The process that converts an adhesive from the applied state to its final solid state is ___.

• A. Curing
• B. Setting
• C. Drying
• D. Hardening

Answer: (A)

Curing is the chemical change that transforms an adhesive from its applied, pliable state into its final solid state, developing full strength and dimensional stability. This typically involves reactions such as polymerization or cross-linking, sometimes driven by heat, moisture, or a catalyst, and it may continue after the adhesive appears set. Setting is merely the initial stiffening and tack of the bond, not the complete development of properties. Drying refers to solvent evaporation without the chemical changes that give the adhesive its full strength. Hardening describes becoming hard, but curing specifically denotes the actual chemical process that yields the final performance. In joining work, ensuring curing completes is what guarantees the joint will perform as designed.
