I’m not talking about like water or stuff like that, I mean like superglue or a glue stick or duct tape or so on.

I guess technically it would be protons and electrons that attract and stick to one-another
Molecular bonds between the materials.
Some things get a little cozy together, and the edges of their molecules attract a bit. This gets you things that are a little sticky. Gecko feet on windows is an example, as are most weak tapes.
Others react with contact and become part of each other. This leads to very strong bonds, think industrial epoxies and superglue.
I’m pretty sure it’s that it starts liquid so it sorta seeps in to the things it touches. Then it hardens quickly so in a way it’s sorta mixed into the things it’s stuck to.
The stickiness of the adhesive is caused by molecular bonds, and its strength depends on how much stress is needed to pull those bonds apart. Every substance contains molecules that have a positive or negative charge. For two substances to bond, their opposing charges need to be attracted to each other in the exact amount of charge. When the glue dries over a surface, it hardens, causing the molecules to stick together.
