Crosslinker
Crosslinkers are reactive chemical agents that form covalent bonds between polymer chains, converting linear or branched macromolecules into a three-dimensional network structure. By introducing intermolecular bridges, crosslinkers dramatically improve mechanical properties, solvent resistance, and thermal stability of coatings, adhesives, and elastomers. They are widely used in waterborne and solventborne systems across automotive, industrial, and packaging coatings.
