which (20 parts) was mixed with 0.5 part Bz2O2, giving a curable resin compn.

Primer compositions for coating of floors and walls

Primer compositions for coating of floors and walls. (Mitsubishi Rayon Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58204057 A2 28 Nov 1983 Showa, 7 pp. (Japanese). (Japan). 97-90-5 and 80-62-6 are cas registry numbers. These chemicals are also mentioned in this article. CODEN: JKXXAF. CLASS: IC: C09D003-727; C08F299-02. ICA: C08G059-16. APPLICATION: JP 82-88418 25 May 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The primer compns. are mixts. of 30-60% b-hydroxy esters and 40-70% unsatd. monomers [contg. >80% Me methacrylate (I)] which contain 0.1-5% paraffins and/or waxes m. >40° and 0.1-5% tertiary amines. The b-hydroxy esters are prepd. by the reaction of a bisphenol A-epichlorohydrin epoxy resin with (meth)acrylic acid and a mixt. of 80-100 mol% C8-20 satd. monocarboxylic acids and 0-20 mol% C8-20 unsatd. monocarboxylic acids. Thus, 2000 parts epoxy resin was dissolved in 975 parts I contg. 5 parts 2,4-dimethyl-6-tert-butylphenol at 70°, mixed with 27 parts Et3N, heated to 80°, mixed with 112 parts methacrylic acid and 130 parts lauric acid during 2 h, stirred 8 h at 80°, mixed with 250 parts I, stirred (68 parts) with 31 parts I, heated to 50°, mixed with small amts. of paraffin and N,N'-di(2-hydroxypropyl)-p-toluidine [38668-48-3], cooled, mixed (100 parts) with 3 parts Bz2O2, and coated on a concrete block to form a coating having good adhesion. .
