CFS-838 3-Glycidoxypropyltrimethoxysilane (GPTMS/KH560)

CAS No.: 2530-83-8

CFS-838 3-Glycidoxypropyltrimethoxysilane (GPTMS/KH560) is a versatile epoxy silane coupling agent containing both hydrolyzable methoxy groups and an epoxy functional group. It promotes the interfacial bonding between organic polymers and inorganic materials.

CFS-838 effectively improves the adhesion and compatibility between resins and inorganic materials such as glass, metals, and mineral fillers, while enhancing the mechanical properties, water resistance, and durability of composite materials.

Key Functions

CFS-838 3-Glycidoxypropyltrimethoxysilane (GPTMS/KH560) can be used as:

· Silane coupling agent

· Adhesion promoter

· Surface modifier

· Resin modifier

It improves the bonding between organic resins and inorganic materials and is particularly suitable for epoxy, polyurethane, acrylic, and silicone resin systems.

CFS-838 also improves the dispersion and bonding of inorganic fillers in resin systems, thereby enhancing the overall performance of composite materials.

Applications

CFS-838 3-Glycidoxypropyltrimethoxysilane (GPTMS/KH560) is widely used in:

· Epoxy resins

· Polyurethanes

· Acrylic resins

· Silicone resins

· Adhesives and sealants

· Coatings

· Glass fibers and composites

· Surface treatment of mineral fillers and pigments

· Plastic modification

In adhesives, coatings, and sealants, CFS-838 improves adhesion, water resistance, and durability between resins and inorganic substrates.

In glass fiber, mineral filler, and composite applications, it improves the bonding between fillers or fibers and polymer matrices, enhancing the mechanical strength and long-term stability of composite materials.
