What is 3-Isocyanatepropyltriethoxysilane and How to Use It?

3-Isocyanatepropyltriethoxysilane (CAS No. 24801-88-5) is a versatile silane coupling agent that can be used to improve the adhesion and compatibility of various materials. It has two functional groups: an isocyanate group and an ethoxysilyl group. The isocyanate group can react with compounds that have active hydrogen atoms, such as alcohols, amines, carboxylic acids, and water. The ethoxysilyl group can hydrolyze in the presence of moisture to form silanols, which can further condense to form siloxanes.

3-Isocyanatepropyltriethoxysilane has many applications in different industries, such as:

– As crosslinkers for one-part moisture-curable urethane adhesives, sealants, and coatings. It can enhance the bonding strength and durability of these products to various substrates, such as glass, metal, wood, and plastic.
– As adhesion promoters for one-part moisture-curable and two-part reactive urethane systems. It can improve the wetting and dispersion of fillers and pigments, and increase the resistance to water, heat, and chemicals.
– As adhesion promoters for silicone sealants or coatings, to enhance adhesion to organic substrates with active hydrogen atoms. It can also provide good thermal, chemical, and UV stability.
– As bifunctional reagents for the immobilization of cellulose derivatives onto silica matrix to generate bonded type of chiral stationary phases (CSPs) for chromatography.
– As precursors for the synthesis of luminescent hybrid materials by grafting with organic compounds that have amino or hydroxyl groups .
– As precursors for the synthesis of metal-organic frameworks (MOFs) by reacting with metal salts or complexes.
