Quality Control

Our production of this specialty polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including monomer residue, molecular weight distribution, viscosity, acid value, and glass transition temperature (Tg) to ensure consistent performance in your formulations. Certificates of Analysis (COA) detailing these specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for the specific grade (typically between 15-25°C). Keep away from heat sources and open flames. To prevent premature polymerization or viscosity increase, storage under an inert atmosphere (e.g., nitrogen) may be recommended for certain grades.
