Quality Control

Our production of this acrylic copolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including solid content, viscosity, pH, and functional group content. Certificates of Analysis (COA) documenting full specification compliance are provided with every shipment. Our quality system supports compliance with relevant industry standards for raw materials used in formulated products.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Avoid freezing and prolonged exposure to temperatures above 40°C. Keep away from strong oxidizing agents. For long-term storage, ensure containers are properly sealed to prevent skin formation or evaporation of volatiles.
