Applications of LS-94322 1,1,3,3-Tetramethyl-1-[2'-(Trimethoxysilyl)Ethyl]-Disiloxane
1. Silicone polyether synthesis
Used in hydrosilylation reactions with allyl- or vinyl-functional polyethers to prepare silicone polyether intermediates or surfactant structures. Verify reaction conversion, catalyst compatibility, and residual Si–H by synthesis testing.
2. Silane-functional polymer synthesis
Used as reactive intermediate for introducing trimethoxysilyl functionality into vinyl- or allyl-functional polymer systems. Verify reaction conditions and final polymer properties in the target process.
3. Moisture-curable intermediates
Used in the preparation of moisture-curable silane-functional materials requiring both hydrosilylation reactivity and alkoxysilane functionality. Verify cure behavior and storage stability before scale-up.
4. Surface modifier synthesis
Used as intermediate for preparing organosilane surface modifiers for glass, mineral, silica, or metal oxide surfaces. Verify hydrophobicity, adhesion, and durability in the final formulation.
5. Silicone resin and siloxane modification
Used for modifying silicone resins, siloxane intermediates, or hybrid systems. Verify compatibility, viscosity, cure behavior, and final material properties by application testing.
Packing of LS-94322 1,1,3,3-Tetramethyl-1-[2'-(Trimethoxysilyl)Ethyl]-Disiloxane
In 25kg pail and 200kg drum.
Safety and Storage of LS-94322 1,1,3,3-Tetramethyl-1-[2'-(Trimethoxysilyl)Ethyl]-Disiloxane
Store in a cool, dry, well-ventilated environment. Keep away from direct sunlight, heat, and open flames.
The Si–H bond reacts with strong acids, alkalis, heavy metals, and moisture to generate flammable hydrogen gas (H₂); isolate from these materials during storage and handling.
Shelf life: 12 months minimum from manufacture date when stored at ≤25°C in original tightly sealed unopened containers.
