Quality Control

Every batch of Uvithane 783 is manufactured and tested under a strict quality management system to ensure consistent performance and purity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing detailed data for key parameters such as viscosity, color, acid value, and functional group content.

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). Keep away from strong acids and organic solvents. Under these conditions, the product has a recommended shelf life. Once opened, containers should be purged with an inert gas (e.g., nitrogen) before resealing to prevent moisture absorption and premature polymerization.
