Quality Control

Our production of 4,4'-(1-Methylethylidene)Bis-Pheno Polymer With Methyloxirane adheres to stringent quality management systems. Each batch undergoes comprehensive analysis to ensure consistent epoxy equivalent weight (EEW), viscosity, color, and hydrolyzable chloride content, meeting the exacting requirements of advanced polymer applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong alkalis and incompatible organic solvents.
