Quality Control

Our production of Rosin, Fumarated, Polymer With Glycerol And Pentaerythritol adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as acid value, softening point, color, and viscosity. Certificates of Analysis (COA) documenting these results 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, 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). Keep away from heat sources and open flame.
