Quality Control

Our Di-T-Butoxydiacetoxy Silane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure consistency and high purity suitable for industrial and R&D applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
