Quality Control

Our 1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-, Polymer With Methyloxirane is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency and meets agreed-upon specifications for parameters such as hydroxyl value, viscosity, water content, and color. Certificates of Analysis (COA) documenting these results are provided with every shipment. We can support compliance requirements for various industrial standards.

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 material is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and potential oxidation. Keep away from strong oxidizers, acids, and bases.
