Product Insights

The aliphatic segment dominated the market and accounted for a revenue share of 42.0% in 2025. This growth is attributed to the superior performance characteristics of aliphatic reactive diluents, including excellent UV resistance, high chemical resistance, weatherability, and durability, making them ideal for applications such as coatings, adhesives, flooring, and composites. In addition, their excellent compatibility with a wide range of epoxy resin systems and ability to reduce viscosity without compromising performance provide manufacturers with greater flexibility in formulation development. Furthermore, the growing demand for high-performance, low-VOC epoxy systems across the construction, automotive, and industrial sectors continues to support segment growth. For instance, in 2025, Evonik offers aliphatic epoxy reactive diluents, including EPODIL 746 and EPODIL 747, to enhance epoxy resin formulations with lower viscosity, improved flexibility, low volatility, and better processing performance for coatings, adhesives, flooring, and composite applications, reflecting the increasing demand for high-performance aliphatic reactive diluents.

The aromatic segment held a significant share in the market. These are a specific type of reactive diluent characterized by their aromatic structure, which plays a significant role in enhancing the properties of composites. These diluents are mainly chosen for their ability to lower the viscosity of resin systems without sacrificing the composite's thermal or mechanical integrity. Due to their aromatic nature, they can provide better compatibility with specific resin formulations, improving the final product's processing characteristics and mechanical properties. Moreover, their reactivity ensures a seamless integration into the polymer matrix, maintaining the strength and durability of the composite.

Application Insights

The paints & coatings segment dominated the market, accounting for a revenue share of 39.0% in 2025. Reactive diluents are widely used in paint and coating formulations to reduce viscosity, improve flow characteristics, facilitate crosslinking, and enhance adhesion, chemical resistance, durability, and weatherability without increasing volatile organic compound (VOC) emissions. The growing demand for high-performance protective coatings across the construction, automotive, marine, industrial, and infrastructure sectors continues to drive product consumption. In addition, the increasing adoption of low-VOC, high-solids coating systems to comply with stringent environmental regulations is further boosting demand for reactive diluents in modern paint and coating formulations.

The composites segment holds a significant share of the market. Growing demand for lightweight, high-strength materials across end-use sectors such as wind energy, aerospace, automotive, and construction is increasing the use of reactive diluents in composite applications. Reactive diluents are essential for reducing resin viscosity, facilitating better fiber wetting, and improving the processing of composite systems without affecting their mechanical and thermal performance. Furthermore, the growing importance of sustainable composite technologies and recycling of materials is supporting manufacturers to come up with novel resin technologies for future generations. For instance, in February 2025, Arkema presented its innovative composite technology at JEC World 2025, including Elium resin-based recyclable composite solutions, such as an eco-design wind turbine blade, in partnership with key industry players.
