Abstract
A method for inhibiting corrosion of a metal surface is disclosed. The method comprises contacting said metal surface with a corrosion inhibitor of the formula ##STR1## wherein R is selected from the group consisting of aliphatic radicals containing from about 6 to about 22 carbon atoms, R.sub.1 --C.sub.m H.sub.2m -- wherein R.sub.1 is alkoxy containing from 6 to 22 carbon atoms and m is an integer of from 2 to 6, and ##STR2## wherein R.sub.2 is alkyl containing from 1 to 20 carbon atoms, x is an integer of from 1 to 10 and each R.sub.3 is independently hydrogen or methyl; and R' is selected from the group consisting of hydrogen, C.sub.1 -C.sub.12 alkyl, and C.sub.1 -C.sub.12 alkoxy, at a temperature and for a period of time sufficient to inhibit corrosion of said metal surface. A method for pretreating a metal surface to improve the adhesion of paint thereto is disclosed. The method comprises contacting said metal surface with an adhesion promoter of the formula ##STR3## wherein R is selected from the group consisting of aliphatic radicals containing from about 6 to about 22 carbon atoms, R.sub.1 --C.sub.m H.sub.2m -- wherein R.sub.1 is alkoxy containing from 6 to 22 carbon atoms and m is an integer of from 2 to 6, and ##STR4## wherein R.sub.2 is alkyl containing from 1 to 20 carbon atoms, x is an integer of from 1 to 10 and each R.sub.3 is independently hydrogen or methyl; and R' is selected from the group consisting of hydrogen, C.sub.1 -C.sub.12 alkyl, and C.sub.1 -C.sub.12 alkoxy, at a temperature and for a period of time sufficient to improve the adhesion of paint to said surface. A method for painting a metal surface is disclosed. The method comprises contacting said metal surface with an adhesion promoter of the formula ##STR5## wherein R is selected from the group consisting of aliphatic radicals containing from about 6 to about 22 carbon atoms, R.sub.1 --C.sub.m H.sub.2m -- wherein R.sub.1 is alkoxy containing from 6 to 22 carbon atoms and m is an integer of from 2 to 6, and ##STR6## wherein R.sub.2 is alkyl containing from 1 to 20 carbon atoms, x is an integer of from 1 to 10 and each R.sub.3 is independently hydrogen or methyl; and R' is selected from the group consisting of hydrogen, C.sub.1 -C.sub.12 alkyl, and C.sub.1 -C.sub.12 alkoxy, at a temperature and for a period of time sufficient to improve the adhesion of paint to said surface and applying paint to said metal surface.
