Epoxy adhesive is a type of adhesive that is made from a combination of epoxy resin and a hardener. When the two components are mixed together, they react chemically to form a cross-linked network, which provides a strong and durable bond. Epoxy adhesive is known for its high performance, durability, and chemical resistance, and is able to provide excellent adhesion to a variety of substrates, including metals, plastics, and concrete. It is also able to provide a high degree of mechanical and chemical resistance, making it suitable for use in harsh environmental conditions. Epoxy adhesive is commonly used in a variety of applications, such as automotive and aerospace industries, construction, and electronics. In construction, epoxy adhesives are commonly used to bond steel, to reinforce plates or carbon laminates and to strengthen beams and columns.
