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 Characteristics:Low spatteringLow smoke and odorColorless translucent residuesExcellent solderability and fast wetting to a variety of surface finishesClassified as ROL0 per J-STD-004BCompliant 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.SpecificationsWire Diameter: 0.020 in (0.50 mm)Alloy Name: K100LDFlux %: 3.3 %Flux Type: No CleanLead Free: YesHalogen Content: HalogenSeries: 275 SeriesAlternate Product Number: K100LD, 2495747610Alloy Type: Eutectic AlloysComposition: 99.3% Tin, 0.7% CopperCore Size: 66Liquidus Point: 229 C (444 F)Melting Point: 227 C (441 F)Melting Range: 227-229 C (441-444 F)Package Type: SpoolShelf Life: 1095 daysWeight: 1 lb (0. ## Features - Wire Diameter: 0.020 in (0.50 mm) - Alloy Name: K100LD - Flux %: 3.3 % - Flux Type: No Clean - Lead Free: Yes ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00FGHTX5A | | Best Sellers Rank | #155,899 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #331 in Solder, Solder Fluxes & Pastes #466 in Welding Accessories | | Item Model Number | 443-843 | | Manufacturer | Kester | | Product Dimensions | 5.84 x 6.35 x 6.86 cm; 476.27 g | ## Images ![Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.50cm Diameter-Low Cost Alloy - Image 1](https://m.media-amazon.com/images/I/81+FtGYz3GL.jpg) ![Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.50cm Diameter-Low Cost Alloy - Image 2](https://m.media-amazon.com/images/I/81B09qc8PPL.jpg) ![Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.50cm Diameter-Low Cost Alloy - Image 3](https://m.media-amazon.com/images/I/81k9m+QTnWL.jpg) ## Frequently Bought Together - Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy - Kester443-845 24-9574-7618 K100Ld Lead-Free No Clean Wire Solder.031" Diameter-Low Cost Alloy - Thermaltronics TMT-TC-2 Tip Tinner (20g) in 0.8oz Container --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/335345620-kester-24-9574-7610-k100ld-lead-free-no-clean-wire](https://www.desertcart.us/products/335345620-kester-24-9574-7610-k100ld-lead-free-no-clean-wire) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-24*
