Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as acid value, hydroxyl value, viscosity, solids content, and color. We adhere to a robust Quality Management System to guarantee batch-to-batch consistency and performance reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its properties, this material should be stored under conditions that minimize oxidation. Keep container tightly sealed when not in use to prevent skinning or moisture absorption.
