• Description: 3-isocyanatepropyltriethoxysilane is an isocyanate functional silane. It is used for the functionalization of numerous compounds with active hydrogen atoms. It hydrolyzes in the presence of moisture to form silanols, which can react with themselves to produce siloxanes. 3-isocyanatepropyltriethoxysilane is mainly applied in these aspects: As crosslinkers for one part moisture curable urethane adhesives, sealants and coatings. As adhesion promoters for one part moisture curable and two part reactive urethane systems. As adhesion promoters for silicone sealants or coatings, to enhance adhesion to organic substrates with active hydrogen atoms. It can provide good wet adhesion to glass, metal and other inorganic substrates, and can provide good thermal, chemical and UV stable performance. It hydrolyzes slower than SiSiB? PC2710, SiSiB? PC2720 is better for applications requring greater open time or enhanced shelf stability.
• Uses: 3-Isocyanatopropyltriethoxysilane is used in preparation of antistatic adhesive and liquid crystal display device.

Photofunctional Eu³⁺/Tb³⁺ hybrid material with inorganic silica covalently linking polymer chain through their double functionalization

10.1016/j.ica.2011.06.036

The study focuses on the synthesis and characterization of photofunctional Eu3+/Tb3+ hybrid materials, which are inorganic silica covalently linked to organic polymer chains through sulfide bridges. The main chemicals used include 2-thiosalicylic acid (TSA), crosslinking reagents 3-chloropropyltrimethoxysilane (CTPMS) and 3-(triethoxysilyl)-propyl isocyanate (TESPIC), tetraethoxysilane (TEOS), europium and terbium nitrates, and organic polymers polyacrylamide (PAM) and polyethylene glycol (PEG). These chemicals serve to create sulfide-bridged molecular linkages and polymeric silane derivatives, which are then assembled into multi-component hybrid materials through co-hydrolysis and co-polycondensation with TEOS. The purpose of these materials is to improve photoluminescence properties by integrating the benefits of both inorganic silica and organic polymers, such as enhanced thermal or optical stabilities, chemical stability, and mechanical strength. The study aims to develop hybrid systems with improved luminescence behavior for potential applications in luminescence and laser fields.
