For formulators working with epoxy resin systems, a deep understanding of the technical specifications of their raw materials is crucial for achieving optimal performance and predictability. This article serves as a technical guide to 2-Ethyl-4-methylimidazole (CAS 931-36-2), detailing its key characteristics and providing insights for formulators looking to purchase this essential curing agent. We, as a dedicated manufacturer and supplier, aim to provide clarity on these critical aspects.

Appearance: Industrial-grade 2-Ethyl-4-methylimidazole is typically described as a pale yellow to reddish-brown viscous liquid. Variations in color and viscosity can sometimes be indicative of minor impurities or storage conditions, highlighting the importance of sourcing from reliable suppliers who maintain strict quality control. Our product consistently meets high standards for appearance, ensuring predictability in your formulations.

Assay/Purity: The purity of 2-Ethyl-4-methylimidazole is commonly specified as a minimum of 95.0% (often determined by Gas Chromatography, G.C.). Higher purity levels can lead to more predictable reaction kinetics and better final properties in the cured epoxy resin. Formulators should always refer to the Certificate of Analysis (COA) provided by the supplier to confirm the exact purity and impurity profile. As a leading manufacturer, we ensure our product exceeds industry standards.

Molecular Formula and Weight: The molecular formula is C6H10N2, with a molecular weight of approximately 110.16. This information is fundamental for stoichiometric calculations in epoxy formulations.

Usage and Handling: 2-Ethyl-4-methylimidazole is primarily used as a curing agent or accelerator in epoxy resin systems, including adhesives, coatings, casting, encapsulation, and composites. It is soluble in water and most organic solvents, and it is alkaline. Proper storage is essential; it should be kept in a dry, well-sealed container away from direct sunlight and heat to prevent moisture absorption or degradation. We advise users to consult the Material Safety Data Sheet (MSDS) for detailed handling and safety precautions.

When considering where to buy this chemical, prioritizing suppliers who provide detailed technical specifications and maintain consistent quality is key. Understanding these specifications allows formulators to fine-tune their recipes, predict curing behavior, and achieve the desired performance characteristics in their final products. We are committed to being your trusted supplier for high-quality 2-Ethyl-4-methylimidazole.
