Quality Control

Our resin production adheres to strict batch-to-batch consistency protocols, with quality parameters including acid value, viscosity, solids content, and color closely monitored. While typically produced to industrial grade specifications, manufacturing can be aligned with relevant industry standards based on customer requirements. Certificates of Analysis (COA) detailing key physicochemical properties are provided with every shipment to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Due to its nature, the resin should be kept under an inert atmosphere or with a minimal headspace to prevent skin formation and oxidation. Keep away from strong oxidizing agents.
