Main Function of Coupling Agent
Glass fiber, glass steel: Improve the wet physical and mechanical strength and wet electrical properties of composite materials, and improve the bundleability, protection and processing technology of glass fiber.
Adhesives and Coatings: Improve adhesion and weatherability in wet conditions, improve pigment dispersion, improve wear resistance and cross-linking of resins.
Casting: Increase the strength of the resin sand to achieve height and low gas.
Rubber: Improves the mechanical strength, wear resistance, wet electrical properties and rheology of the product.
Sealant: Improves the adhesion of the wet state, improves the dispersibility of the filler, and the wear resistance of the product.
Textile: Makes textiles soft and plump, improves their water repellency, and adhesion to dyes.
Printing ink: Improves the wettability of adhesion.
Filler surface treatment: Improve the compatibility, wettability and dispersibility of the filler and resin in the resin.
Cross-linked polyethylene: Used to strengthen the strength of cross-linked polyethylene cables and hot water pipes. Durability and longevity.
Main use of coupling agent:
In reinforced plastics, the coupling agent enhances the interfacial adhesion of the resin and the reinforcing material.
At the interface between the resin matrix and the reinforcing material, thecoupling agentpromotes or establishes a strongly bound substance.
Note: The coupling agent can be applied to the reinforcing material or added to the resin, or both.
