KING GUIDE TO RUST PREVENTIVES

The tremendous cost to society due to rustand corrosion of metals has in the past andcontinues today to energize research intobetter corrosion preventives. King Industrieshas been a leader in new technologies de-signed to preserve metals for over a half of acentury. This product guide has been de-signed to keep you informed of some thelatest technologies available from King whileproviding useful information about NA-SUL®

rust and corrosion inhibitors, long recognizedas the performance standard for unexcelledprotection.

For over six decades King Industries’sNA-SUL dinonynaphthalenesulfonates havebeen used in hundreds of formulations be-cause of their unique abilities as hydrophobicpolar compounds to prevent rust and corro-sion. Unlike, other sulfonates, NA-SUL prod-ucts are high molecular weight syntheticswith a narrow molecular weight distributionthat results in:

• Extremely hydrophobic coatings

• Coatings that resist reemulsification re-pelling water for long time periods

• Batch to batch consistency with highquality predictable performance

Additionally, as markets needs have changedand the quest for more environmentally andhealth friendly additives has become preva-lent, King has kept pace with those trends by:

• Developing a unique line of rust preven-tive additives for aqueous systems

• Developed additives specifically designedto be used with vegetable based oils

• Developed a 100% ashless non-sulfonate

corrosion inhibitor that is>90% biodegradable

Perhaps, just as important as the product ad-vances in rust preventive technology is acompany’s commitment to provide the techni-cal service and expertise to support thoseproducts. That is why King maintains a stateof the art, RP technical service lab that in ad-dition to expected North American test equip-

ment has unexpected equipment such as aKesternich Cabinet to fulfill different test re-quirements from different parts of the world.

Rust and Corrosion Preventive Additives

King Industries NA-SUL® rust preventive additives are based on salts of dinonylnaphthalenesulfonate(DNNS®) with additional polar compounds chosen to provide rust preventive synergy. This results inextremely hydrophobic rust preventive coatings that effectively exclude water and air from reachingthe metal surface. The resulting performance advantage allows levels of metal protection thatcompetitive additives cannot achieve and /or reductions in additive use level that result in significantformulation savings. In addition, King Industries offers a line of specialty rust and corrosion inhibitorsbased on non-sulfonate chemistry under the K-CORR® brand.

Neutral Barium dinonylnaphthalenesulfonate,50% active in light naphthenic oil.

Used for moderate indoor or sheltered outdoor storage of steel pieces. NA-SUL

BSN is particularly useful for stacked or coiled steel because of superiornon-staining properties. It is well suited for dewatering fluids because of inherentwater displacing properties and no tendency to gel from water contamination.

NA-SUL BSN

NA-SUL 729 Neutral Calcium dinonylnaphthalenesulfonate,50% active in light naphthenic oil.

Used for moderate indoor or short term outdoor sheltered storage of steel pieces.NA-SUL 729 is well suited for general purpose rust preventives as well asdewatering fluids. It is chemically neutral, which makes NA-SUL 729 a goodchoice where water or alkaline contamination is likely. Known or likelycontaminants should always be checked for compatibility with any additive system.

NA-SUL

CA-1082

A 67% active complex of Calcium DNNS/carboxylatein light naphthenic oil.

The synergy of polar materials used in NA-SUL CA-1082 allows for long termmetal protection in indoor or outdoor sheltered storage. It has excellent solubilityin most conventional diluents, but rust preventive performance is best innaphthenic or Group I paraffinic oils. It does not contain oxidized petrolatum,which improves solubility and reduces odor. NA-SUL CA-1082 does not gel oncontamination with water, but can gel if contaminated with highly basic materialssuch as caustic cleaners. For this reason it is not generally used in dewateringfluid applications. NA-SUL CA-1082 is easy to emulsify due to its acid value sothat it may be used in water-based rust preventives or as a rust preventive boosterfor metalworking fluids.

NA-SUL CA-1183 is a very effective rust preventive that does not contain oxidizedpetrolatum. This results in excellent solubility in a wide variety of base fluids suchas highly refined mineral oils, polyalphaolefins and vegetable oils. The lack ofoxidized petrolatum also results in a very mild odor. NA-SUL CA-1183 is highlyrecommended for applications such as dewatering fluids where watercontamination is likely. It has very good salt fog performance and outstandinghumidity performance. It is recommended for moderate to long term indoor andsheltered outdoor storage applications.

A water soluble rust preventive based on triethanolamine DNNS, carboxylicacid and alkanolamines

NA-SUL 437 is a water soluble rust preventive especially recommended for shortto medium term indoor storage of steel parts. Recommended treat levels are 1% to

5%. It is very tolerant of hard water. At 3% or less, it produces dry to the touchcoatings. It is also recommended for internal aerosol can protection by incorpora-tion into water or alcohol based formulations at 0.25% to 1.0%. NA-SUL 437 willproduce coatings that provide extended protection even in 100% humidity environ-ments.

A water emulsifiable rust preventive based on sodium DNNS, emulsifiers,alkanolamines and waxes

NA-SUL 420 easily forms emulsions by pouring into water with moderate mixing. Itis recommended for short to long term indoor storage. The usual treat levels are1% to 10% depending on the severity of the requirement. Up to 20% can be usedto get moderate salt fog performance. At treat levels below 3%, the resultingprotective films are dry to the touch. If NA-SUL 420 emulsions are spray applied,antifoam may be required.

Modified version of NA-SUL 437

NA-SUL 1019A is similar to NA-SUL 437 with slightly enhanced iron chip testperformance. It is recommended where the aqueous fluid is in contact with thesurface to be protected such as in circulating fluid systems.

Selection Guide for Common Rust Preventive Applications

Many NA-SUL® and King Experimental (KX) additives can be used for various rust and corrosion prevention

applications. The following guide is to help select the best possible additive for some of the more common RPapplications but is by no means all inclusive. As always, King’s technical staff is ready to assist you with yourspecific requirements and can be contacted as shown on the last page.

Indoor storage conditions range from controlled climates to wide seasonal fluctuations intemperature and humidity. The duration of protection required can range from days toyears. The thin protective coatings are generally, but not always, removed prior to use orfurther processing.
