Quality Control

Our (3-Acryloxypropyl)Tris(Trimethylsiloxy)-Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identification by FT-IR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to relevant industry standards and can support compliance documentation for global supply chains.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent polymerization. Keep away from heat, sparks, and open flame.
