The global impregnating resins market size reached USD 2.1 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 3.4 Billion by 2033, exhibiting a growth rate (CAGR) of 5.31% during 2025-2033. The growing renewable energy sector, rising demand for electrical insulation, ongoing advancements materials, and automotive industry expansion are primarily driving the market's growth.
Impregnating resins, also known as secondary insulation materials, refer to organic liquid resins diluted with reactive thinners. They contain formaldehyde and are composed of dimers and trimers of the main molecule. They are thick and viscous that are used in the forest products industry for wood modification. Impregnating resins are also used in electric motors, filament winding, generators, home appliances, electrical components, and transformers. They exhibit electrical insulation, protection from climate changes, and mechanical stability. They provide resin protection and enhance heat transfer among iron cores, slot insulations, and wires wending.
The significant growth in the automotive industry across the globe is creating a positive outlook for the market. Impregnating resins are widely used to impregnate starters, electric motors, and alternators in conventional vehicles and electric vehicles (EVs). In line with this, the implementation of various government initiatives to accelerate decarbonization and reduce greenhouse gas (GHG) emissions are favoring the market growth. Additionally, the widespread product adoption for producing transformers, generators, and motors, and impregnating varnishes and wire enamels is acting as another growth-inducing factor. Apart from this, the introduction of water-based impregnation resins that are designed to be more environmentally friendly than conventional products is providing an impetus to the market growth. Moreover, the increasing demand for electrical and electronic components is facilitating the market growth. Resin impregnation of windings and copper wires prevents vibration, provides better insulation, increases heat exchange during regular operation, is resistant to stresses and temperature loads, and reduces the risk of short circuits in the windings, which, in turn, is augmenting the market growth. Other factors, including the widespread utilization of solvent-less impregnating resins, extensive research and development (R&D) activities, and the launch of advanced impregnating resins that makes the motor more protective and provides high mechanical stability, are anticipated to drive the market growth.
