Electronic structural adhesives refer to adhesives with high strength (compressive strength>65MPa, steel-steel positive tensile bond strength>30MPa, shear strength>18MPa) and strong bearing capacity. In use, it can resist corrosion, aging and fatigue, greatly prolong the service life, protect the bonding object from damage, and have high use value. General electronic manufacturing has high requirements on the strength, durability and corrosion resistance of adhesives. In addition, the construction conditions of most electronic products are very harsh. Therefore, electronic structural adhesives have become an indispensable material that can meet the requirements of the construction environment and construction process. Second choice.

Electronic structural adhesive properties:

Electronic structural adhesive is an adhesive invented for bonding structural parts in electronic materials. As a kind of adhesive, its main function is also bonding. Compared with other ordinary glues, it is easy to use, has stronger bearing capacity, is resistant to aging, corrosion, has stable performance, and has high strength. From its composition point of view, Structural adhesive is a kind of glue made of a special resin. It has very good toughness and can bond different materials. Its market demand is very large, especially in the electronic and electrical industry. Due to its neutral curing characteristics, structural adhesives are mainly used for reinforcement, bonding and repairing between parts in engineering structures.

The characteristics of electronic structural adhesives determine that it needs to be used at high frequencies in many connections and fixings. The selection of electronic structural adhesives is particularly important. The important properties of high-quality electronic structural adhesives are mainly reflected in the following aspects:

1. Safety: When we choose electronic structural adhesives, it is best to choose products with national quality and safety certification. 2. Adhesion: When choosing electronic structural adhesive, the first thing to look at is its adhesiveness. As an adhesive, to achieve its function, good adhesiveness is essential. 3. Compatibility: Compatibility means that the electronic structural adhesive will not produce adverse physical and chemical reactions when it contacts with other materials. Compatibility qualification is the basis for ensuring that electronic structural adhesives maintain their own stable performance. 4. Stability: The electronic structural adhesive is directly related to the tensile bonding properties after high and low temperature, water immersion and ultraviolet light. A high-quality electronic structural adhesive with good stability, even after being immersed in water every day, it can still maintain good adhesion.
