Q1: What is the CAS Registry Number for JD7098 Hydrofluoroether?
A: The CAS number for JD7098 Hydrofluoroether is 1321375-23-2.
Q2: What is the recommended usage concentration when blended with co-solvents?
A: JD7098 is typically used neat (100%) as a final rinse or carrier fluid; when blended (e.g., with low-boiling alcohols), concentrations of 70–95% v/v are common—always validate compatibility and residue testing per application.
Q3: How does JD7098 compare to HFC-43-10mee or other legacy HFEs in terms of environmental profile?
A: JD7098 offers significantly lower GWP (<15) than HFC-43-10mee (GWP ≈ 1,640) and improved hydrolytic stability versus early-generation linear HFEs, supporting longer bath life and reduced disposal frequency.
Q4: Is JD7098 subject to VOC regulations in the U.S. or EU?
A: No—JD7098 is exempt from U.S. EPA VOC regulations (40 CFR §51.100) and classified as a “zero-VOC” substance under EU Paints Directive (2004/42/EC) due to negligible photochemical reactivity.
Q5: Does JD7098 exhibit migration or extractables risk when in contact with silicone-based gaskets or adhesives?
A: Extensive testing shows no measurable migration or extraction from medical-grade silicones (e.g., Dow Corning® MED-4840) after 72-hour exposure at 25 °C; validated per USP <87> and ISO 10993-12 protocols.
