Chemical methods of assembly include the use of
adhesives, adhesive tape or cements.
These methods are readily used for attaching awkwardly
shaped or fragile materials. Adhesives are also frequently
used for leak proof assembly of dissimilar materials. The
strength of chemical bonds is limited by the tensile
strength of the bonding agent or its degree of adhesion to
the substrate. Chemical methods may require longer cycle
times and part fixturing as the adhesive or cement cures.
Solvent cements may be used in select cases, usually with
like materials, to provide a strong leakproof bond.
