Their unique characteristics have led to widespread applications in coatings, inks, adhesives, sealants, and other fields.
Crosslinking Accelerators
Crosslinking refers to the process of forming new chemical bonds between polymer chains through chemical or physical methods. Crosslinking agents are essential for enabling this process by providing reactive groups that allow polymer chains to undergo crosslinking under specific conditions. There are diverse types of crosslinking agents, including radical crosslinkers, ionic crosslinkers, and catalytic crosslinkers. The choice of crosslinking agent depends on the desired crosslinking type, density, and application scenario.
