The spreading behaviour of defined trisiloxane surfactants of general formula [(CH 3 ) 3 SiO] 2 CH 3 Si(CH 2 ) 3 (OCH 2 CH 2 ) n OCH 3 (n = 3-9) on five different solid surfaces has been investigated. Maximum spreading areas and rates are found on non-polar or slightly polar surfaces of 30 to 40 mN
The spreading behaviour of binary and ternary equimolar mixtures of siloxane surfactants of general formula [(CH 3 ) 3 SiO] 2 CH 3 Si(CH 2 ) 3 (OCH 2 CH 2 ) n OCH 3 , n = 3-9, has been investigated. The mixtures show a pronounced temperature dependence on the initial spreading rate. Mixtures imitati
