In general, adhesives have a wide range of properties depending on the type of adhesive and the applications they are designed for. They can range greatly in flexibility, working time, shelf life, chemical resistance, and much more.  Some adhesives are also given special properties with unique applications in mind. These specialty adhesive properties may include the capacity to withstand extreme heat or cold, the ability to come in contact with food products, or the capability to break down into non-toxic compounds.
