Reactive diluents are critical components in the formulations of coatings, adhesives, and composites, designed to reduce viscosity and enhance product performance without compromising durability. They chemically integrate into polymer networks, resulting in improved application efficiency and superior end-use characteristics.
With global regulations tightening around volatile organic compound (VOC) emissions and the push for sustainable manufacturing accelerating, the significance of reactive diluents has increased manifold. Innovations in bio-based and low-VOC diluents support the industry’s sustainability goals while providing improved curing, adhesion, and resistance properties. These factors make reactive diluents essential for industries such as automotive, construction, electronics, and industrial coatings.
According to BIS Research, the reactive diluents market was valued at $1.13 billion in 2024 and is expected to grow robustly, reaching $2.13 billion by 2034, reflecting the sector’s pivotal role in developing greener and high-performance materials.
