Quality Control

Our production of 1,2-Benzenedicarboxylic Acid Di-2-Propenyl Ester Polymer With Ethyl 2-Propenoate And 2-Methyl-2-Propenoic Acid adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against critical parameters including solid content, viscosity, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these results are available upon request, providing full traceability and compliance data for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For optimal performance, allow the material to equilibrate to room temperature before use if stored in a cold environment.
