Well, the quick and dirty answer to your question is that they mix a batch of chemicals together in proper formulation, and use solvents to prevent the glue from drying and adhering to everything. When the solvents evaporate (usually upon exposure to air), then the glue becomes super adhesive.
It's very similar to how paint or nail polish is made without instantly hardening and drying. Solvents.
(HINT: To see science in action, paint a fingernail with nail polish, and after only a few seconds run it under cool water. Notice the color doesn't run off? And now notice how the nail is suddenly dry and set? That's because the water just helped to rinse away the solvents! Only the nail polish was left behind to set quickly!)

Water-based glues use water as a solvent instead of chemicals. They work slower than chemical solvent glues; however, they are not flammable. This category comprises such glues as white glue and powdered casein glue, made from milk protein and mixed at home or in the shop.
Two part glues include epoxy and resorcinol, a crystalline phenol that can be synthesized or made from organic resins. One part contains the actual glue; the other part is a catalyst or hardener. Two part glue is very useful for working with metals (automobile dent filler is a two part glue) but must be mixed properly to work well.
Animal hide glues are useful for woodworking and veneer work. Made from the hides as well as the bones and other portions of animals, the glue is sold either ready-made or as a powder or flake that can be mixed with water, heated, and applied hot.
Cyanoacrylate glues, usually referred to as C.A.s, typify the newest and strongest of modern glues, which are made from synthetic polymers. A polymer is a complex molecule made up of smaller, simpler molecules (monomers) that attach to form repeating structural units. Once a polymeric reaction has been catalyzed, it can be difficult to halt: the natural impulse to form polymeric chains is very strong, as are the resulting molecular bonds—and the glues based upon them. In the home and office, small quantities of C.A.s are useful for
