NA-SUL®Rust Preventive Additives

SPECIALTY CHEMICALS®

A Guide for Using

NA-SUL® Rust and Corrosion Inhibitors have delivered superior rust and corrosion protection worldwide since 1952. The NA-SUL

trademark is short for naphthalene sulfonate. Dinonylnaphthalene sulfonates o�er uniquely e�ective chemistry

because of their polarity combined with excellent solubility in a wide range of carrier �uids. Combining this chemistry with

other synergistic polar compounds produces rust and corrosion preventive additives with unsurpassed e�ectiveness.

The additives described in this brochure can be used to solve most common rust and corrosion problems.

They are typically e�ective at a treat rate of 1/2 or less compared with competitive rust and corrosion preventive additives.

Classi�cation of Rust Preventive Additives

Oil-Based formulations consist of the rust preventive additive in oil alone. For this purpose oil includes mineral oil, vegetable oils, synthetic oils such as polyalphaole�n (PAO) and alkylated naphthalene, esters, polyalkylene glycols and many more. These formulations typically provide an oily coating with lubricity and low VOC content.

Oil-Solvent formulations consist of the rust preventive additive, oil and a volatile solvent. These less oily formulations are used to provide increased rust protection, improved penetration into crevices, or dewatering properties where the rust preventive displaces water from wet metal parts and leaves a protective coating. The amount of rust preventive additive left after the solvent evaporates in the coating is proportionally greater, thus improving protection.

Rust preventives may be classi�ed a number of ways based on their performance requirements. NA-SUL additives are available to meet a broad range of applications. This guide is to assist in the selection of the appropriate NA-SUL rust preventive additive.

NA-SUL rust and corrosion inhibitors exhibit superior salt fog performance compared to other sulfonate chemistries. Dinonylnaphthalene sulfonates are e�ective in a wide range of applications from general and indoor storage to harsh exterior applications. NA-SUL corrosion inhibitors are e�ective on steel, galvanized steel, aluminum and various other metals.

NA-SUL Performance vs. Other Sulfonates

Water-Based formulations are either solutions or emulsions. Solutions rely on polar chemical activity alone for metal protection. Emulsions can add oil or waxes along with polar activity to give better rust prevention. In these systems, water is substituted for organic solvents resulting in greatly reduced VOC. This gives lower �ammability, lower worker exposure to solvents and easier regulatory compliance for VOC’s. The disadvantage of water-based formulations is slower drying time.

NA-SUL CA-1082 is a highly e�ective liquid rust and corrosion inhibitor. It outperforms most additive systems containing wax or polymers in salt fog testing. It has excellent solubility in base �uids such as highly processed para�nic oils and PAO, although rust prevention is best in naphthenic oils or less highly re�ned para�nic oils and solvents. NA-SUL CA-1082 also functions as a dispersant to keep waxes in suspension allowing stable thixotropic formulations for extended rust prevention.

It resists gelling when exposed to water and therefore can be used in high moisture applications such as rust preventives applied to wet parts. Contamination with alkaline metalworking �uids may cause gelling. Compatibility with other process chemicals should also be veri�ed prior to use.

Salt Fog “hours to failure” is de�ned as rust extending more than 1.5 cm from the top edge or more than 0.5 cm from either side edge. This is used by King Industries and is not in the ASTM B 117 Practice.

P = polished test surface M = matte test surface

The solubility of additives in speci�c oils and solvents should always be con�rmed. Compatibility with likely contaminants of bulk rust preventives should be veri�ed prior to use.
