Adhesive Definition and Meaning

Adhaesum is a Latin term that comes from adhaerĕo. We can say that this Latin term can be translated as “capable of sticking” and is the result of the sum of three clearly defined components:
-The prefix “ad-“, which means “towards”.
-The verb “haerere”, which is equivalent to “paste”.
-The suffix “-ivo”, which is used to indicate a passive or active relationship.

It came to our language as an adhesive, an adjective that qualifies what has the ability to fixate on something. For example: “I’m going to tape the cables so they don’t move”, “My mom gave me a notebook with adhesive paper”, “Rummaging through the trunk, the young man found a book patched with adhesive cloth. ”

The concept is also used as a noun to name the material that, when placed between two elements, adheres them to each other, gluing them together: “We use an industrial adhesive to stick the soles of our booties”, “I need an adhesive to fix the poster on the door ”, “ I glued the decorative stones with a transparent adhesive ”.

The adhesives, therefore, achieve that two bodies are united through a superficial contact. The adherence can be due to different causes, from mechanical reasons to magnetic issues.

It is possible to find stickers in different presentations. The liquid adhesives fulfill their function when they dry and establishing binding becomes more resistant. An example of a liquid adhesive is the traditional white glue.

However, within the group of liquid adhesives we find many others such as, for example, those of natural rubber, silicone, acrylic type…

Among the solid adhesives, the most popular are the bars that allow you to glue paper or cardboard, moving them on the surface to be joined. There are also powdered solid adhesives.

Regarding their origin, the adhesives can come from animal sources (such as the glue created from bones or skin) or vegetables (there are adhesives made from corn and potato or potato). They can also develop synthetically (from oil, to name a possibility).

In addition to classifying them by their origin or by their presence, we cannot overlook the fact that such work can be undertaken based on another set of criteria. Thus, for example, one can take into account what its curing is, which would lead us to find four large groups of adhesives:
-Those that are sensitive to pressure.
-Those that are adhesives by evaporation or diffusion.
-The chemically reactive.
-Heat fusion, such as elastomers.

If, on the other hand, we classify them according to the use that they are going to give them, we come across three large groups:
-Adhesives for children’s or domestic use.
-Industrial. Within this category we can find from those that are used for the labeling of bottles to those that are used to make book bindings through those that are used to manufacture furniture of various kinds.
-Professional adhesives, which are the ones used by different workers to carry out the gluing of parts or elements with which they carry out their tasks.
