Quality Control

Our production of this terpolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer residue, solids content, viscosity, pH, and glass transition temperature (Tg) are rigorously monitored. A Certificate of Analysis (COA) detailing all relevant specifications is 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, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive). Keep away from strong oxidizing agents, acids, and bases. For long-term storage, ensure containers are sealed under an inert atmosphere to prevent skin formation or polymerization.
