Siwin is a leading manufacturer and supplier of organosilanes for over 15 years.

Siwin isocyanate silanes contain isocyanate groups (-N=C=O) and silane groups (Si-H). This unique structure endows them with both the reactivity of isocyanates and the stability of silanes. The isocyanate groups can react with a variety of functional groups, such as hydroxyl and amino groups, to form stable chemical bonds; while the silane groups provide good water resistance and weather resistance.

Siwin owns a whole series isocyanate silane products include γandα(alpha）isocyanate silanes.

Siwin isocyanate silanes can be used as endcapper agent for STP or SPUR polymers (MS polymer): silane terminated polyurethane and silane terminated polyether.

Siwin-AL31: 3-isocyanatopropyltrimethoxysilane, CAS No. 15396-00-6

Siwin-Al32: 3-isocyanatopropyltriethoxysilane, CAS No. 24801-88-5

Siwin exclusively isocyanate silane:

Siwin-AL1221: α-isocyanatomethyl-dimethoxy-methylsilane, CAS No.: 406679-89-8

Other applications are:

Paint Industry: Isocyanate silanes can serve as cross-linking agents in coatings, enhancing the hardness, wear resistance, and chemical corrosion resistance of the coating. By reacting with other components in the coating, they form a dense network structure, thereby improving the performance of the coating.

Adhesive Field: In adhesives, isocyanate silanes can act as coupling agents, increasing the bonding strength and durability of the adhesive. They can react with active groups on the surface of the bonded material, forming chemical bonds, thereby improving the bonding effect.

Plastic Industry: During the plastic manufacturing process, isocyanate silanes can be used as plasticizers, improving the flexibility and impact resistance of plastics. By binding with the plastic molecular chains, they increase the intermolecular slippage, thereby improving the processing and performance of plastics.

Electronic Materials: Isocyanate silanes are also widely used in electronic materials, mainly for improving the adhesion and durability of the materials.

Medical Field: Due to their good biocompatibility and stability, isocyanate silanes also have applications in the medical field.
