Abstract
Epoxy resin, a globally prevalent organic material, accounts for 81% of total sales in coatings, composite materials, and construction sectors. Its exceptional corrosion resistance makes it the preferred choice for buildings, ships, and automobiles. Epoxy resin is widely used in the automotive industry due to its excellent corrosion resistance, chemical resistance, and high adhesion. Applications include surface painting and repainting of vehicles, as well as manufacturing body components such as engine covers, doors, and bumpers, and interior parts like instrument panels and seat frames. This paper systematically analyzes the performance characteristics and influencing factors of various epoxy resins, while documenting current modification techniques. It details how different modifiers enhance resin properties, summarizes curing types and mechanisms, and provides a comprehensive review of curing structures. Epoxy resin modification is required in applications due to its properties, such as toughness, flammability, chemical resistance, mechanical properties, and electrical conductivity. The materials involved include organic materials, nanomaterials, fibre materials, elastomer toughening, halogens, and thermoplastic polymer composites. The study concludes with research on epoxy resin applications in construction, shipbuilding, and automotive industries. Further research could focus on modifying and curing processes for epoxy resin, particularly in corrosion-resistant and high-temperature applications. The ongoing study of epoxy resin materials remains a promising area for technological advancement.
