Quality Control

Our Trimethylsiloxyvinyldimethyl Carbinol is manufactured under a stringent quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications, with purity typically exceeding 98% (by GC). A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability for your production needs.

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, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
