Cross-linking agent, in the context of materials science and chemistry, refers to a substance that facilitates the formation of covalent bonds between polymer chains or other molecules.
Cross-linking agents are used to modify and enhance the properties of materials. By forming bonds between molecules or polymer chains, they can improve mechanical strength, thermal stability, chemical resistance, and other performance characteristics.
Silanes: Silane-based cross-linkers like alkoxysilanes or mercaptosilanes are commonly used in polymers, coatings, and adhesives.
Cross-linking agents are employed in various industries and products, including:
Plastics and Rubbers: To improve strength, elasticity and thermal resistance.
Coatings and Adhesives: Enhancing durability, chemical resistance, and adhesion.
Composites: Strengthening fibers and matrices in fiberglass, carbon fiber, and other composite materials.
