Ningbo Inno Pharmchem Co., Ltd, a leading manufacturer and supplier of specialty chemicals, is proud to introduce (3-Isocyanatopropyl)trimethoxysilane, a highly versatile and effective silane coupling agent. Also known as 3-isocyanatopropyl(trimethoxy)silane or γ-isocyanatopropyltrimethoxysilane, this product is used in various industrial applications, including coatings, adhesives, and composites.

(3-Isocyanatopropyl)trimethoxysilane is a silane coupling agent that provides excellent adhesion, bonding, and compatibility between inorganic and organic materials. This product contains a reactive isocyanate group that can react with hydroxyl groups present in many substrates, such as glass, metals, ceramics, and plastics. The methoxy groups on the silicon atom can undergo hydrolysis and condensation reactions to form a stable and durable siloxane bond with the substrate surface.

One of the main benefits of (3-Isocyanatopropyl)trimethoxysilane is its ability to enhance the mechanical, thermal, and chemical properties of coatings, adhesives, and composites. By acting as a molecular bridge between the substrate and the polymer matrix, this silane coupling agent can improve the wetting, spreading, and flow of the coating or adhesive, resulting in a smoother and more uniform surface. It can also reduce the brittleness, cracking, and delamination of composites by reinforcing the interface and preventing moisture ingress.

To demonstrate the effectiveness of (3-Isocyanatopropyl)trimethoxysilane, let's look at some examples of its applications:

Coatings:

WACKER GENIOSIL GF 40 is a water-based coating system that uses (3-Isocyanatopropyl)trimethoxysilane as a key ingredient. This coating is suitable for various substrates, such as concrete, wood, metal, and plastics, and provides excellent adhesion, durability, and weatherability. The silane coupling agent in this coating enhances the bond strength between the substrate and the polymer binder, reducing the risk of blistering, cracking, and peeling. WACKER GENIOSIL GF 40 also has low VOC emissions, making it a more environmentally friendly option.

Adhesives:

Momentive Silquest Y-5187 is a one-part moisture-curing adhesive that uses (3-Isocyanatopropyl)trimethoxysilane as a reactive diluent. This adhesive is suitable for bonding various substrates, such as metals, plastics, and ceramics, and provides high strength, toughness, and flexibility. The silane coupling agent in this adhesive improves the wetting and penetration of the adhesive into the substrate, resulting in a stronger and more durable bond. Momentive Silquest Y-5187 also has good resistance to water, chemicals, and UV radiation.

Composites:

Momentive Silquest A-Link35 is a silane coupling agent that is used in fiber-reinforced composites, such as glass fiber, carbon fiber, and aramid fiber. This coupling agent can improve the interfacial adhesion between the fibers and the polymer matrix, resulting in a stronger and stiffer composite. The isocyanate group in this coupling agent reacts with the hydroxyl groups on the fiber surface, creating a covalent bond that resists shear and tensile stresses. Momentive Silquest A-Link35 also has good thermal stability and compatibility with various resins, such as epoxy, polyester, and vinyl ester.

(3-Isocyanatopropyl)trimethoxysilane is also known by other names, such as Silane coupling agent SI-335, 3-isocyanatopropyltrimethoxysilicon, 3-(Trimethoxysilyl)propyl isocyanate, and 3-(triethoxysilyl)propylisocyanate. Regardless of the name, this silane coupling agent is a valuable tool for improving the performance and durability of various industrial products.
