Quality Control

Our production of this urethane acrylate adheres to strict quality management protocols. Every batch is characterized using advanced analytical techniques to ensure consistency in functionality, viscosity, and reactive group content. A comprehensive Certificate of Analysis (COA) detailing assay, residual monomer levels, and key physical properties is provided with each shipment to guarantee it meets your formulation specifications.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
