KH-792 is a silane coupling agent, also known as γ-Aminopropyltriethoxysilane or 3-Aminopropyltriethoxysilane. It is widely used to improve adhesion between organic polymers and inorganic materials, enhancing properties like durability, chemical resistance, and mechanical strength.
Key Uses of KH-792:
-
Adhesives and Sealants: It improves adhesion to inorganic substrates like glass, metals, and ceramics, making it a popular additive in adhesives and sealants.
-
Coatings: In coatings, KH-792 helps enhance the bonding of organic polymers to surfaces, providing better durability and resistance to environmental factors.
-
Composites: In fiberglass and polymer composites, it enhances the adhesion between the matrix and the reinforcing fibers, improving mechanical properties.
-
Plastics: It is used as a surface treatment for fillers like glass fibers, silica, and other reinforcing materials in plastic composites to improve the dispersion and bonding.
-
Rubbers: KH-792 is also used in rubber formulations to improve the adhesion between rubber and various fillers, improving tensile strength and durability.
