Several leading producers have unveiled pilot projects for bio-based diluents, particularly in automotive and electronics applications, where compliance and eco-labelling are valued. This trend is gradually transitioning from niche adoption to mainstream commercial availability as cost competitiveness improves.
Challenges in the epoxy active diluent sector are primarily linked to volatility in raw material prices and logistics constraints. Feedstocks such as epichlorohydrin and bisphenol-A have experienced frequent price fluctuations due to supply disruptions, regulatory scrutiny, and energy market swings. Producers are under pressure as input cost surges compress operating margins, while downstream customers resist proportional price adjustments. Import-dependent regions such as South Asia and parts of Europe face heightened risk from freight cost spikes and port congestion. Smaller manufacturers struggle to maintain profitability when supply contracts are short-term and hedging options are limited. Market fragmentation and intense competition also prevent easy pass-through of costs, leading to thinner margins. Some companies are countering this challenge by forward-integrating into resin production, while others are exploring long-term offtake agreements with feedstock suppliers. Nevertheless, margin pressure remains a defining hurdle, influencing pricing stability and investment decisions across the epoxy active diluent ecosystem.
