Abstract
Provided herein is a composition for treating aluminum containing surfaces, wherein the composition includes a reaction product of at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof and at least one fatty acid, wherein the molar ratio of the amino group/s of the at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof and of the at least one fatty acid is 1.2:1 to 1:2, and wherein the at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof is linked to the at least one fatty acid by at least one carboxylic acid/amine salt bond and/or at least one amide bond.
