Structural adhesives refer to adhesives with high strength (compressive strength > 65MPa, steel-steel positive tensile bonding strength > 30MPa, shear strength > 18MPa). They can bear large loads, are resistant to aging, fatigue and corrosion, maintain stable performance within the expected service life, and are suitable for bonding structural parts that bear strong forces. Generally, construction projects have very high requirements for the strength, durability and corrosion resistance of adhesives. Moreover, as we all know, the construction conditions of most buildings are very harsh. Therefore, there is a greater need for adhesives that can meet the requirements of construction environment, construction technology, etc., and are also of good quality and low price.
