Quality Control

Our 3-Hydroxy-2,2-Bis(Hydroxymethyl)Propyl Acrylate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including assay, purity profiling, and impurity quantification, to ensure it meets precise specifications for high-performance applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance 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/59-77°F). As this product is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame. Isolate from strong oxidizing agents and polymerization initiators.
