Process	Adhesive bonding (gluing)
	Adhesive bonding can be used to join most materials together. The advantages include that different materials can be joined, that no heat need to be applied, that high strength can be achived and that "hidden surfaces" can be joined. Disadvantages are that the joints loose strength at higher temperatures and the severe demands to clean surfaces and narrow tollerances when bonding. Bonding is achieved by pressing clean activated surfaces together after applying a bonding agent (the "glue"). The agent cures using either oxygen (normal paper glue), water (e.g. polyurethane glue) or a chemical reaction in a two component bonding agent (e.g. epoxy). Joints made with adhesive bonding are characterized by good strength (when done corectly), by the facts that no or only little heat is introduced to the parts and that many different materials can be joined.
