Binding agents are substances that help hold materials together, enhancing their cohesion and stability. They are commonly used in various industries, including construction, food production, and pharmaceuticals. Examples of binding agents include glue, cement, and starch, each serving specific purposes based on the materials they are combining. In the context of food, binding agents like eggs or flour help maintain the structure of dishes such as meatballs or baked goods. In construction, binding agents like mortar are essential for joining bricks and stones, ensuring the durability of buildings and structures.
