Everything liquid contains a solvent. That's basic high school chemistry. Even water is a solvent, and used to be called the "universal solvent" because it dissolves so much different material.
Any, and every paint, glue, or other compounds that contain a carrier that evaporates contain solvents.
Hexanes are a chemical family that uses a specific chemical bond pattern. ALL the chemical compounds using that pattern are "hexanes" but can be widely different in their effects depending on the specific elements and combinations making up the compound.
Hexanes, heptanes, peptanes, octanes, along with many other "-anes" and "-ides" and "-ites" and "-ates" and many other terms are terms identifying chemical compound formulations and construction, and by themselves don't tell you much about what any specific compound is, or does.
