Quality Control

Our tert-Butyl Acrylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets exacting industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and at temperatures between 2°C and 8°C to maximize shelf life and inhibit premature polymerization. Keep away from strong oxidizing agents and bases.
