Quality Control

Our production of this acrylic copolymer ammonium salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including measurement of solids content, pH, viscosity, and mechanical stability, to ensure it meets precise performance specifications. A Certificate of Analysis (COA) detailing these results is provided with each shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Protect from freezing.
