Polyurethane varnishes are being widely chosen due to their excellent flexibility, abrasion resistance, and chemical stability, which are essential for insulating electrical steel laminations under high thermal and mechanical stress. Their ability to provide strong adhesion and superior dielectric properties ensures reliable performance in demanding applications such as high-voltage transformers and industrial motors.
Polyurethane-based varnishes also exhibit resistance to moisture and environmental factors, making them suitable for varied operating conditions. Advances in formulation have enabled the development of low-VOC and eco-friendly polyurethane products, aligning with global sustainability goals and regulatory compliance requirements.
The versatility of polyurethane, combined with its proven performance advantages, has reinforced its widespread use across electrical equipment manufacturing As industries increasingly demand long-lasting and efficient insulation materials, polyurethane varnishes are expected to sustain their leadership in the market.
The transformer application segment is projected to hold 34.8% of the market revenue in 2025, positioning it as the largest application area. Growth in this segment is being driven by the rising global demand for reliable power transmission and distribution infrastructure. Core plate varnishes are critical in transformer manufacturing, where they prevent inter-laminar short circuits, minimize eddy current losses, and extend operational lifespans.
The increasing deployment of transformers in renewable energy grids, urban power networks, and industrial facilities is reinforcing varnish demand. Furthermore, the ongoing replacement of aging power infrastructure in developed economies and rapid electrification in emerging markets are creating new growth opportunities. Transformer manufacturers are prioritizing varnishes that provide superior thermal endurance and mechanical stability to ensure uninterrupted operation in diverse environments.
Regulatory emphasis on energy efficiency standards is also propelling the adoption of advanced varnishes that reduce energy losses As power consumption continues to rise worldwide, transformers will remain a primary end-use driver, sustaining the segment’s leading role in the Core Plate Varnishes market.
Over the decade, consumption of energy has significantly increased over the globe, owing to various factors such as, increasing rate of habitation in urban and rural sector, commercial workspace, growing industrial establishments, per capita consumption, and many more. Most of the energy is lost during transmission from the generation site to distribution centres. In order to recover this energy and minimization of losses, insulation plays an important role in optimizing the power transmission process.
Core plate varnishes is one of the insulation components to the electrical devices and machines. Manufacturers have developed water borne and heat absorbing varnishes to insulate the electrical steel. Properties present in the core plate varnishes reduce the eddy current losses of the electrical components which enhance the efficiency and life of the components.
These core plate varnishes used to insulate the electrical components such as, motor, generators, transformers, and other electromagnetic poles. The application of core plate varnish in saving the energy is a special technology in which coated laminations of the electrical core are not held together by mechanical or welding connection.
Core plate varnishes applies in two steps, in the first step the electrical components coated with varnishes and keep it for drying in an oven in the second step the insulated components undergoes high temperature and pressure test.
