Indium Tacflux 089HF 10CC Syringe
Indium TACFlux 089HF — No-Clean Halogen-Free Solder Flux, 10cc Syringe (FLUXOT-84500-10CC)
Indium TACFlux® 089HF (part number FLUXOT-84500-10CC) is a no-clean, halogen-free solder flux formulated for SnAgCu (SAC) and SnAg lead-free soldering processes. Also compatible with SnPb solder, TACFlux 089HF provides excellent wetting performance in both air and nitrogen atmospheres. Both the flux and flux residue are halogen-free, meeting the requirements for halogen-free electronics assembly. Supplied in a 10cc syringe for precision dispensing in hand soldering, rework, and selective soldering applications.

Frequently Asked Questions
What is the difference between TACFlux 089HF and TACFlux 020B?
Both are no-clean, halogen-free fluxes from Indium Corporation, but they are optimized for different applications. TACFlux 089HF is specifically formulated for SnAgCu (SAC) and SnAg lead-free alloys with excellent wetting in air or nitrogen, making it well-suited for nitrogen-atmosphere selective soldering. TACFlux 020B is a broader-use no-clean flux for both SnPb and Pb-free processes. Contact MTE Solutions to select the right flux for your specific process.
Is TACFlux 089HF compatible with SnPb solder?
Yes — while TACFlux 089HF is optimized for SAC and SnAg lead-free alloys, it is also compatible with SnPb (tin-lead) solder. This makes it useful in mixed-alloy rework environments where both lead-free and SnPb soldering occur.
Does TACFlux 089HF work in nitrogen atmosphere soldering?
Yes — TACFlux 089HF provides excellent wetting performance in both air and nitrogen atmospheres, making it suitable for nitrogen-blanketed selective soldering systems where reduced oxidation is required for improved joint quality on difficult-to-wet surfaces.
Is the flux residue from TACFlux 089HF halogen-free?
Yes — both the flux itself and the post-solder residue are halogen-free, meeting IPC J-STD-004 halogen-free classification requirements. This is important for applications where halogen content in residues must be minimized for reliability or environmental compliance reasons.
What is the 10cc syringe format used for?
The 10cc syringe (FLUXOT-84500-10CC) is designed for precision manual dispensing in hand soldering, rework, and selective soldering applications. It allows operators to apply a controlled, targeted amount of flux directly to the joint or pad without contaminating surrounding areas or components.
