Quality Control

Our production of this acrylic copolymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. While specific grades may vary, quality is assured through parameters such as solids content, acid value, viscosity, and pH. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product properties.
