Quality Control

Our n-Methylaminopropyltris(Trimethylsiloxy)Silane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specifications and consistent performance for industrial applications. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties 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) nature, containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong acids and oxidizing agents.
