Quality Control

Our production of this specialty polyester resin adheres to strict quality management systems, ensuring batch-to-batch consistency for your formulation needs. Key parameters such as acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with each shipment to guarantee compliance with your technical requirements.

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). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For bulk storage, ensure containers are kept sealed to prevent moisture absorption and contamination.
