Abstract

Det fluortensidfrie, langtidsstabile og biologisk nedbrytbare additivet for kromsyreløsninger har en reduserende innvirkning på overflatespenningen og bedrer således kromutskillingen, særlig i forbindelse med elektroiyttisk forkromning. Foretrukne additiver er CH(CH)S0H og salter derav, med n = 10 til 18.The fluorosurfactor-free, long-term stable and biodegradable additive for chromic acid solutions has a reducing effect on the surface tension and thus improves the chromium precipitation, especially in connection with electrophytic chromium plating. Preferred additives are CH (CH) SOH and salts thereof, with n = 10 to 18.
