Which term describes the process of cutting into a surface with the use of an acid product?

• A. Etching
• B. Etchant
• C. Desiccate
• D. Micromechanical

Answer: (A)

Etching is the process of cutting into or dissolving a surface with an acid to create microscopic roughness. When the acid is applied, minerals on the surface are partially dissolved, forming tiny pores that increase surface area. This roughened surface helps adhesives or coatings bond more effectively by providing better mechanical interlocking. The acid product used to do the etching is called an etchant, but that term names the chemical, not the process itself. Desiccate means to dry out, which isn’t about altering the surface texture, and micromechanical refers to physical, not chemical, roughening.
