Global Epoxy Curing Agents Market - Trends

Rising Demand for Fast and Low-Temperature Curing Agents

End users are increasingly seeking curing agents that shorten project downtime and perform reliably under cold or variable site conditions. In April 2026, Evonik documented ANCAMINE 2505, a modified cycloaliphatic amine providing rapid property development at ambient and low temperatures. It is intended for industrial flooring, coatings, mortars, and containment linings, while offering chemical resistance, limited amine blush, waterspot resistance, and faster return-to-service performance.

Expansion of Latent Curing Agents for One-Component Systems

Latent curing agents are gaining importance because they enable pre-formulated, one-component epoxy products with extended storage stability and controlled heat activation. Evonik’s April 2026 product information for ANCAMINE 2441 highlights its use in one-component heat-cured adhesives, powder coatings, potting compounds, coatings, and hot-melt prepregs. The modified polyamine combines low-temperature activation, formulation shelf stability, improved green strength, and high glass-transition temperature for automated industrial bonding processes.

Greater Use of High-Performance Accelerators in Electronics and Composites

Demand is increasing for curing agents that provide high crosslink density, shorter processing cycles, and temperature resistance in electronics and composite manufacturing. Evonik’s May 2026 technical document for IMICURE EMI-24 identifies a liquid imidazole functioning as both a curing agent and accelerator. Its applications include printed-circuit-board laminates, filament-wound components, castings, adhesives, and coatings, with benefits such as shorter B-stage curing, reduced solvent requirements, long pot life, and higher glass-transition temperatures.

Adoption of Certified Renewable and Mass-Balance Raw Materials

Epoxy suppliers are introducing independently certified renewable-attributed materials without requiring customers to change processing or performance specifications. In May 2026, Westlake Epoxy’s Deer Park, Texas, facility received ISCC PLUS certification, extending its mass-balance offering across Europe and the U.S. The certification supports traceable renewable, bio-circular, and circular feedstocks for epoxy materials used in coatings, construction, wind energy, composites, automotive, and electronics.

Development of Recyclable Thermoset Epoxy Systems

Circularity is moving beyond bio-based feedstocks toward curing agents that allow thermoset composites to be chemically dismantled after use. In its 2026-published ESG report, Aditya Birla Chemicals highlighted Recyclamine, which uses specially engineered curing agents with cleavable crosslinking points. The technology enables recovery and reuse of reinforcing fibres and polymer matrices from epoxy composites, supporting end-of-life recycling in wind energy, automotive, aerospace, and industrial-equipment applications.

Localization of Distribution and Technical Support in Asia

Global manufacturers are strengthening regional distribution networks to provide faster supply, formulation assistance, and application-specific technical support in high-growth Asian markets. In February 2026, Westlake Epoxy expanded its distribution partnership with Brenntag to South and West India. The agreement covers epoxy solutions, including EPIKURE curing-agent products, for coatings, adhesives, and construction, reflecting rising demand for locally supported formulations that address regional processing, performance, infrastructure, and regulatory requirements.

Global Epoxy Curing Agents Market Key Development

In April 2026, Evonik launched Ancamine 2875, a modified polyamine epoxy curing agent developed for flooring and coating applications. The product combines ultrafast curing with extended working time and provides strong adhesion to cold and damp concrete. It is formulated without alkylphenol accelerators, supporting safer and lower-emission epoxy systems. The curing agent also meets ASTM F3010 requirements for moisture-vapor-barrier coatings and can deliver less than 0.1 perm performance at a coating thickness of 12 mils. (Source: Evonik)
In April 2026, Evonik introduced Ancamine 2873, an ultra-low-emission epoxy curing agent designed for protective and marine coatings applied under cold and humid conditions. The product enables reliable film formation and rapid property development at temperatures as low as 5°C. It also provides a long workable pot life, early water resistance, strong substrate adhesion and corrosion protection. The innovation supports the development of ultra-high-solids coatings with reduced volatile organic compound emissions. (Source: Evonik)
In June 2026, researchers reported a highly bio-based liquid latent curing agent called DAMIM for sustainable one-component epoxy formulations. The agent was synthesized through a mild, solvent-free reaction involving imidazole, bio-sourced dimethyl itaconate, and plant-oil-derived dimer acid. Its room-temperature liquid form, curing latency, and intrinsic toughening capability could support safer storage, easier processing, and lower dependence on petroleum-derived curing chemicals in adhesives, coatings, electronics, and composites.
In January 2026, an ACS study reported a thymol-derived aromatic diamine hardener for fully bio-based epoxy thermosets and high-strength adhesives. The innovation addresses the limited availability of renewable aromatic amine curing agents, which are generally required to achieve high thermal and mechanical performance. Commercial development of such hardeners could support bio-based structural adhesives, electronics, transportation components, coatings, and composite materials without completely sacrificing the properties associated with conventional petroleum-based aromatic amines.
