Most solvents and glues are adhesive. A few mollusks produce a glue with chemical action, and they are being studied.

Chemical bonds, however, only form for very few substrate/adhesive combinations, e.g. between silicone and glass, polyurethane and glass, and epoxy resin and aluminum. For some of these bonded joints it has been demonstrated that chemical bonds account for up to 50% of all the interactions.
