摘要:
A process for multi-coat painting by the electrophoretic application of a primer on a conductive substrate, stoving the primer coat obtained, coating with a colouring and/or effect-providing undercoat and application of a coat of clear lacquer and stoving the undercoat and clear lacquer topcoat, in which a colouring and/or effect-providing undercoat on an aqueous base is applied directly to the stoved primer without the application of other intermediate coats, said undercoat containing one or more water-dilutable binders and one or more polyisocyanates with free or blocked isocyanate groups, where the hydroxyl number of the binder solids in the aqueous undercoat is 10 to 300 mg KOH/g and the ratio of the number of free or blocked NCO groups to that of the hydroxyl groups arising from the binder solids is over 0:5:1 and under 5:1.
摘要:
A lotion comprising a tricyclic compound represented by 17-allyl-1,14-dihydroxy-12-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.04,9]octacos-18-ene-2,3,10,16-tetrone or a pharmaceutically acceptable salt thereof, a dissolution/absorption promoter, a liquid medium, and optionally an emulsifying agent or a mixture thereof with a thickening agent. The lotion is stable and excellent in absorbability, scarcely irritates the skin, and can be sustainedly released. It is useful for treating and preventing inflammatory and proliferative dermatoses and immunologically mediated skin diseases.
摘要:
A process for producing an N-tert-butyl-2-pyrazinecarboxamide represented by general formula (2) by the reaction of a cyanopyrazine represented by general formula (1) with tert-butyl alcohol in the presence of sulfuric acid; and a process for producing an N-tert-butyl-2-piperazinecarboxamide represented by general formula (3) by the hydrogenation of an N-tert-butyl-2-pyrazinecarboxamide represented by the above general formula (2) in the presence of Raney nickel or Raney cobalt.
摘要:
A synthetic lubricating oil based on an aliphatic polyester derivative having repeating units represented by general formula (I), wherein R?1 and R2¿ are as defined in the specification, and a molecular weight of 300 to 2000. This lubricating oil is excellent in the compatibility with a refrigerant and in the lubricity, which renders it suitable as a lubricating oil for a refrigerator, particularly a compression refrigerator.
摘要:
A compound represented by general formula (I) or a salt thereof, excellent in parasiticidal activity as an enthelmintic for animal and man, wherein A represents benzyl which is appropriately substituted or phenyl which may be appropriately substituted; A represents benzyl or phenyl each of which may be appropriately substituted; B and D represent each lower alkyl; and C represents hydrogen or lower alkyl.
摘要:
An environmentally-friendly process for coating metal substrates is disclosed. The metal substrate undergoes a preliminary phosphating treatment followed by a subsequent passivating treatment; the phosphating is done with a phosphating solution containing no nickel and/or the passivating treatment is carried out in the absence of hexavalent chromium. The metal substrate which has been thus treated undergoes electrophoretic dipcoating using an electro-dip coating containing bismuth lactate and/or bismuth dimethylol propionate but no tin.
摘要:
A binder composition suitable for coating agents, containing A) 20 to 77 wt.% of binder based on oligomeric or polymeric polyol compounds with a hydroxyl number from 80 to 300, an acid number of 0 to 30, a number average molecular weight (Mn) of 500 to 10,000 and a glass temperature of -20 to + 70 DEG C; B) 77 to 20 wt.% of a cross-linking agent based on aliphatic and/or cycloaliphatic polyisocyanates, C) 3 to 20 wt.% of carboxyl group-containing oligo or polyesters as a catalyst resin with an acid number of 210 to 300 mg KOH/g and a number average molecular weight (Mn) of 420 to 3,000, and one or more organic solvents and/or water.
