Quality Control

Our production of this polyester acrylate adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, acid value, color, and degree of functionalization are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance specifications is provided with every shipment to support your quality assurance protocols.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat sources and open flames. For long-term storage, consider blanketing with an inert gas such as nitrogen to prevent oxidation and skin formation.
