① Instant bonding
Instant adhesive does not need to be heated and pressurized when used, and has the characteristics of fast curing and high adhesive strength. A 6.45 square centimeter adhesive surface can bear enough tension to lift a car. Such adhesive has played a great role in promoting the continuous production line.


② Bonding of structural members
Structural member bonding refers to the bonding of objects that can bear a long time of load and large stress, such as buildings, vehicles, ships, aircraft, spacecraft and other structural members. Increase speed; At the same time, the surface of the adhesive parts is smooth and smooth, which is conducive to navigation; It also has sealing and anti-corrosion properties.


③ Liquid sealing and plugging
Some adhesives are liquid at normal temperature, which are applied to various joints or parts that need to be sealed to form an elastic adhesive layer, which can replace the ordinary gasket and play a sealing role.


④ Underwater bonding
It can be seen in the construction of dams or bridges, shipbuilding industry and national defense industry. It can connect the prefabricated parts on land with the underwater and underwater parts, thus greatly simplifying the construction process and speeding up the construction progress.


⑤ Hot melt bonding
Hot-melt adhesive is a solid, which can be glued only after being heated and melted into a fluid, and then recovered to a solid after being cooled to form a solid adhesive. The hot-melt adhesive is made of thermoplastic polymer and tackifier.


⑥ Oil surface bonding
The oil surface adhesive does not need to be degreased first, which simplifies the process and has good bonding strength.


⑦ High temperature resistance and ultra-low temperature bonding
General adhesives can withstand temperatures below 100 ℃. Inorganic adhesives can withstand about 600 ℃, among which ceramic adhesive is the best, and can withstand 1300 ℃ high temperature. The ultra-low temperature resistant adhesive can maintain high strength and toughness at - 196 ℃ or even lower temperature - 269 ℃.


⑧ Pressure-sensitive bonding
This product is used for the pasting of commodity labels, the sealing of cartons, the binding of wire harnesses and the protection of the surface of high-gloss metal plates.


⑨ Medical bonding
Medical adhesive has become an indispensable new material in medical treatment. For example, it can play a very good role in the adhesion of the implanted kidney, the connection of blood vessels, the anastomosis of wounds, esophagus or bile ducts, the bonding and repair of dentistry, and the bone connection.

⑩ In addition, there are conductive adhesives for electronic device leads and conductive adhesives with silver powder as the conductor. High transparency optical glass adhesive, photosensitive curing adhesive and electron beam curing adhesive for optical glass bonding.
