Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed against strict in-house specifications to guarantee consistency and performance. Certificates of Analysis (COA) are available upon request, detailing key parameters such as hydroxyl value, viscosity, and moisture content. Our quality management system supports traceability and meets the demands of global supply chains.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
