Semiconductor Cleaning Agent | HCFC-141B Replacement | HCFO-1233zd(Z) | CAS 99728-16-2
HCFO-1233zd(Z) Precision Cleaning Fluid
HCFO-1233zd(Z) (CAS 99728-16-2), chemically known as (Z)-1-Chloro-3,3,3-trifluoropropene, is a next-generation precision cleaning agent developed for the semiconductor, electronics, and aerospace industries. As global regulations tighten on HCFCs (like 141B) and HFCs, this product stands out with its Zero Ozone Depletion Potential (ODP) and Ultra-low Global Warming Potential (GWP < 1). With a moderate boiling point of 39.0°C and a KB value of 34, it provides powerful solvency while ensuring rapid, streak-free drying.

Q: What is the difference between 1233zd(Z) and 1233zd(E)?
A: 1233zd(E) boils at ~19°C (gas at room temp), while the Z-isomer boils at 39°C. This makes the Z-isomer a stable liquid at room temperature, ideal for immersion cleaning and vapor degreasing.
Q: Is it compatible with sensitive plastics?
A: It is compatible with most materials like PTFE, PP, and PE. For sensitive resins like Polycarbonate (PC) or ABS, we recommend a small-scale compatibility test before full implementation.
Q: Why is it the best 141B replacement?
A: It matches the cleaning power (solvency) of 141B while being non-flammable and having near-zero impact on the ozone layer and global warming.
