Quality Control

Our Pentaerythritol Trimethylacrylate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, 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 at room temperature (15-25°C/59-77°F). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen). Keep away from strong acids, bases, and sources of heat or ignition.
