As a key polymer material, epoxy resin is rapidly developing toward green and environmentally friendly, high-performance, and multi-field application directions. This paper systematically analyzes the future development trends of epoxy resin, its technological innovation pathways, and its application prospects in coatings, electronics, new energy, and other fields.
I. Industry Status and Development Background of Epoxy Resins
Epoxy resin, due to its excellent adhesion, chemical resistance, mechanical strength, and electrical insulation properties, has long been widely used in coatings, anti-corrosion, electronic encapsulation, composite materials, and construction fields. As global manufacturing evolves toward high-end and green development, traditional general-purpose epoxy resin is gradually transforming and upgrading to high-performance epoxy resin and environmentally friendly epoxy resin.
Driven by multiple factors including the "dual carbon" goals, tightening environmental regulations, and rising performance demands from end customers, the future development of epoxy resin is no longer limited to capacity expansion, but has entered a new stage centered on technology-driven progress and application innovation.
II. Core Drivers for the Future Development of Epoxy Resins
