6. Bonding on Oily Surfaces
Adhesives for oily surfaces do not require prior degreasing of the surface. This simplifies the process and provides good bonding strength.
7. High - temperature and Ultra - low - temperature Bonding
Ordinary adhesives can withstand temperatures below 100℃. Inorganic adhesives can endure around 600℃, among which ceramic adhesives are the best, capable of withstanding a high temperature of 1300℃. Ultra - low - temperature - resistant adhesives can maintain high strength and toughness at - 196℃, or even at an even lower temperature of - 269℃.
8. Pressure - sensitive Bonding
This type of product is used for pasting commodity labels, sealing cartons, bundling wire harnesses, and protecting the surfaces of highly polished metal plates, etc.
9. Medical Bonding
Medical adhesives have become an indispensable new material in the medical field. For example, they can play a very good role in the adhesion of human kidneys, the joining of blood vessels, the anastomosis of wounds, esophagus or biliary tract, dental bonding and restoration, and bone connection.
10. Conductive Bonding of Electronic Device Leads
In addition, there are conductive adhesives used for the conductive bonding of electronic device leads, with silver powder as the conductor. There are also highly transparent optical glass adhesives for bonding optical glass, photosensitive curing adhesives sensitive to light, and electron - beam curing adhesives.
