Quality Control

Our production of Sunflower/Isophthalic/Phthalic Anhyd./Trimethylolpropane adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting full specification compliance are available upon request, supporting your quality assurance and regulatory 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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
