MG Chemicals 453-NS, Superwick #3 Green, Fine Braid, No Clean, 2.0mm x 50ft, Case of 5
MG Chemicals 453-NS, Superwick #3 Green, Fine Braid, No Clean, 2.0mm x 50ft, Case of 5
MG Chemicals 453-NS No-Clean Superwick is green-coded #3 desoldering braid, 2.0 mm wide, supplied in nominal 50 ft spools. Tightly woven, oxide-free copper coated with high-activation-temperature no-clean flux draws molten solder into the braid for surface solder removal and PCB repair. This listing supplies a case of five spools.
Important packaging distinction: The manufacturer lists the 453-NS 50 ft spool as not ESD safe. Do not apply the ESD-safe claim for the family's smaller bobbins to this package. Select packaging appropriate to your workstation's ESD requirements.
Best Uses / Applications
- Surface solder cleanup during electronics repair and benchtop service.
- Surface-mount touch-up where 2.0 mm braid fits the solder area.
- General-purpose desoldering with a qualified iron-and-braid process.
- Repair operations choosing longer spools instead of 5 ft bobbins, where non-ESD-safe spool packaging is acceptable.
Although the manufacturer overview mentions through-hole repair, its application instructions say braid works best on surface solder and is not recommended for solder inside plated-through holes.
Key Features
- Oxide-free, tightly woven copper for fast wicking and reduced dwell time.
- High-activation-temperature no-clean flux.
- Manufacturer-reported non-conductive, non-corrosive residue.
- Green #3 identification, 2.0 mm width and nominal 50 ft length per spool.
- Case of five spools for replenishing repair benches.

Compare No-Clean Superwick Packages
| Part | Width / color | Length | ESD-safe packaging |
|---|---|---|---|
| 424-NS | 1.5 mm / Yellow | 5 ft | Yes |
| 424-NS-10FT | 1.5 mm / Yellow | 10 ft | Yes |
| 425-NS | 2.0 mm / Green | 5 ft | Yes |
| 453-NS | 2.0 mm / Green | 50 ft | No |
| 426-NS | 2.5 mm / Blue | 5 ft | Yes |
| 426-NS-10FT | 2.5 mm / Blue | 10 ft | Yes |
| 454-NS | 2.5 mm / Blue | 50 ft | No |
Choose width to suit the joint and access. If you need green 2.0 mm braid with ESD-safe bobbin packaging, compare the 5 ft 425-NS rather than assuming the longer spool has the same packaging characteristics.
Use and Residue Management
- Remove conformal coating and contamination from the work area.
- Use an iron temperature 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 apply the iron tip to the braid, avoiding adjacent components.
- When wicking ends, lift the iron and braid together.
- Trim used braid, allow cooling and repeat as required.
- Complete cleaning and inspection according to the assembly process.
No-clean clarification: The manufacturer's introduction says the non-conductive, non-corrosive residue does not need cleaning. However, the same TDS recommends cleaning in its property table and includes removal of accumulated flux in its instructions. Follow your validated 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, provide appropriate ventilation, use protective equipment and review the full SDS before use. Do not use brazing, torch soldering or torch welding methods with this braid. Used braid and solder can remain hot.
Frequently Asked Questions
What size is MG Chemicals 453-NS?
It is green #3 braid, 2.0 mm wide, supplied in nominal 50 ft spools.
How many spools are included?
This listing supplies a case of five 50 ft spools.
Is the 453-NS spool ESD safe?
No. The manufacturer packaging table explicitly lists this 50 ft spool as not ESD safe.
How does 453-NS differ from 425-NS?
Both are green 2.0 mm NS-family braid. 453-NS provides 50 ft on a non-ESD-safe spool; 425-NS provides 5 ft on an ESD-safe bobbin.
Does no-clean mean cleaning is never required?
No. Despite the introductory no-clean statement, the TDS recommends cleaning and includes a cleaning step. Follow the assembly's residue requirements.
Can I use it to clear plated-through holes?
The manufacturer application instructions do not recommend braid for solder inside plated-through holes. It works best on surface solder.
What flux does this braid use?
The TDS identifies high-activation-temperature no-clean flux with R (Rosin), ROL0 classification and less than 5% flux content.
How should it be stored?
Keep it dry at 22–27°C and away from sunlight and moisture. The TDS lists a ten-year shelf life and recommends shrink wrapping for extended storage.
