Overview
Hexion is a Columbus, Ohio-based specialty chemicals company whose principal activities center on thermoset resins, resin technologies, and chemical products used in industrial manufacturing. Its portfolio serves markets in which resins act as binders, coatings, adhesives, matrices, intermediates, or performance-enhancing components. Applications associated with the company include abrasives, adhesives, coatings, composites, engineered wood, electrical and electronic materials, friction materials, furniture, molding compounds, oilfield products, refractories, and agricultural and industrial chemical formulations. The company was created in 2005 through the combination of several established chemical businesses: Borden Chemicals, Resolution Performance Products, Resolution Specialty Materials, and Bakelite AG. The formation also included the acquisition of Pacific Epoxy Products. This heritage gave Hexion a broad base in epoxy, phenolic, formaldehyde-related, and other thermoset resin technologies rather than a single-product identity. Its development therefore reflects the consolidation of multiple resin businesses and product families under one specialty-chemicals brand. Hexion’s activities have commonly been organized around two broad operating areas. The Epoxy, Phenolic and Coating Resins division supplies resin systems and related technologies for coatings, composites, adhesives, electrical applications, abrasives, molding materials, and other industrial uses. The Forest Products division supplies resin and binder technologies used in engineered wood products, including oriented strand board, particleboard, fiberboard, plywood, and laminated veneer lumber. These businesses connect Hexion to both downstream manufactured products and large-scale construction and building-material supply chains. The company’s corporate structure changed after its creation. In 2010, the parent holding companies of Momentive Performance Materials and Hexion Specialty Chemicals were combined into Momentive Performance Materials Holdings LLC. In 2015, the combined company adopted the Hexion name. The brand has consequently been associated with both Hexion and Momentive in different periods, although its operating identity has remained focused on specialty materials and resin technologies. Hexion has also adjusted its asset portfolio through divestment and business-portfolio decisions. In 2020, it announced an agreement to sell its manufacturing site in Yumbo, Colombia, to a joint venture led by Master Paints & Chemical Corporation. In 2022, Westlake completed the acquisition of Hexion’s epoxy division. These transactions indicate a strategic emphasis on reshaping the company’s manufacturing footprint and business mix. Hexion remains identified with thermoset resins, phenolic technologies, coating resins, and forest-products binders, while specific assets and divisions may change through portfolio transactions.
History
Hexion was formed in 2005 as a consolidated specialty-chemicals company built from several established resin and chemical businesses. The founding combination brought together Borden Chemicals, Resolution Performance Products, Resolution Specialty Materials, and Bakelite AG. Hexion also acquired Pacific Epoxy Products at the time of its formation. Rather than representing the launch of a wholly new chemical technology, the transaction assembled complementary businesses with existing capabilities in thermoset resins, epoxy materials, phenolic chemistry, coatings, and related industrial applications. The resulting company developed a broad product and application portfolio. Its resin technologies were used in adhesives, coatings, composites, abrasives, electrical and electronic materials, friction products, molding compounds, refractories, and other industrial formulations. A separate forest-products business supplied binders for engineered wood products such as oriented strand board, particleboard, fiberboard, plywood, and laminated veneer lumber. This combination gave Hexion exposure to both specialty-materials markets and construction-related wood-product manufacturing. A major corporate restructuring occurred in 2010, when the parent holding companies of Momentive Performance Materials and Hexion Specialty Chemicals were merged to create Momentive Performance Materials Holdings LLC. The relationship between the Hexion and Momentive names subsequently reflected the corporate history of the combined group. In 2015, the combined company changed its name to Hexion Inc., establishing Hexion as the principal corporate identity. The company later made portfolio and asset changes. In February 2020, Hexion announced a definitive agreement to sell its manufacturing site in Yumbo, Colombia, to a joint venture led by Master Paints & Chemical Corporation. The transaction concerned a manufacturing location rather than the entire Hexion business. In 2022, Westlake completed the acquisition of Hexion’s epoxy division. That deal transferred a significant epoxy-focused business area to Westlake while Hexion continued to be associated with other resin, coating, phenolic, and forest-products activities. Hexion’s historical identity is therefore defined by consolidation, specialization, and portfolio management. Its business has been organized around resin technologies that are incorporated into customers’ products and processes rather than generally sold as consumer-facing finished goods. The company’s principal industrial role is to provide formulation chemistry and binding systems for durable materials, coatings, engineered wood, composites, adhesives, and other applications. Because its products are used across many manufacturing sectors, Hexion is best understood as a business-to-business specialty-chemicals brand whose importance lies in enabling downstream performance and production.

Thermoset resins
Epoxy resins
Epoxy resin technologies are used as binders, matrix materials, coatings, and adhesive components. Within Hexion’s historical portfolio, epoxy products served applications including composites, electrical and electronic materials, coatings, adhesives, civil engineering, oilfield uses, and other industrial formulations. The epoxy division was acquired by Westlake, with completion reported in 2022.
Thermoset resins
Phenolic resins
Phenolic resin systems provide heat-resistant and durable binding performance for industrial materials. Hexion’s phenolic technologies have been associated with applications such as abrasives, friction materials, refractories, molding compounds, insulation and foams, engineered wood, and other manufactured products requiring a cured thermoset binder.
Coating materials
Coating resins
Coating resins are formulated for protective, decorative, and performance-oriented surface treatments. Hexion identifies coating resins as part of its resin business, serving industrial coating formulations and related applications where adhesion, durability, chemical resistance, or processing performance is required.
Engineered-wood chemicals
Forest-products binders
Hexion’s Forest Products division supplies resin and binder technologies used to manufacture engineered wood. Relevant product applications include oriented strand board, particleboard, fiberboard, plywood, and laminated veneer lumber. These binders help convert wood particles, strands, fibers, or veneers into structural and furnishing materials.
