Quality Control

Our production of this acrylic terpolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer content, molecular weight distribution, viscosity, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat sources and open flame. For long-term storage under warm conditions, monitoring for viscosity stability is recommended.
