Bisphenol A-Based Liquid Epoxy Resin (BPA-LER)

US chlor-alkali and VCM producer (NYSE: OLN, HQ Stamford CT; ~$6B revenue); the largest US chlorine producer and a major feedstock supplier to the PVC resin industry. Olin does not directly produce PVC resin but produces the chlorine and vinyl chloride monomer (VCM) that PVC resin manufacturers (Westlake, Shintech, OxyChem) depend on. Olin's chlor-alkali operations in Freeport TX (the largest chlorine plant in the US), McIntosh AL, Niagara Falls NY, and other sites collectively make Olin the critical upstream enabler of the US PVC supply chain. Olin also owns Winchester ammunition — meaning the same company that produces the chlorine input for PVC pipe also manufactures rifle and shotgun ammunition, a striking dual-use combination under one NYSE ticker. Olin's chlorine pricing directly sets the economics for US PVC resin production.

US specialty chemicals company (Columbus, Ohio). Its UV Coatings (Shanghai) subsidiary — founded as Borden UV (Shanghai) 2004, renamed Hexion UV Coatings (Shanghai) — produces Klearshield (primary) and Spectrashield (secondary) fiber optic acrylate coatings for the Chinese export market. Customers confirmed: OFS Fitel (Furukawa subsidiary, Avon CT) and Prysmian. Hexion Inc. was acquired by Allnex (~2023-2024), so this fiber optic coating business is now under Allnex's ownership. ITC case: DSM Desotech filed 337-TA-1031 in 2016 alleging Hexion/Momentive UV Coatings Shanghai infringed Kevlar coating patents; ITC ruled no violation (2018), confirming Hexion's process is independently valid.

American specialty chemicals company (NYSE: HUN, HQ The Woodlands TX; ~$6B revenue); Advanced Materials division produces Araldite epoxy resins for industrial coatings, aerospace composites, wind turbine blades, and construction applications. Huntsman is simultaneously the world's 3rd-largest MDI polyurethane producer (for OSB and insulation) AND a major epoxy resin supplier for protective coatings and aerospace composites. The same Huntsman that supplies MDI for OSB building panels also makes the Araldite epoxy resin in marine coatings on container ships and in aerospace composite aircraft structures. Huntsman was founded by Jon Huntsman Sr. (Utah industrialist; US Ambassador to Russia under George W. Bush), who was also the subject of a famous 1993 leveraged buyout thriller that influenced US private equity law; the company's founder died in 2018. Huntsman Corporation is controlled by the Huntsman family.

Taiwanese plastics and chemicals company (TSE: 1303, HQ Xinzhuang, New Taipei City; ~NT$200B revenue; subsidiary of Formosa Plastics Group); world's largest producer of bisphenol A (BPA) — the key raw material for BPA-based epoxy resins and polycarbonate. Nan Ya Plastics produces BPA at its Mailiao and Linkou facilities using acetone and phenol feedstocks, then converts some BPA into downstream epoxy resins for coatings. Formosa Plastics Group (Taiwan's largest industrial conglomerate, founded by Y.C. Wang — the legendary Taiwanese plastics entrepreneur who built a multibillion-dollar empire from PVC) is both the world's largest PVC producer and the world's largest BPA producer through Nan Ya Plastics. The same BPA that is the centerpiece of endocrine-disruption concerns (leaching from polycarbonate bottles, can linings) and the same BPA that goes into industrial epoxy protective coatings for marine and industrial use comes from Nan Ya Plastics' Taiwanese facilities. Wang's empire — which spans Formosa Plastics (PVC), Formosa Chemicals & Fibre (fiber and chemicals), Nan Ya Plastics (BPA, PCB substrates), and Formosa Petrochemical (refining) — is one of the most vertically integrated petrochemical conglomerates in Asia.
