Compositions to remove oily substances from substrates amd their use
摘要:
Compositions utilized to remove traces of organic solvents and/or oils from the surfaces of components comprising:

i) perfluoropolyethers;
ii) fluorinated additive having a structure selected from the following:

        T-OR f (CFY)-L     (I)



        L-CF 2 OR f CF 2 -L     (II)

with L= X-CH 2 CH 2 (OCH 2 CH 2 ) n B wherein X=CH 2 O, CH 2 NR'', CONR'', CH 2 OCH 2 CH 2 NR'', CH 2 OCOCH 2 O; B= OH, SH, NHR'', OCH 3 , OCOCH 3 ;
with R''= H, alkyl C 1-3 ; Y= CF 3 or F; T is selected among -CF 3 , -C 2 F 5 , -C 3 F 7 , ClCF 2 CF(CF 3 )-, CF 3 CFClCF 2 -, ClCF 2 CF 2 -, ClCF 2 -;
R f is a perfluoropolyether chain, a perfluoroalkyl or a hydrofluoroalkyl.
