Engineered for superior wetting and minimal residue, it delivers professional-grade solderability with low spatter and odor. Fully RoHS compliant, this solder is ideal for electronics professionals seeking reliable, eco-conscious performance without the need for post-solder cleaning. ## Description Kester 24-9574-7610 Alloy type: Sn99.3Diameter: 0.020'Flux: 3.3%, No-CleanWeight: 1lb spoolLead content: Lead-FreeHalogen content: Contains Halogen Flux-Cored Solder Wire, No-Clean, Lead-Free, Sn99.3 (K100LD), 3.3%, 0.020', 1lb Spool Kester 275 No-Clean Flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 275 No-Clean Flux results in an extremely clear post-soldering residue without cleaning. The unique chemistry in 275 was also designed to reduce spattering common to most core fluxes. 275 can be used for both lead-free and leaded soldering. 275 is classified as ROL0 per J-STD-004.Performance CharacteristicsColorless translucent residuesImproves wetting performanceExcellent solderability and fast wetting to a variety of surface finishesEliminates the need and expense of cleaningLow smoke and odorLow spatteringCompatible with lead-free and leaded alloysClassified as ROL0 per J-STD-004Compliant to Bellcore GR-78CleaningThe 275 flux residues are non-corrosive, non-conductive and do not require removal in most applications. IPA will not clean the residues off the surface of the circuit board after the soldering process. If removal is required, a saponifier or cleaning agent specifically designed to clean a no-clean flux is required to clean the residues.

Review: Best Lead Free Solder I've found. - Despite all the hype about silver bearing solder even though the silver content is very low, silver bearing solder does not leave a glossy finish even when done correctly but rather a satin finish. Silver bearing solder also shrinks besides looking like a cold joint with lead solder. Kester did their homework with this one. As a diyer I can easily use lead bearing solder, but I want to get used to using lead free as I suspect at some point there will be pressure to take lead bearing solder off the market. To be Rohs compliant commercially you cannot use any lead. ## Features - (1) Kester 24-9574-7610 Spool - 1 LB per Spool - Alloy: K100LD - Lead-Free - Product contains Halogen ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FGHTX5A | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #137,293 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #328 in Solder | | Color | Green Label | | Customer Reviews | 4.7 4.7 out of 5 stars (27) | | Date First Available | September 27, 2013 | | Included Components | 24-9574-7610 | | Item Package Quantity | 1 | | Item Weight | 1.05 pounds | | Item model number | 443-843 | | Manufacturer | Kester | | Material | lead | | Part Number | 443-843 | | Power Source | See Product Details | | Product Dimensions | 2.3 x 2.5 x 2.7 inches | | Size | 1 Pound Spool | | Style | Foldable UV/White Beam | | Usage | Professional | ## Images ![24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy - Image 1](https://m.media-amazon.com/images/I/81+FtGYz3GL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's solder... *by A***R on August 25, 2025* It's solder, it works, not much to review here. ### ⭐⭐⭐⭐⭐ Best Lead Free Solder I've found. *by D***N on September 16, 2018* Despite all the hype about silver bearing solder even though the silver content is very low, silver bearing solder does not leave a glossy finish even when done correctly but rather a satin finish.
