According to a research report published by Spherical Insights and Consulting, The Global Hexamethylene Diisocyanate Market Size was worth around USD 2.16 Billion in 2024 and is Predicted to Grow to around USD 4.79 Billion by 2035 with a Compound Annual Growth Rate (CAGR) of 7.51% from 2025 to 2035. The hexamethylene diisocyanate (HDI) market is growing because the automotive and aerospace industries need high-quality coatings. The market expansion occurs because construction activities increase, technological improvements in polyurethane develop, and VOC regulations mandate the use of sustainable, strong materials.

Market Overview

Hexamethylene diisocyanate (HDI) exists as a colorless to slightly yellow substance that possesses low viscosity and functions as an aliphatic diisocyanate monomer that manufacturers use to create high-performance polyurethanes that maintain their color stability under light exposure. The superior ultraviolet protection, abrasion defense and chemical defense properties of HDI make it a popular choice for high-quality polyurethane coatings and specialized automotive paints and long-lasting elastomers, which the automotive industry uses to obtain more than 60 % of its total market demand. The global market experiences growth because customers from the automotive, aerospace and industrial construction sectors demand premium coatings which provide non-yellowing durability.

The adoption of HDI materials is increasing as companies move towards environmentally friendly coatings that contain low levels of volatile organic compounds. Developing regions such as Asia-Pacific present companies with significant growth possibilities because China's industrial sector keeps growing, and people demand renewable bio-based HDI, and firms develop technologies which minimize application-related volatility and toxicity. India implemented national VOC restrictions for architectural coatings, which will begin enforcement in 2026 after the Ministry of Environment and Urban Affairs completes its draft in May 2025, which requires new projects to use IS 15489 or LEED-compliant materials. Mahacina expanded its Chennai facility into a production plant for low-VOC interior and exterior coatings, which provides green certification assistance to developers.
