22 OCTOBER 2017 MATERIALS PERFORMANCE NACE INTERNATIONAL: VOL. 56, NO. 10 Scale Remover Certified as Bio-Based Product The EcoClean biodegradable scale and rust remover from Cortec Corp. (St. Paul, Minnesota) is now a certified bio-based product from the U.S. Department of Agri- culture (USDA) (Washington, DC). As such, the product is certified by a third party to contain 100% bio-based content. The product also exceeds minimum USDA requirements for metal cleaners and cor- rosion removers qualified for federal pur- chasing under the USDA's BioPreferred program. In addition to the bio-based qualifications, the remover is effective and easy to use. It is a fast-acting product for dissolving heav y scale, corrosion, and naturally occurring oxides off metals. Creating clean surfaces is important for improving f low in scale-obstructed water or drainage pipes and heat-transfer effi- ciency on heat exchanger equipment. Powerful corrosion inhibitors contained in the scale remover also protect treated metals from f lash rust. The remover is safe to use with multiple metals, including iron, carbon steel, stainless steel, copper, aluminum, magnesium, and various alloys, and it is available in an easy-to- ship powder form and a ready-to-use liq- uid form.

(Gardco) (Pompano Beach, Florida) are now available for measuring water- soluble salts and corrosion products on blast-cleaned steel. Soluble salt com- pounds are almost colorless and are local- ized at the lowest point of the rust pits. If they are not removed prior to painting, chemical reactions can result in blister formation and accumulations of rust that destroy the adhesion between the sub- strate and the applied protective coating. The latex and chloride-free high-adhesion patches use an elastomer so that the syringe does not pierce, and are suitable for testing on corroded or coarse-grade blasted steel. Each patch should be used within 12 months from the date of pur- chase. Tel: 1 888-406-6506, web site: w w w.gardco.com. Additive Processes Use Powder Metallurgy Heat treatment and specialist thermal processing services provider Bodycote (Macclesfield, United Kingdom) intro- duced a new suite of Powdermet technolo- gies, a group of additive manufacturing processes that use powder metallurg y to produce components. The technologies incorporate new, patent-pending tech- niques that combine three-dimensional (3D) printing with well-established net shape and near net shape techniques. This new technolog y dramatically reduces the manufacturing time and production cost of a part compared to producing the same part using 3D printing alone. The technol- og y ensures complete powder consolida- tion, achieves structural homogeneity, and eliminates internal porosity and unconsolidated powder f laws. With this process, the need for brazing or welding parts together to form larger structures is eliminated. Instead, the finished article can be produced as one seamless compo- PRODUCT SHOWCASE Water-Based Aliphatic Urethane Floor Coatings Sherwin-Williams Protective & Marine Coatings (Bolton, United Kingdom) is now offering water-based f loor coatings with no hot-tire pickup and improved hot-tire staining resistance. The AquArmor W BU coat- ings, which work on both f loors and walls, deliver appli- cation and aesthetic characteristics that rival solvent- based products—with the added benefit of lower volatile organic compounds. Wet edge application properties help to minimize the potential for roller lap marks, ensuring a consistent gloss and satin sheen for the line's two available fin- ishes. After curing, the coatings also prevent tires from leaving excessive, perma- nent stains. The line provides superior chemical-resistance properties, helping to enhance the aesthetics of automotive dealership showrooms, aircraft hangars, food and beverage facilities, warehouses, pharmaceutical processing facilities, and more. Long recoating windows help with project scheduling while ensuring an increased bond between coating layers. The coatings also have a short dry time, permitting foot traffic at 18 h, light traffic at 24 h, and wheeled traffic at 48 h— enabling fast returns to service. They are available in multiple finishes and custom colors. Tel: 1 800-524-5979, web site: w w w.protective.sherwin-williams.com.
