At that time, stamp adhesives consisted of naturally occurring raw materials such as molasses, potato starch and occasionally fish glue, but these performed poorly. So, the stamps either stuck together or fell off prematurely and emitted an unpleasant odour. In addition, the stamps had to be moistened before fixing, which was often done by licking.

The glue squeezed out of the heated nozzle is initially hot enough to burn and even blister skin. The glue is sticky when hot, and solidifies in a few seconds to one minute. Hot-melt adhesives can also be applied by dipping or spraying, and are popular with hobbyists and crafters both for affixing and as an inexpensive alternative to resin casting.
Impact glue, contact glue, contact cement, or neoprene glue is a type of solvent-based adhesive which may be used to bond materials such as plastics, laminates, and metal or wood veneers. [1] The term "contact glue" come from the practice of applying adhesive to both surfaces to be bonded; the surfaces are joined once the solvent in the ...
An electrically conductive adhesive is a glue that is primarily used for electronics. The electric conductivity is caused by a component that makes ca. 80% of the total mass of an electrically conductive adhesive. This conductive component is suspended in a sticky component that holds the electrically conductive adhesive together.
A small transformer potted in epoxy. The surface visible on the right is formed by the potting compound that has been poured into the plastic box. In electronics, potting is the process of filling a complete electronic assembly with a solid or gelatinous compound.

In materials science, a polymer blend, or polymer mixture, is a member of a class of materials analogous to metal alloys, in which at least two polymers are blended together to create a new material with different physical properties. [1]
