Adhesives and Glue
Adhesives and glue are compounds that adhere or bond items together.
They may come from all kinds of natural and synthetic sources.
Most are extremely strong, and are very important
to the construction and auto making industry as well as industrial
applications.
Adhesives and glue are mostly gum and resin. The form a bond that when
applied correctly can laminate just about any material. Some
require as long as 24 hours to dry before the surfaces are held
together.
The applications for adhesives and glue are extensive and include
coatings and composite material such as those using carbon
fibers and fiberglass reinforcement. The chemistry and range of commercially available variations allows cure polymers to be
produced with a very broad range of specialties and properties. In
general, epoxies are known for their excellent strength, chemical and
heat resistance, good to excellent mechanical properties and very good
electrical insulating abilities, but almost any property can be
modified. |
