Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is controlled against established specifications for critical parameters such as thiol content, epoxide equivalent weight, viscosity, and residual monomers. Certificates of Analysis (COA) are available upon request, providing full traceability and assurance of consistent quality for your formulation needs.

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). This material is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and maintain reactivity.
