Quality Control

Our acrylic copolymer is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as solid content, viscosity, pH, and glass transition temperature (Tg). Our production adheres to relevant ISO 9001 standards, and the product is compliant with global regulatory frameworks including REACH. Specifications can be tailored to meet specific customer requirements.

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). Avoid freezing and prolonged exposure to heat sources above 40°C (104°F). Keep away from strong oxidizing agents. Under recommended storage conditions, the product has a typical shelf life of 12 months from the date of manufacture.
