What is Adhesive Forces?
Adhesive forces are attractive forces between molecules of different substances. They are responsible for the adhesion of a liquid to a solid surface and for phenomena such as capillary action (when adhesion > cohesion), wetting of surfaces, and the meniscus shape in a glass tube. Adhesive forces involve intermolecular forces including van der Waals forces, hydrogen bonds, and electrostatic interactions.

No direct hazard from the concept itself. Adhesive products (glues, solvents) may be flammable, irritating, or toxic; always consult SDS for specific adhesive products.
The formula or notation for Adhesive Forces is: W_adhesion = γ_A + γ_B − γ_AB
