Quality Control

Our 2,2-Bis(Hydroxymethyl)-1,3-Propanediol, Homopolymer, Isononanoate Pentanoate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as acid value, hydroxyl value, viscosity, and color are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong bases and organic solvents. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature is 15-25°C.
