Market overview

Bisphenol A diglycidyl ether (BADGE, CAS 1675-54-3) is the main component of standard liquid epoxy resin, made from bisphenol A and epichlorohydrin. It is the base of epoxy coatings, composites (including wind blades), adhesives, electronics laminates and civil engineering. Olin is a major producer and Huntsman is a major epoxy formulator, so the merger joins the two ends of this chain. Bisphenol A regulation in food-contact uses is a separate pressure on demand.

The question this report answers
How big is liquid epoxy resin within the epoxy market, and who has cost advantage?

Market Krystal preliminary estimate (2025)
On MnM’s USD 14.8 bn epoxy market (2025), liquid epoxy resin at 50-70% gives USD 7-11 bn. Confidence grade C: no reliable published figure; range built from the stated assumptions and narrowed in the full report.

Market dynamics
– Demand: coatings, composites (wind), electronics, adhesives
– Supply: Westlake, Olin, Huntsman, Nan Ya, Kukdo, Chinese producers
– Price and margin: BPA and ECH costs
– Regulation: BPA restrictions in EU food contact

Key figures at a glance (third-party, cited)
– Epoxy resin market: USD 14.77 bn (2025) to USD 20.31 bn by 2030 at 6.6% CAGR (MarketsandMarkets)
– Key players named include Sinopec, Westlake Epoxy, Olin, Huntsman, Nan Ya, Kukdo, Aditya Birla, Mitsubishi Chemical and BASF (MarketsandMarkets)

Recent developments among key stakeholders
– Jun 2026: Huntsman and Olin signed an all-stock merger of equals (OlinHuntsman, about USD 12.5 bn pro forma revenue, >USD 400 mn synergies); shareholders approved it and closing is expected in 1H 2027 (ChemXplore)

What this means for the market
The merger combines two large positions in this value chain. Integration teams, competitors and customers will reassess capacity, pricing and supplier concentration through the 2027 closing.

How published estimates compare
Epoxy resin totals include solid, specialty and formulated systems. Market Krystal sizes standard liquid epoxy (BADGE) in tonnes and value and models the vertical overlap created by OlinHuntsman.

Strategic scenarios to 2047
– Base: demand follows GDP, construction and population; China and the Middle East add capacity while Europe rationalises on energy costs.
– Constrained supply: energy shocks, carbon prices and closures in Europe tighten regional supply and widen price spreads between regions.
– Technology transition: low-carbon routes (green hydrogen, electrified crackers, bio-feedstocks, CO2 capture) change cost curves and favour early movers.
The swing factor for Bisphenol A diglycidyl ether (BADGE, liquid epoxy resin) is wind and electronics composites demand. Signposts: European closure announcements, EU CBAM scope, Chinese capacity additions, energy prices.

What this report delivers
Annual volume (tonnes) and value (USD) for 2026-2035, segmented by product: standard liquid epoxy, solid epoxy, low-chlorine electronics grades; application: coatings, composites and wind, adhesives, electrical laminates, civil engineering; region: China, Europe, North America, Korea and Taiwan, India. Each segment is backed by a producer capacity table, price benchmarks for 2020-2025 by grade and region, trade-flow analysis and a supplier risk map. Companies assessed include Olin, Westlake Epoxy, Nan Ya Plastics, Kukdo Chemical, Aditya Birla Chemicals, Huntsman (Advanced Materials, formulator). The 2036-2047 outlook uses three explicit scenarios (base, constrained supply and technology transition) rather than a single extrapolated curve.

Who uses this report
Producers, large buyers, commodity traders and chemical-sector investors.

Why our approach is evidence-based
Most CAS-level market listings publish a single number with no audit trail, and we regularly find figures that contradict their own growth rates or exceed the size of the market they sit inside. Market Krystal works the other way round. We start from physical evidence: plant capacities, production and trade data, company disclosures, regulatory texts and price records. We build volume and price separately and only then compute value. Every third-party figure is cited, every Market Krystal estimate is labelled with its method and a confidence grade, and conflicts between sources are shown rather than hidden. Confidence grades: A = two or more independent sources agree, or government or company data; B = one published estimate checked against volumes or prices; C = no reliable published figure, so the range is built from stated assumptions and narrowed in the full report.

Methodology and delivery
Prepared by the Market Krystal Chemicals Research Team. Each report is built around the buyer’s question: after purchase, a short scope confirmation fixes the priority regions, companies and applications, and the report is delivered within 5-7 business days with the Excel model behind every estimate, so buyers can audit and change the assumptions.

The purchased delivery includes the PDF report, Excel datasets and customization around the buyer’s priority region, company set, application or commercial question.
