Applications of LS-ND43 Dichloromethyltriethoxysilane
1. Alpha-functional silane synthesis
Used as a chemical intermediate in substitution and silane modification reactions for producing alpha-functional silanes. Verify residual chloride content and product purity before downstream use.
2. Custom silane intermediate development
Applicable where both dichloromethyl and triethoxysilyl functionality are required in a single intermediate structure.
3. Modified siloxane and resin intermediates
Used in synthesis routes for modified siloxane or resin intermediates. Verify compatibility, side reactions, and material properties in the target system.
4. Surface treatment precursor
Used as a precursor in the preparation of surface treatment agents. Direct substrate application requires careful testing due to chlorinated functionality and moisture sensitivity.
5. Moisture-curable silane R&D
Used in R&D evaluation of moisture-curable silane systems. Verify cure behavior, by-product formation, and storage stability before scale-up.
Packaging of LS-ND43 Dichloromethyltriethoxysilane
In 20kg pail, 200kg drum and 950kg IBC
Safety and Storage of LS-ND43 Dichloromethyltriethoxysilane
Keep in a cool, strictly dry, and well-ventilated environment, aggressively avoiding direct sunlight, heat, sparks, and open flames. The product is highly sensitive to ambient moisture and may release trace amounts of hydrogen chloride (HCl) upon severe hydrolysis. The shelf life is a minimum of 24 months from the date of manufacture when stored at or below 25°C in tightly sealed, original unopened containers.
