Key Players
Competitive Landscape
As per the analysis from FMI, suppliers in the blade infusion resins market compete on wind-specific formulas, large-blade process support and proven recyclable options. Integrated Epoxy Producers with Wind Formulations win on scale and dedicated wind product lines.
Another cohort of key players operating as Formulated-System and Process-Support Specialists eye for consolidation in the market through process know-how. Recyclable Chemistry and Curing-Agent Innovators lead in the market at expertise where chemistry itself is the selling point. In every group, buyers judge the supplier on factory results, not on data sheet claims.
Supply and technology are both moving. Olin is closing its Brazilian epoxy plant and has added a German supply agreement. Westlake Epoxy offers certified mass-balance epoxy in the USA and Europe. Besides this, recyclable epoxy from Swancor and Aditya Birla has reached commercial and prototype blades. Analyst suggests that suppliers with proven stable process window and reliable local stock will take the next round of platform approvals and inch towards consolidation.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| Swancor | August 2025: recyclable epoxy in 108-meter blades for RWE’s Sofia | OEMs and developers need end-of-life solutions for blades. | Recyclable thermosets are moving into serial offshore blades. | Proven large-blade references can support new OEM qualifications. |
| Aditya Birla | April 2026: Recyclamine adopted for Leitwind LS20.X_MK2 blade | Turbine makers are seeking recyclable blade materials. | Recyclable epoxy is being built into resin and bonding paste together. | Rollout to larger Leitwind platforms can add volume if tests succeed. |
| Gurit | April 2026: Wind Materials sales up on epoxy formulated products | Western OEMs are raising blade output. | Formulated epoxy systems are gaining share of supplier revenue. | Suppliers with OEM approvals can capture recovering demand. |
| Olin | January 2026: Guarujá plant closure and Stade supply agreement | Buyers need secure regional epoxy supply. | Producers are restructuring epoxy footprints for cost. | Continuity planning can become a selling point in qualification. |
| Westlake Epoxy | May 2026: Deer Park ISCC PLUS certification | Blade customers are setting lower-carbon material targets. | Mass-balance epoxy is spreading from Europe to the USA. | Certified drop-in resins can meet targets without requalification of chemistry. |

Who leads the blade infusion resins market?
No single supplier leads every part of the blade infusion resins market. Westlake Epoxy and Olin Epoxy lead in base epoxy, with wind-specific product lines. Gurit and Sika lead in formulated systems backed by process support. Swancor and Aditya Birla Chemicals lead in recyclable epoxy for commercial and prototype blades.
Which companies make their own epoxy for wind blade infusion?
Sales of in-house epoxy for blade infusion come mainly from Westlake Epoxy, Olin Epoxy and Huntsman. Westlake Epoxy offers EPIKOTE and EPIKURE low-viscosity systems, including a recyclable grade. The Deer Park, Texas site gained ISCC PLUS certification in May 2026, which takes the company's EpoVIVE mass-balance epoxy into Europe and the USA. Olin sells AIRSTONE infusion systems and plans to close the Guarujá, Brazil epoxy plant under a new supply agreement at Stade, Germany. Huntsman supplies ARALDITE infusion formulations for large composite parts.
Which companies sell formulated infusion systems with process support?
Demand for formulated resin systems with on-site know-how is served by Sika, Gurit and Sicomin. Sika's SikaBiresin CR80 data sheet, issued in July 2025, lists three hardeners with pot lives of 60, 190 and 330 minutes. Gurit's Wind Materials net sales reached CHF 40.5 million in the first quarter of 2026, up 17.4% in continued operations at constant exchange rates. Sicomin presented the CMR-free SR 8100 EVO infusion system at JEC World in February 2026, alongside the GreenPoxy bio-based range.
Which companies offer recyclable epoxy for wind blades?
Adoption of recyclable epoxy in wind blades is led by Swancor and Aditya Birla Chemicals. Swancor's recyclable epoxy, made in Taiwan, goes into the 108-meter Siemens Gamesa RecyclableBlades at RWE's Sofia offshore wind farm, announced in August 2025. Leitwind adopted Aditya Birla's Recyclamine technology in April 2026 for the resin and bonding paste of the LS20.X_MK2 blade. Westlake Epoxy also offers a recyclable grade and began a composites recycling collaboration with Alpha Recyclage Composites in June 2025.
Which company supplies curing agents to infusion resin formulators?
Sales of amine curing agents to blade infusion resin formulators come from BASF through the Baxxodur range. BASF sells these hardeners to epoxy formulators serving wind and composites, not finished resin systems to blade makers. In September 2025, BASF moved standard-grade amine production at the Geismar site to 100% renewable electricity credits.
What happened to Hexion's wind blade epoxy business?
Hexion's former epoxy business, including the wind blade systems, now operates as Westlake Epoxy. FMI profiles the portfolio once, under Westlake Epoxy, to avoid counting the same wind epoxy products twice.

Company Selection and Benchmark Notes
Companies are included when cited evidence connects their products or supply roles to this market. Hexion is not scored separately, as its former epoxy business operates as Westlake Epoxy and scoring both would double count the same wind-epoxy portfolio. The FMI benchmark uses documented criteria and scores limited public documentation as Low. Company developments are mapped to demand drivers and product trends through their stated applications.
