Epoxy sealant is a high-strength, superior electrical performance, and high surface gloss adhesive formed by mixing epoxy resin and curing agent. This sealing adhesive can cure at room temperature and has characteristics such as high transparency, high adhesion, waterproofing, high temperature resistance, and corrosion resistance.
Widely used in electronic and electrical equipment, it has strong structural support and mechanical protection capabilities after curing. Due to its relatively low price, it is widely used in the automotive industry, consumer electronics components, wind power equipment, aerospace and other fields to enhance the mechanical structural stability and performance stability of these components in harsh environments.
