Quality Control

Our production of this polymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and solids content to ensure it meets the precise requirements for resin formulation. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and performance reliability for your manufacturing process.

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 product is light-sensitive and easily oxidized; prolonged exposure to air, heat, or light should be avoided to maintain stability and prevent premature polymerization or gelation.
