Epoxy resin is a polymer compound composed of epoxy groups and benzene rings, which has good chemical stability and mechanical properties. It can cure at room temperature to form a hard and durable material, widely used in fields such as coatings, adhesives, and electronic packaging. According to different molecular structures and curing conditions, epoxy resins can be divided into thermosetting epoxy resins and thermoplastic epoxy resins. Thermosetting epoxy resin forms a three-dimensional network structure during the curing process, which has high mechanical strength and chemical corrosion resistance. It is commonly used in the manufacture of composite materials, anti-corrosion coatings, etc. Thermoplastic epoxy resin can be repeatedly heated and cooled at a certain temperature, with good fluidity and flatness, and is commonly used in the manufacture of electronic packaging materials, adhesives, etc.
