MG Chemicals 426-NS-10FT, Superwick #4 Blue, Static Free, No Clean, 2.5mm, 10 ft, Case of 10
MG Chemicals 426-NS-10FT, Superwick #4 Blue, Static Free, No Clean, 2.5mm, 10 ft, Case of 10
MG Chemicals 426-NS-10FT No-Clean Superwick is blue-coded, 2.5 mm desoldering braid supplied on 10 ft ESD-safe bobbins. Its tightly woven, oxide-free copper is coated with high-activation-temperature no-clean flux to draw molten solder into the braid during PCB repair and surface solder cleanup. This listing supplies a case of 10 bobbins. Choose this SKU when you need blue #4 braid in the longer 10 ft format.
Best Uses / Applications
- Surface solder cleanup during PCB repair and benchtop service.
- Surface-mount touch-up where a 2.5 mm braid fits the solder area.
- General-purpose desoldering using a qualified iron-and-braid process.
- Repair stations preferring 10 ft bobbins with ESD-safe packaging.
Application limitation: Although the manufacturer overview mentions through-hole repair, its application instructions say wicking works best for surface solder and is not recommended for solder inside plated-through holes.
Key Features
- Tightly woven, oxide-free copper for fast wicking and reduced dwell time.
- High-activation-temperature no-clean flux.
- Manufacturer-reported non-conductive, non-corrosive residue.
- Blue #4 identification and 2.5 mm width.
- 10 ft ESD-safe bobbin; this packaging claim does not apply to the family's 50 ft spools.

Match braid width to the solder area and access. Select length separately from width and verify the ESD characteristics of the exact package.
Using the Braid and Managing Residue
- Remove conformal coating or contamination from the work area.
- Heat the iron using settings qualified for the assembly. For lead-free solder, the TDS suggests starting at about 315°C and adjusting as necessary.
- Place braid on the solder and the iron tip on the braid without touching adjacent components.
- When wicking ends, lift the iron and braid together.
- Cut off used braid, allow cooling, and repeat as needed.
- Follow the assembly's residue-cleaning and inspection requirements.
Cleaning clarification: The manufacturer's introduction describes the non-conductive, non-corrosive residue as not needing cleaning. However, the same TDS recommends cleaning in its property table and includes removal of accumulated flux in its instructions. Follow the validated assembly process rather than treating “no-clean” as a universal instruction to leave residue.
Safety and Handling
The SDS identifies rosin-related respiratory and skin sensitization hazards. Avoid breathing fumes, use appropriate ventilation and protective equipment, and review the complete SDS before use. Do not use brazing, torch soldering or torch welding methods with this braid. Used braid and solder may remain hot.
Frequently Asked Questions
How does 426-NS-10FT differ from 426-NS?
Both are blue 2.5 mm No-Clean Superwick. This SKU contains a nominal 10 ft per bobbin rather than the standard 5 ft.
How many bobbins are included?
This listing supplies a case of 10 bobbins, each with a nominal 10 ft length.
Is this 10 ft bobbin ESD safe?
Yes. The current manufacturer packaging table explicitly marks 426-NS-10FT as ESD safe. Maintain normal workstation ESD controls.
What width is the braid?
It is 2.5 mm wide, blue-coded #4, with a manufacturer nominal imperial width of 0.10 in.
Does no-clean mean residue removal is never needed?
No universal rule should be assumed. The TDS describes non-conductive, non-corrosive residue but also recommends cleaning and includes a cleaning step. Follow the assembly's requirements.
Can it clear plated-through holes?
The manufacturer's application instructions do not recommend braid for solder inside plated-through holes. It works best on surface solder.
Are all NS-family spools ESD safe?
No. The packaging table marks 453-NS and 454-NS 50 ft spools as not ESD safe. Use the characteristics of the exact SKU.
What is the shelf life?
The TDS lists ten years with appropriate storage. Keep dry and away from moisture and sunlight; shrink wrapping is recommended for extended storage.
