Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled against stringent specifications for critical parameters such as viscosity, hydroxyl value, acid value, and residual monomer content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory 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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent degradation from atmospheric moisture.
