In reinforced plastics, a chemical substance that improves the interfacial bonding between the resin and the reinforced material. 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 both.
Application areas, main functions:
Glass fiber, glass steel: improve the wet physical and mechanical strength of composite materials, wet electrical properties, and improve the cluster of glass fiber, protection and processing technology.
Adhesives and coatings: improve wet adhesion, weather resistance, improve pigment dispersion, improve wear resistance and resin crosslinking.
Casting: improve the strength of resin sand. To achieve high, low gas.
Rubber: improve the mechanical strength, wear resistance, wet electrical properties and rheology.
Sealant: improve the adhesion of the wet state, improve the dispersion of the filler, the wear resistance of the product.
Textiles: Make textiles soft and plump, improve their water resistance, and adhesion to dyes.
Printing ink: improve the adhesion of wettability.
Filler surface treatment: in the resin to improve the compatibility of filler and resin, wetting, dispersion.
Cross-linked polyethylene: used for cross-linked polyethylene cables and hot water pipes to enhance strength. Durability and service life.
