Northern Technologies International Corporation (NTIC) develops and markets proprietary, environmentally beneficial products and services in over 65 countries either directly or via a network of subsidiaries, joint ventures, independent distributors, and agents.
NTIC’s primary business is corrosion prevention marketed mainly under the ZERUST brand. NTIC has been selling its proprietary ZERUST products and services to the automotive, electronics, electrical, mechanical, military, and retail consumer markets for over 50 years and, more recently, has also expanded into the oil and gas industry. Additionally, NTIC markets and sells a portfolio of proprietary bio-based and certified compostable (fully biodegradable) polymer resin compounds and finished products under the Natur-Tec brand. These sustainable packaging products are intended to reduce NTIC’s customers’ carbon footprint and provide environmentally sound waste disposal options.
NTIC's ZERUST rust and corrosion inhibiting products include plastic and paper packaging, liquids, coatings, rust removers, cleaners, and diffusers, as well as engineered solutions designed specifically for the oil and gas industry. NTIC also offers worldwide, on-site, technical consulting for rust and corrosion prevention issues. NTIC's technical service consultants work directly with the end users of NTIC's ZERUST rust and corrosion inhibiting products to analyze their specific needs and develop systems to meet their performance requirements. In North America, NTIC sells its ZERUST corrosion prevention solutions through a network of independent distributors and agents supported by a direct sales force.
Internationally, NTIC sells its ZERUST corrosion prevention solutions through its wholly-owned subsidiary in China, NTIC (Shanghai) Co., Ltd. (NTIC China), its wholly-owned subsidiary in India, HNTI Limited (Zerust India), its majority-owned joint venture holding company for NTIC's joint venture investments in the Association of Southeast Asian Nations (ASEAN) region, NTI Asean LLC (NTI Asean), certain majority-owned and wholly-owned subsidiaries, and joint venture arrangements in North America, Europe, and Asia. NTIC also sells products directly to its European joint venture partners through its wholly-owned subsidiary in Germany, NTIC Europe GmbH (NTI Europe).
NTIC markets and sells its ZERUST rust and corrosion prevention solutions to customers in the oil and gas industry in a continuously increasing number of countries either directly, through its subsidiaries, or through its joint venture partners and other strategic partners. The sale of ZERUST corrosion prevention solutions to customers in the oil and gas industry typically involves long sales cycles, often, including multi-year trial periods with each customer and a slow integration process thereafter.
Natur-Tec bio-based and compostable plastics are manufactured using NTIC's patented and/or proprietary technologies and are intended to replace conventional petroleum-based plastics. The Natur-Tec biopolymer resin compound portfolio includes formulations that have been optimized for a variety of applications, including blown-film extrusion, extrusion coating, injection molding, and engineered plastics. These resin compounds are certified to be fully biodegradable in a commercial composting environment and are being used to produce finished products, including can liners, shopping and grocery bags, lawn and leaf bags, branded apparel packaging bags and accessories, and various foodservice items, such as disposable cutlery, drinking straws, food-handling gloves, and coated paper products. In North America, NTIC markets its Natur-Tec resin compounds and finished products primarily through a network of regional and national distributors, as well as independent agents. NTIC continues to see significant opportunities for finished bioplastic products and, therefore, continues to strengthen and expand its North American distribution network for finished Natur-Tec bioplastic products.
Internationally, NTIC sells its Natur-Tec resin compounds and finished products both directly and through its wholly owned subsidiary in China, NTIC (Shanghai) Co., Ltd., and majority-owned subsidiaries in India, Natur-Tec India Private Limited, and Sri Lanka, Natur Tec Lanka (Pvt) Ltd, and through distributors and certain joint ventures.
NTIC's Subsidiaries and Joint Venture Network
NTIC has ownership interests in 11 operating subsidiaries in North America, South America, Europe, and Asia.
NTIC participates in 15 active joint venture arrangements in North America, Europe, and Asia. Each of these joint ventures generally manufactures and markets products in the geographic territory to which it is assigned. While most of NTIC's joint ventures exclusively sell rust and corrosion inhibiting products, some of the subsidiaries also sell NTIC’s Natur-Tec resin compounds and finished goods.
Products
NTIC derives revenues directly and/or indirectly through its subsidiaries and joint ventures from two reportable business segments based on products sold, customer base, and distribution center: ZERUST Corrosion Prevention Solutions and Natur-Tec Resin Compounds and Finished Products.
ZERUST Corrosion Prevention Solutions
In the year ended August 31, 2024 (fiscal 2024), 74.2% of NTIC's consolidated net sales were derived from developing, manufacturing and marketing ZERUST rust and corrosion inhibiting products and services. NTIC's ZERUST corrosion prevention solutions include plastic and paper packaging, powders, liquids, coatings, rust removers, cleaners, diffusers, and engineered solutions for the oil and gas industry, as well as technical corrosion management and consulting services.
Plastic and Paper Packaging
NTIC's ZERUST packaging products contain proprietary chemical formulations that continuously release an invisible, odorless and non-toxic vapor that forms a passivating layer on any metal surfaces it comes in contact with and thereby inhibits rust and corrosion. The corrosion inhibiting protection is maintained only as long as the metal products to be protected remain enclosed within the ZERUST packaging. Electron scanning shows that once metal products are removed from the ZERUST packaging, the ZERUST protective layer dissipates from the contents' surfaces within two hours, leaving a clean, dry, and corrosion-free metal component. This mechanism of corrosion protection enables NTIC's customers to easily package metal objects for rust-free shipment and/or long-term storage. Furthermore, by eliminating costly greasing and degreasing processes and/or significantly reducing the use of certain coatings to inhibit corrosion, NTIC's ZERUST corrosion prevention solutions provide customers significant savings as compared to traditional methods of corrosion prevention in terms of labor, material, and capital expenditures for equipment to apply, remove, and dispose of oils and greases, as well as environmental, health and safety benefits provided by not having to handle and work with hazardous chemicals.
NTIC was the first in the world to develop the means of infusing volatile corrosion inhibiting chemical compounds (VCIs) into polyethylene and polypropylene resins. Combining ZERUST chemical compounds with polyethylene and polypropylene resins permitted NTIC to introduce a line of plastic packaging products in the form of low and high-density polyethylene bags and shroud film, including stretch, shrink, skin, and bubble cushioning film, thereby giving customers the ability to ship and store ferrous, nonferrous, and mixed-metal products in a clean, dry, and corrosion-free condition. In addition to plastic packaging, NTIC has developed VCI compounds to imbue kraft paper, corrugated cardboard, solid fiber, and chipboard packaging materials with corrosion protection properties. NTIC's ZERUST plastic and paper packaging products come in various thicknesses, strength enhancements, protection types, shapes, and sizes. This product line also includes items, such as ZERUST gun cases, car covers, and tool-drawer liners, which are targeted at retail consumers.
Liquids and Coatings
NTIC's corrosion prevention solutions include a line of metal surface treatment liquids and coatings, which are oil, water, or bio-solvent based; and are marketed under brand names, including Axxatec, Axxanol, and Z-Maxx. These liquids and coatings provide powerful protection in aggressively corrosive environments, such as salt air, high humidity, and/or high temperatures. Products are formulated for most metal types and protection levels. For exceptionally harsh environments, customers may choose to use a combination of NTIC's liquids and coatings with ZERUST plastic and/or paper products to achieve robust corrosion protection during manufacturing, shipping, and warehousing stages.
Rust Removers and Cleaners
NTIC also sells rust removal and cleaning products, under the Axxaclean brand name, designed to restore rusty parts to a usable condition without the use of labor-intensive, abrasive cleaners that damage surfaces and commonly fail to remove rust from complex metal surfaces, like the teeth of small gears.
Diffusers
NTIC's corrosion prevention solutions include a line of corrosion inhibiting vapor diffusers, such as ZERUST ActivPak, ZERUST ICT Vapor Capsules, ZERUST ICT Plastabs, ZERUST ICT Cor-Tabs, ZERUST ICT Pipe Strip, and ZERUST ICT Tube Strip. These diffusers are designed to protect metals within enclosures, like switch gearboxes and electronics cabinets, or can be used as extra protection when added to ZERUST packaging products. Diffusers work by permeating the interior air of an enclosure with an invisible and odorless corrosion inhibiting vapor that settles as a protective layer on all metal surfaces that are within the range of a specific 'radius of protection' for a period of one or two years depending on the product model. This invisible and dry protective layer revaporizes and dissipates into the air upon removal of a diffuser from an enclosure, leaving all surfaces clean, dry, residue-free, and corrosion-free.
Z-CIS Technical Services
As an on-going effort to help NTIC's customers improve and control their corrosion management processes, NTIC markets and offers unique corrosion management and consulting services to target customers. This ZERUST corrosion inhibition system (known as Z-CIS) leverages NTIC's global network to dispatch highly-trained technical service engineers to customer sites to solve complex corrosion problems. Several major automotive companies and their automotive parts suppliers have used NTIC's Z-CIS system.
ZERUST Corrosion Prevention Solutions Designed Specifically for the Oil and Gas Industry
NTIC has developed proprietary engineered corrosion inhibiting solutions specifically to mitigate the types of corrosion that commonly form on the capital assets used in the petroleum and chemical process industries and has targeted the sale of these ZERUST corrosion solutions to potential customers in the oil and gas industry.
NTIC anticipates that its sales of ZERUST products and services into the oil and gas industry will continue to remain subject to significant volatility, specifically due to economic factors, such as potential crude oil price changes and global supply/demand churn.
NTIC’s rust and corrosion inhibiting products for the oil and gas industry include ZERUST Flange Savers, ZERUST Zif Tape, ZERUST ReCAST- Soil Side Bottoms (SSB) solutions, and ZERUST chemicals, including Zerion powders and gels, in addition to many of the standard industrial ZERUST rust and corrosion inhibiting products.
ZERUST Flange Savers are specially designed covers that have been impregnated with a proprietary ZERUST inhibitor formulation to provide corrosion protection for flanges, valves, and welded joints. Oil and gas pipeline segments are connected by flanges and welded joints of varying sizes, designs, and materials. These connection points often corrode under aggressive industrial environments and harsh operating conditions, thereby causing costly maintenance, operational, and safety problems. ZERUST Flange Savers are available in various sizes to accommodate different pipe diameters, pressure ratings, and international standards for pipeline valves and flanges.
ZERUST ReCAST-SSB solutions protect the Soil Side Bottoms (SSB) of aboveground storage tanks through a variety of unique and highly effective delivery systems designed by the Zerust Oil & Gas team to deliver proprietary Zerion FVS corrosion inhibitor to spaces under tank bottoms that are susceptible to significant corrosion. Tank bottoms are typically made of steel plates, which are in direct contact with a foundation surface that may be concrete, sand/soil, or asphalt/bitumen. It is typically not possible to protect this underside surface with traditional coatings. Cathodic protection (CP) systems can only provide partial protection, but also have significant limitations that cause failures well ahead of the expected service life of a tank. The ZERUST solutions provide effective protection even to areas that cannot be addressed with CP. These are engineered solutions where each system is tailored to a customer’s requirements depending on factors, including the tank foundation design, specific environmental conditions, and tank diameter.
ZERUST Zerion powder-based inhibitor solutions include the following:
Zerion FVS is a unique inhibitor blend that is used in both the SSB Solutions and in internal pipeline protection. This best-in-class product has been successfully deployed at multiple client sites in North and South America, Europe, the Middle East, India, as well as other parts of Asia.
Zerion FAN-5 is a lower cost inhibitor that is very effective at protecting metals upon contact. It can be used to treat large volumes of water that may be used for hydrotesting. In combination with Zerion FVS, it offers a more complete solution for the protection of pipelines.
AutoFog is a revolutionary product that allows for the quick VCI saturation of large volume spaces without the need for mechanical ‘fogging’ equipment. This rapid self-diffusing capability is designed for sealed void spaces, protection of large/complex assets like heat exchangers, and heater-treaters.
Natur-Tec Resin Compounds and Finished Products
This segment engages in broad range of bioplastic packaging solutions, including bio-based and certified compostable (fully biodegradable) polymer resin compounds, and finished products under the Natur-Tec brand.
Resin Compounds
Natur-Tec resin compounds are produced by blending commonly available base resins, such as Ecoflex from BASF, Ingeo PLA from NatureWorks LLC, and Luminy from Total-Corbion with organic and inorganic fillers and proprietary polymer modifiers and compatibilizers using NTIC’s proprietary and patented ReX Process. In this process, biodegradable polymers, natural polymers made from renewable, plant-biomass resources, and organic and inorganic materials are reactively blended in the presence of proprietary compatibilizers and polymer modifiers to produce bio-based and/or compostable polymer resin formulations that exhibit unique and stable morphology. Natur-Tec resin compounds are engineered for high performance, ease of processing, and reduced cost compared to most other bio-plastic materials and can be processed by converters using conventional plastic manufacturing processes and equipment.
Natur-Tec resin compounds are sold in several grades tailored for a variety of applications, such as blown-film extrusion, profile extrusion, thermoforming, extrusion coating, and injection molding.
Natur-Tec flexible film resin compounds are fully commercially compostable and meet the requirements of international standards for compostable plastics, such as ASTM (American Society for Testing and Materials) D6400 (U.S.), EN 13432 (European standards for products and services by European Committee for Standardization), and ISO (International Organization for Standardization) 17088, and are certified as 100% compostable by organizations including the BPI (Biodegradable Products Institute) in the United States and TÜV Austria in Europe. Natur-Tec film resin compounds can be used to produce film for applications, such as bags, including compost bags, lawn and leaf bags, carry-out bags, agricultural film, and consumer and industrial packaging. Natur-Tec film resin compounds are also used to produce bags and covers for branded apparel packaging and to manufacture specialty foodservice items, such as compostable drinking straws, thermoformed lids and disposable food-handling gloves.
The Natur-Tec compostable extrusion coating resin compounds are bio-based and biodegradable and are designed to replace conventional plastic materials for extrusion coating applications. Natur-Tec extrusion coating resin compounds are manufactured using sustainable and renewable resources, per the ASTM D6866 standard, which allows companies and consumers the opportunity to reduce or neutralize their carbon footprint and are designed to meet the requirements of international standards for compostable plastics, such as ASTM D6400. Natur-Tec extrusion coating resin compounds provide good adhesion to paper, an excellent print surface, and good heat seal strength and the coating material is suitable for food contact applications, including both hot and cold applications. Natur-Tec extrusion coating resin compounds can be used for coating paper and paperboards for the manufacture of disposable cups, plates, and other foodservice items.
The Natur-Tec compostable injection molding resin compounds are bio-based and compostable and are designed to replace conventional plastic materials for injection molded plastic applications. Natur-Tec compostable injection molding resin compounds are manufactured using sustainable and renewable resources, per the ASTM D6866 standard, and are designed to meet the requirements of international standards for compostable plastics, such as ASTM D6400 and EN 13432. Natur-Tec compostable injection molding resin compounds can be used for injection molded plastic applications, such as cutlery, pens, hangers, containers, and packaging. Natur-Tec bio-based injection molding resin compounds are made with at least 90% bio-based/renewable resource-based materials, per the ASTM D6866 standard, and are meant to enhance sustainability by replacing petroleum-based plastics. Natur-Tec bio-based injection molding resin compounds exhibit the same properties as conventional plastic materials and can be used in applications, such as automotive components, consumer goods, electronics, medical products, furniture, and packaging.
Finished Products
Natur-Tec finished products include totally biodegradable and compostable trash bags, agricultural film, and other single-use disposable products, such as food and consumer goods packaging marketed under the Natur-Bag brand. The Natur-Bag product line offers 15 different compostable trash bag sizes, from 3-gallon to 96-gallon, as well as shopper bags, produce bags and gloves. The bags are available in various SKU configurations, including retail packs that are sold to the consumer either through retail outlets or through online stores and industrial case packs that are sold to commercial and industrial customers primarily through national and regional wholesalers and distributors. The Natur-Bag products are manufactured from the Natur-Tec flexible film resin compounds and thus are fully biodegradable and compostable. These products are certified fully commercially compostable and carry the BPI Compostable logo in the United States and the TÜV Austria OK Compost logo in Europe. Furthermore, these products were also independently tested and approved for use in organic waste diversion systems by Cedar Grove, one of the largest compost operators in the United States.
