Quality Control

Our Dodecylmethyldiethoxysilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all relevant parameters is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and degradation.
