Frequently Asked Questions (FAQ)
Its primary function is as a high-performance, eco-friendly solvent and hardening agent. Its largest application is in the foundry industry for the cold-box core-making process, where it acts as a curing agent for phenolic resins. It is also widely used as a solvent in coatings, inks, and industrial cleaning formulations.
The unique Chemical Abstracts Service (CAS) registry number for ethylene glycol diformate is 629-15-2. This number is used globally to identify the substance unambiguously in regulations, safety data sheets, and scientific literature.
Both are formate esters with similar functions, but they have different properties. Ethylene glycol diformate (EGDF) has a lower molecular weight and boiling point (174°C) compared to diethylene glycol diformate (DEGDF, ~220°C). This means EGDF has a slightly faster evaporation rate and curing speed, making it suitable for processes requiring quicker setting times. DEGDF, with its slower evaporation, is ideal for applications needing longer open times or higher temperature stability. We can help you select the right one or a blend for your specific needs.
It should be stored in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and strong oxidizing agents. Keep container111s tightly sealed to prevent moisture absorption, which can lead to hydrolysis. Standard personal protective equipment (PPE) such as safety glasses, gloves, and appropriate clothing should be worn during handling, as outlined in the Safety Data Sheet (SDS).
Yes, it is considered an environmentally friendly or "green" solvent. It is readily biodegradable, meaning microorganisms can break it down quickly in the environment.
