26 NOVEMBER 2017 MATERIALS PERFORMANCE NACE INTERNATIONAL: VOL. 56, NO. 11 'Green' Protection for Metals The BioPouch from Cortec Corp. (St. Paul, Minnesota) represents the company's lat- est advance in environmentally safe cor- rosion protection. The product, aimed at protecting metal parts in a non-ventilated space, is powered by NANO VpCI, the company's newest vapor-phase corrosion inhibitor technolog y from primarily agri- cultural byproducts. The NANO-VpCI is emitted from the pouch and saturates the enclosure via diffusion, filling all void spaces and recessed areas with protective vapor molecules. Molecules from the Bio- Pouch are attracted to and adsorb onto metallic surfaces, resulting in the forma- tion of a protective barrier nano layer. Studies have shown that VpCI molecules provide protection in the presence of cor- rosive species such as chlorides, moisture, and sulfides, and displace them at the metal surface. The vapor-phase inhibiting action protects inaccessible and recessed surfaces. The pouch is quick and easy to use, with no need for special equipment for application. Instead, users simply determine the number of pouches required per unit space. No spraying, wiping, or dipping is required. Tel: 1 800- 426-7832, web site: w w w.cortecvci.com. Topside Transmitters and Loggers Teledyne Cormon, a member of Teledyne Marine (Daytona Beach, Florida) that pro- vides corrosion and erosion monitoring equipment for the oil and gas market, recently introduced an upgrade to its sig- nature CEION and DCU product lines. This new range of topside transmitters and loggers is based on electrical resis- tance measurement principles, with the CEION2 products measuring both metal loss and temperature. An upgrade to the microprocessor and developments on the embedded processing algorithms now provide improved resolution and tempera- ture compensation performance. Data can be acquired from the transmitter and out- put in real-time in direct engineering units without the need for additional post-processing. The transmitter protocol can be configured to allow the connection of multiple sensors on the same power and data network. In addition, the current point-to-point protocol can be configured for full backward compatibility with leg- acy systems. The DCU4 product line is a lower-resolution adaptation for more eco- nomical installations, and also includes a transmitter or logger configuration.

(Lakewood, New Jersey) is a high-f low air filtration unit designed to allow air- craft painting on the hangar f loor without exposing workers to overspray and vola- tile organic compounds. This mobile painting system is rapidly changing the response time to treating and preventing PRODUCT SHOWCASE Epoxy Linings for Railcars Global coatings company AkzoNobel (Amster- dam, The Netherlands) recently released two chemical-resistant linings to help the rail indus- try protect tank and hopper cars from an expanded range of chemical corrosion. The lin- ings are suitable for new railcars or maintaining existing f leets. Owners, original equipment man- ufacturers, and repair shops can now simplify their product range while boosting productivity, throughput, and protection in railcar interiors. The Devchem 253HS product is a high-solids, one- coat epoxy novolac lining that provides strong resistance to a wide range of highly corrosive chemicals and solvents over diverse temperatures and pressures. The Interline 994 is a two-compo- nent, chemical-resistant phenolic epoxy novolac lining that is approved by the U.S. Food and Drug Administration for railcar interiors that carry harsh corrosive liq- uids and oils at high temperatures, including molten sulfur. "These easy-to-use, fast-drying, chemical-resistant linings dramatically increase the level of protection in railcar interiors," says Tim Schaffer, AkzoNobel's key account manager for North American rail.
