Quality Control

Our production of this specialized resin adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) detailing these specifications are available for every shipment to ensure the material meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skinning or oxidation.
