An adhesive that hardens simply by the evaporation of the solvent it is suspended in is known as:
Correct answer: C. Drying adhesive
- A. Reactive adhesive
- B. Pressure-sensitive adhesive
- C. Drying adhesive
- D. Hot-melt adhesive
Explanation
The correct answer is Drying adhesive. These adhesives harden through the evaporation of the solvent in which they are suspended. This is different from other adhesives like reactive adhesives, which harden through a chemical reaction, pressure-sensitive adhesives, which adhere with pressure, and hot-melt adhesives, which solidify upon cooling.

About Industrial Chemistry
Industrial chemistry applies chemical reactions and material properties to the manufacture of adhesives, dyes and polymers. Coverage includes addition and condensation polymerisation, thermoplastics and thermosetting polymers, the structural basis of colour in dyes, and how adhesive composition enables bonding between surfaces.
