Quality Control

Our Resin Acids And Rosin Acids Polymerized, Zinc Salts is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and compliance with industry specifications. Certificates of Analysis (COA) detailing key parameters such as zinc content, softening point, acid value, and color 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, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong oxidizing agents.
