MG Chemicals 442, Superwick #2 Yellow, Fine Braid, 1.5mm x 25ft, Case of 5

MG Chemicals 442 Superwick Fine Braid is yellow-coded #2 desoldering braid, 1.5 mm wide, supplied in nominal 25 ft spools. Its tightly woven, oxide-free copper is coated with RMA flux for fast solder uptake during PCB repair and surface solder cleanup, helping minimize dwell time. This listing supplies a case of five spools.

Packaging distinction: The manufacturer's packaging table lists the 442 25 ft spool as not ESD safe. The standard family's ESD-safe bobbin claim applies to its 5 ft sizes, not this spool. Select packaging appropriate to your workstation requirements.

Best Uses / Applications

Surface solder removal during PCB rework and repair.
Benchtop electronics service and surface-mount assembly touch-up.
Work where narrow 1.5 mm braid fits the solder area and adjacent-component clearance.
Repair operations choosing 25 ft spools where non-ESD-safe packaging is acceptable.

Application limitation: 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

Tightly woven, oxide-free copper for fast wicking and reduced dwell time.
RMA flux coating, distinct from the separately documented NS and LF families.
Manufacturer-reported non-corrosive residue; cleaning recommended.
Yellow #2 identification and nominal 25 ft length per spool.
Economical fine-braid format, as described by the manufacturer.

Flux classification, TDS	R (Rosin), ROL0
Flux percentage, TDS	Less than 5%
Residue	Non-corrosive, manufacturer reported
Cleaning	Recommended
Shelf life	10 years
Storage	22–27°C, dry and away from sunlight and moisture; shrink wrapping recommended for extended storage
Manufacturer listing	TDS identifies the family as NSF Nonfood Compounds Program listed
Documents	TDS September 10, 2025; SDS September 25, 2025, version 5.00

The SDS composition table reports 95% copper and 5% rosin by weight; the TDS separately reports flux content as less than 5%. These are the respective document statements, not a new measured composition claim.

Compare Standard RMA Superwick Sizes

Part	Width / color	Length	ESD-safe packaging
423	1.0 mm / White	5 ft	Yes
424	1.5 mm / Yellow	5 ft	Yes
442	1.5 mm / Yellow	25 ft	No
452	1.5 mm / Yellow	50 ft	No
425	2.0 mm / Green	5 ft	Yes
443	2.0 mm / Green	25 ft	No
453	2.0 mm / Green	50 ft	No
426	2.5 mm / Blue	5 ft	Yes
444	2.5 mm / Blue	25 ft	No
454	2.5 mm / Blue	50 ft	No
427	3.0 mm / Brown	5 ft	Yes

These are standard RMA-family part numbers without an NS or LF suffix. Choose width to fit the solder area, then select length and packaging separately. For yellow braid with an ESD-safe bobbin, compare the standard 5 ft 424.

Application and Cleaning Guidance

Remove conformal coating or contamination from the work area.
Use a soldering-iron temperature qualified for the assembly. For lead-free solder, the TDS suggests starting at about 315°C and adjusting as needed.
If appropriate, apply compatible flux to the lead or land area.
Place braid on the solder and the iron tip on the braid, avoiding other components.
When wicking ends, remove iron and braid together.
Trim the used section, allow the area to cool and repeat as needed.
Clean accumulated flux residue with an appropriate flux remover and inspect according to the assembly process.

The TDS names MG 4140, 4140A, 4050A and 413B as example flux removers. Confirm material compatibility and follow the selected cleaner's instructions before use.

Safety and Handling

The SDS identifies rosin-related respiratory and skin sensitization hazards. Avoid breathing fumes, use appropriate ventilation and protective gloves, and follow the full SDS, including respiratory-protection guidance where ventilation is inadequate. Do not use high-temperature torch soldering, torch welding or brazing methods. Used braid and solder can remain hot.

Frequently Asked Questions

What size is MG Chemicals 442?

It is yellow #2 braid, 1.5 mm wide, supplied in nominal 25 ft spools.

How many spools are included?

This listing supplies a case of five 25 ft spools.

Is the spool ESD safe?

No. The manufacturer's packaging table marks the 25 ft 442 spool as not ESD safe.

Is this no-clean braid?

No. 442 belongs to the standard RMA Superwick family. Use its own documents rather than the NS or LF family sheets.

Should the residue be cleaned?

The TDS recommends cleaning and includes removal of accumulated flux residue in its instructions.

Can it clear solder inside plated-through holes?

The manufacturer application instructions do not recommend this method for solder inside plated-through holes. Braid works best on surface solder.

How does 442 differ from 424 and 452?

All three are yellow 1.5 mm standard RMA braid. 424 provides 5 ft on an ESD-safe bobbin; 442 provides 25 ft and 452 provides 50 ft, both on non-ESD-safe spools.

How long can it be stored?

The TDS lists a ten-year shelf life with appropriate storage. Keep dry at 22–27°C, away from sunlight and moisture; shrink wrapping is recommended for extended storage.
