The difference between crosslinking agent and coupling agent - Hubei Co-Formula Material Tech Co.,Ltd.

Cross-linking agent: generally refers to a class of chemicals that participate in the cross-linking reaction of the resin to connect the active functional groups in the resin to form a network structure.

Coupling agent: generally refers to a small molecule chemical containing 3 or more hydrolyzable carbon functional groups, using a small amount can improve the adhesion of the organic-inorganic material interface, the reactivity of the hydrolyzable group and the carbon The functional group can be fixed on the surface of the organic material, that is to say, it can form a bridge between the resin and the interface, increase the adhesion of coatings and adhesives, and use less amount. It can also be used for cross-linking of some materials according to the characteristics of its functional groups, but due to the fast hydrolysis speed, it is generally not used, and the surface drying time after use can be controlled from a few minutes to several hours.
