Quality Control

Our urethane acrylate oligomers are manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including viscosity, acrylate equivalent weight, color, and residual monomer content to ensure consistent performance and reliability in your formulations. Certificates of Analysis (COA) detailing lot-specific results are available upon request.

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). Keep away from heat, sparks, and open flame. Incompatible with strong acids and organic solvents. For long-term storage under an inert atmosphere (nitrogen), please contact our technical team for specific recommendations.
