Volatility in Epoxy and Isocyanate Feed-Stock Supply Chains

In 2024, volatility hit bisphenol-A and epichlorohydrin feedstocks as China, holding a significant share of global capacity, faced export quotas amid power rationing. This scenario led to price spikes, compelling European formulators to turn to sources in India and the Middle East. Toluene diisocyanate and methylene diphenyl diisocyanate experienced fluctuations. Major players like BASF, Covestro, and Wanhua declared force majeure, resulting in an extension of adhesive lead times. Meanwhile, fixed-price contracts with OEMs hindered Tier 1 suppliers from passing costs downstream, thereby compressing margins and heightening supply-chain risks.

Stringent REACH/CARB VOC Caps Curbing Solvent Systems

In 2025, the REACH update set a cap on VOCs in adhesives, making older solvent products non-compliant unless they were reformulated with higher solids or water carriers. In the same year, CARB slashed the permissible VOC limit for aerospace adhesives, leading to a wave of product withdrawals. Additionally, restrictions on nonylphenol and certain phthalates under SVHC have added to the regulatory challenges. Now, OEMs are proactively including "future-proof" clauses in their tenders, pushing for compliance by 2028. This shift is benefiting vertically integrated formulators who possess the capability to handle both reformulation and certification in-house.

Segment Analysis
