Coupling agent is a chemical substance that can improve the bonding force between resin and reinforcing material in reinforced plastics.
The coupling agent is a substance that promotes or establishes a strong bond at the interface between the resin matrix and the reinforcing material.
Note: The coupling agent can be applied to the reinforcing material or added to the resin, or a combination of both.
Application areas and main functions:
Glass fiber and glass fiber reinforced plastic: Improve the wet physical and mechanical strength and wet electrical properties of composite materials, and improve the clustering, protection and processing technology of glass fiber.
Adhesives and Coatings: Improve wet adhesion, weather resistance, improve pigment dispersion, improve abrasion resistance and resin crosslinking.
Casting: Increases the strength of resin sand. In order to achieve high, low gas.
Rubber: Improve the mechanical strength, abrasion resistance, wet electrical properties and rheology of products.
Sealant: Improve the adhesion in wet state, improve the dispersion of fillers, and improve the wear resistance of products.
Textiles: Soften and plump textiles, improve their water repellency and adhesion to dyes.
Printing Inks: Wetting to improve adhesion.
Filler surface treatment: Improve the compatibility, wettability and dispersibility of filler and resin in resin.
Cross-linked polyethylene: used to enhance the strength of cross-linked polyethylene cables and hot water pipes. Durability and service life.
