New surface treatment is a rapid, convenient, and effective method for converting unused amines and amine functional groups into neutral, noncorrosive substituted urea. Reaction proceeds at room temperature, takes only a few minutes, and leaves no corrosive residue. Surface should first be washed with alcohol to remove as much as possible of unreacted amine. Then it should be dried, since residual moisture or alcohol may consume some of treatment reagent and neutralization may then be incomplete.
