• Isocyanatopropylmethyldiethoxysilane

    Isocyanate functional silane, the diethoxy analog of the more common dimethoxy isocyanatopropyl silane. Difunctional grade giving lower crosslink density than the trifunctional isocyanatopropyl silanes, with slower hydrolysis than the methoxy grade for longer working time. Used as a coupling agent and resin modifier in STP (silane-terminated) polymer systems.

  • Isocyanatomethyltrimethoxysilane

    Isocyanate functional silane on a short methylene spacer, trifunctional trimethoxy grade. Used mainly to end-cap MS polymer and silane-modified polyurethane (SPUR) backbones, giving a faster-curing, higher-crosslink alternative to the propyl-spacer isocyanate silanes.

  • Isocyanatomethyltriethoxysilane

    Isocyanate functional silane on a short methylene spacer, triethoxy grade. Slower to hydrolyze than the trimethoxy analog, giving longer working time in MS polymer and silane-modified polyurethane end-capping, and also functions as a crosslinker and tackifier improving the bond between rubber and inorganic substrates.

  • Isocyanatopropyldimethylmethoxysilane

    Isocyanate functional silane. Monofunctional grade — dimethyl plus a single methoxy group on silicon — so it caps a chain end without adding crosslink density, unlike the di- and trifunctional isocyanatopropyl silanes already in the range. Used where isocyanate reactivity is wanted without building network density.

  • Isocyanatomethyldimethoxysilane

    Isocyanate functional silane. The isocyanate group sits on a short methylene bridge to silicon rather than the more common propyl spacer, and the silicon carries a methyl plus two methoxy groups — a difunctional grade used mainly to build and modify MS polymer (silane-terminated polyether) backbones.

  • 3-Isocyanatopropyltriethoxysilane

    Isocyanate functional silane. The isocyanate group reacts with hydroxyl and amine terminated polymers, which makes this the standard reagent for silane-modifying polyurethanes and polyethers into moisture-curable hybrid polymers. Also used directly as an adhesion promoter in PU systems. Releases ethanol on hydrolysis.

  • 3-Isocyanatopropyltrimethoxysilane

    Isocyanate functional silane. The isocyanate group reacts with hydroxyl and amine terminated polymers, which makes this the standard reagent for silane-modifying polyurethanes and polyethers into moisture-curable hybrid polymers. Also used directly as an adhesion promoter in PU systems. Releases methanol on hydrolysis.

  • (3-Isocyanatopropyl)dimethoxymethylsilane

    Isocyanate functional silane. Difunctional grade, which caps the chain end without building a dense network — used to keep modulus low in silane-modified polymers.
