Quality Control

Our 1,3-Divinyl-1,1,3,3-Tetramethoxydisiloxane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents.
