Epoxy structural adhesive (epoxy resin structural adhesive) has a wide range of applications, and the wind power generation field is its emerging demand end.

Epoxy structural adhesive, also known as epoxy resin structural adhesive and liquid epoxy resin adhesive, refers to a thermosetting structural adhesive made with epoxy resin as the base material. The appearance of epoxy structural adhesive is usually milky white or light yellow honey-like viscous body with a small smell. It has the advantages of oil resistance, non-corrosion, high strength, aging resistance, fatigue resistance, etc. It is widely used in construction engineering, new energy, aerospace, electronic and electrical , medical equipment, instrumentation and other fields are widely used.

Based on different curing effects and usage methods, epoxy structural adhesives can usually be divided into two-component epoxy structural adhesives and single-component epoxy structural adhesives. Two-component epoxy structural adhesive has the advantages of high bonding strength and good toughness. It can be cured at room temperature and is mainly used for bonding sports equipment, rocket parts and ship structures. The two-component epoxy structural adhesive has corrosion resistance. , temperature resistance and other advantages, can be quickly cured by heating, and is mainly used for bonding electronic product parts.

Epoxy structural adhesive has a wide range of applications, including construction engineering, new energy, aerospace, electronic and electrical, medical equipment, instrumentation, etc. In the field of construction engineering, epoxy structural adhesives can be used for window sealing, wall crack repair, and cement wall panel reinforcement. In the aerospace field, epoxy structural adhesives can meet the lightweight needs of aircraft parts and are mainly used to produce honeycomb sandwich structures. , composite metal structures, etc.; in the field of electronics and electrical, epoxy structural adhesive has the advantages of good electrical insulation and impact resistance, and can be used to repair wires and plugs.
