Source: Admet Adhesives come from either natural or synthetic
sources. Some modern adhesives are extremely strong and are
becoming increasingly important in electronic, construction and
aerospace applications. The primary function of adhesives is to
join parts together. Adhesives accomplish this by transmitting
stress from one member (substrate) to another in a manner that
distributes the stress more uniformly than can be achieved with
mechanical fasteners. Adhesive bonding often provides joints
that are mechanically equivalent to or stronger than those
joined by fasteners. For example, an assembly held together by
rivets is limited by the strength of the material under the head
of the rivets. The contact area between the substrates of an
adhesive bond is usually much larger than the rivet underhead
area. The result is an
