Abstract
Compositions comprising alkanolamine salts of alkylaromatic sulfonic acids, a half acid ester of an alkyl- or alkenylsuccinic acid and a liquid medium comprising predominantly water, and, optionally, sufficient excess alkanolamine to maintain true solubility in all proportions with water provide thin, continuous, clear protective coatings for metallic substrates normally susceptible to corrosion.
Claims12
A composition dilutable in all proportions with water to form a true solution and adapted to form a clear corrosion-inhibiting coating on a metal substrate normally susceptible to corrosion, said composition consisting of either:
- (I)
- (A) a salt of
- (i) an alkylaromatic sulfonic acid and
- (ii) an alkanolamine;
- (B) a half acid ester of an alkyl- or alkenylsuccinic acid;
- and
- (C) an aqueous liquid diluent therefor;
- or,
- (II)
- (A) a salt of
- (i) an alkylaromatic sulfonic acid and
- (ii) an alkanolamine;
- (B) a half acid ester of an alkyl- or alkenylsuccinic acid;
- (C) an aqueous diluent therefore;
- and
- (D) "an effective amount of an alkanolamine which is the same or different from that defined for (A) (ii) to maintain miscibility of the composition.
