The invention relates to a hydrophobically coated molecular sieve which comprises particles having a particle size of 1000 nm or less, the surface of the particles being coated with a silane of the general formula SiRRRR, and also to a method of producing it and to a method of using it. In addition, the invention relates to use of the coated molecular sieve and also to compositions comprising the molecular sieve and to use in producing apparatus such as, for example, electronic components and devices. 1. An electronic device comprising: {'br': None, 'sup': 1', '2', '3', '4, 'SiRRRR,'}, 'molecular sieve as a getter material, wherein the molecular sieve is a hydrophobically coated molecular sieve comprising particles of a particle size of 1000 nm or less, the surface of the particles coated with a silane having the general formula{'sup': 1', '2', '3', '4', '1', '2', '3', '4, 'wherein two or three of the radicals R, R, Ror Rbeing, independently of the others, a hydrolysable alkoxyl radical, and the remaining radicals R, R, Rand Rbeing, independently of the others, selected from the group consisting of: non-hydrolysable unsubstituted alkyl radicals, alkenyl radicals, alkynyl radicals, cycloalkyl radicals, alkylcycloalkyl radicals, aryl radicals, arylalkyl radicals,'}wherein the particles comprise inorganic particles selected from particles which comprise porous aluminophosphates, porous silicoaluminophosphates or zeolites.2. The electronic device according to claim 1 , wherein each of the hydrolysable radicals of the silane is claim 1 , independently of the others claim 1 , a hydrolysable alkoxy radical claim 1 , and the remaining radicals are non-hydrolysable alkyl radicals.3. The electronic device according to claim 1 , wherein the alkyl radicals are branched alkyl radicals having from three to eight carbon atoms.4. The electronic device according to claim 1 , wherein the particles are selected from zeolite Na-P1 (GIS structure) claim 1 , zeolite F claim 1 , and ...
