Adhesives are substances used to bond materials together, providing structural and functional integrity across a wide range of applications. This category includes various types of adhesives such as epoxies, silicones, cyanoacrylates, and polyurethanes, each tailored for specific bonding needs. Adhesives are crucial in industries such as manufacturing, construction, and automotive for creating strong, durable joints and repairs. They are selected based on properties like curing time, temperature resistance, and material compatibility, ensuring optimal performance in diverse environments and under different stresses.
