Quality Control

Our Photoinitiator Rc 2184 is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatographic purity analysis and performance testing in standard formulations, to ensure consistent activity and reliable curing performance. Certificates of Analysis (COA) documenting key parameters such as assay, absorbance, and residual solvents are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, containers should be kept sealed until ready for use to maintain optimal efficacy.
