The wetting of an adherent surface by an adhesive is related to________________?
Correct answer: A. Surface energy of the adherent
- A. Surface energy of the adherent
- B. Surface texture of the adherent
- C. Surface tension of the adherent
- D. Nature of the adherent that is crystalline or amorphous
Explanation
Wetting depends strongly on the surface energy of the adherend: high surface energy promotes spreading of the adhesive and better contact. Surface texture can influence retention, but it is not the primary definition of wetting.
