Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized for critical parameters such as viscosity, hydroxyl value, acid number, and residual monomer content. Certificates of Analysis (COA) documenting these specifications are available upon request. We adhere to a cGMP-compliant quality management system to guarantee batch-to-batch consistency and supply reliability for our global partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This material is moisture-sensitive; keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and open flame.
