1 SPECIALTY CHEMICALS A Guide for Using NA-SUL Rust Preventive Additives

2 NA-SUL Rust and Corrosion Inhibitors have delivered superior rust and corrosion protection worldwide since The NA-SUL trademark is short for naphthalene sulfonate. Dinonylnaphthalene sulfonates offer uniquely effective chemistry because of their polarity combined with excellent solubility in a wide range of carrier fluids. Combining this chemistry with other synergistic polar compounds produces rust and corrosion preventive additives with unsurpassed effectiveness. The additives described in this brochure can be used to solve most common rust and corrosion problems. They are typically effective at a treat rate of 1/2 or less compared with competitive rust and corrosion preventive additives.

3 NA-SUL Performance vs. Other Sulfonates NA-SUL rust and corrosion inhibitors exhibit superior salt fog performance compared to other sulfonate chemistries. Dinonylnaphthalene sulfonates are effective in a wide range of applications from general and indoor storage to harsh exterior applications. NA-SUL corrosion inhibitors are effective on steel, galvanized steel, aluminum and various other metals. 24 Hours Exposure Comparative Calcium Sulfonate Performance in 90% Group I, ISO VG 32 Paraffinic Oil NA-SUL - Typical Performance Polished Matte Polished Matte 10% Calcium Petroleum Sulfonate/carboxylate 10% Calcium Dinonylnaphthalene Sulfonate/carboxylate Classification of Rust Preventive Additives Rust preventives may be classified 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. Pg Pg. 2-7 Aqueous Non-Aqueous 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 polyalphaolefin (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. 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 flammability, lower worker exposure to solvents and easier regulatory compliance for VOC s. The disadvantage of water-based formulations is slower drying time. 1

9 NA-SUL CA-1082 NA-SUL CA-1082 is a highly effective liquid rust and corrosion inhibitor. It outperforms most additive systems containing wax or polymers in salt fog testing. It has excellent solubility in base fluids such as highly processed paraffinic oils and PAO, although rust prevention is best in naphthenic oils or less highly refined paraffinic 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 fluids may cause gelling. Compatibility with other process chemicals should also be verified prior to use.

The chamber is maintained at 35 C with a continuous fog of a 5% NaCl solution. General Comments The solubility of additives in specific oils and solvents should always be confirmed. Compatibility with likely contaminants of bulk rust preventives should be verified prior to use. hours to failure is defined 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 There are Product Data Sheets and Technical Reports for these and other products with additional information and test results available on our website and through our technical service department. 12
