Quality Control

Our Trimethylpentanediol/Adipic Acid/Isononanoic Acid Copolymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications 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 product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product properties.
