3-Isocyanatopropyltrimethoxysilane, also knonw as A-Link 35, GF 40 or KBK 9007, is a commercial silane with isocyanate functionality. It owns the bi-functionality of a reactive isocyanate group and a hydrolysable alkoxy group. The presence of the trimethoxy group makes 3-Isocyanatopropyltrimethoxysilane to hydrolyze rapidly and bond with inorganic materials tightly. Alkoxy groups of isocyanate silanes can hydrolyze to form a reactive silanol group and offer superior adhesion to a wide range of inorganic substrates.
Our 3-Isocyanatopropyltrimethoxysilane can easily react with active hydrogen in organic polymers. The 3-Isocyanatopropyltrimethoxysilane with high functionality can be used as the equivalent of Wacker GENIOSIL GF 40 or Momentive Silquest A-Link 35.
1. NCO-free polyurethane systems.
2. Moisture curing at room temperature.
3. Can be used as one-component or two-component.
4. It has a wide range of synthesis and formulation design.
5. Improved adhesion to different substrates.
6. Improved UV stability.
7. good storage stability.
8. Excellent chemical resistance.
9. Can be used as a low, medium and high modulus sealant.
1. Adhesive and Sealant Industry
It is used as a coupling agent and adhesion promoter in the formulation of adhesives and sealants. It enhances the bond strength between different substrates, such as metals, glass, ceramics, and plastics.
2. Surface Treatment
(3-Isocyanatopropyl)trimethoxysilane is employed as a surface modifier to improve the adhesion and compatibility of coatings, paints, and surface treatments. It enhances the bonding between the substrate and the applied coating, leading to improved performance and durability.
3. Composite Materials
In the field of composite materials, this silane coupling agent acts as a surface treatment agent. It enhances the adhesion between fibers (such as glass fibers) and polymer matrices (such as epoxy or polyester resins), resulting in stronger and more durable composite structures.
4. Polymer Modification
It is used in polymer synthesis and modification processes to introduce functional groups onto polymer chains. This helps enhance the compatibility between polymers and fillers, improve the mechanical properties, and provide better adhesion to other materials.
5. Coatings and Paints
The addition of (3-Isocyanatopropyl)trimethoxysilane in coatings and paints improves their adhesion, durability, and chemical resistance. It also provides better moisture resistance and reduces the tendency of coatings to crack or peel.
6. Surface Priming
In certain applications, this silane compound is used as a surface primer to enhance the adhesion between the substrate and subsequent layers of coatings or adhesives.
