Quality Control

Our Rosin, Reaction Products With Acrylic Acid is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets defined specifications for critical parameters such as acid value, softening point, and color. Certificates of Analysis (COA) are available upon request to support your quality assurance protocols.

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 material is easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket) to maintain optimal quality. Keep away from strong oxidizing agents.
