Final answer:
Resins are not the weakest cements. They are actually strong and durable materials used in various applications, including dentistry and construction.
Step-by-step explanation:
The statement that the weakest cements are resins because they must be bonded is false. Resins are actually known to be strong and durable materials used in various applications. Unlike other types of cements that must be bonded or mixed with water or other chemicals, resins are usually mixed with a hardener to initiate a chemical reaction that leads to their solidification.
Resin cements are widely used in dentistry for various restorative procedures. For example, composite resin cements are commonly used to bond tooth-colored fillings or dental veneers to natural teeth. These cements provide excellent adhesion, strength, and aesthetics.
Additionally, resins are used in industries such as construction, automotive, and aerospace because of their excellent mechanical properties, including high tensile strength and chemical resistance. Therefore, resins are not the weakest cements; rather, they are considered strong and durable materials.
