Quality Control

Our production of Phenol, Polymer With 3A,4,7,7A-Tetrahydro-4,7-Methano-1H-Indene, Cyanate adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as cyanate equivalent weight, viscosity, and thermal properties are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing purity, functional group content, and physical specifications is provided with every shipment to support your quality assurance processes.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and incompatible materials.
