WIDE COMPATIBILITY - Liquid soldering aid works great in a wide range of applications, including electronics soldering/repair, audio cable connector soldering, PCB soldering, and SMD soldering/desoldering within SMT processes.
User-friendly Design - The high purity organic formula is stable with low volatility. It has a mild, non-irritating smell and contains no lead, halogens or chlorides, making it ideal for longer soldering jobs.
Safe & Reliable Formula - As an RMA (Rosin Mildly Activated) flux, it has a neutral pH and is non-corrosive. High flash point and non-flammability ensure safe storage. The dried rosin residue is non-conductive and provides excellent insulation.
Non-corrosive - #923 is made from high purity rosin. Lead-free, chloride-free, non-toxic, halogen-free, non-flammable and RoHS compliant. Suitable for electronic soldering/repairs. Liquid solder efficiently removes oxides from tin, lead, copper, silver and nickel alloys.
EXCELLENT PERFORMANCE - Lead-free liquid solder provides excellent wettability and efficiently removes oxide layers (for lead-free and lead-free soldering). The liquid flux provides antioxidant effect in various processes such as soldering, desoldering, rework, wave soldering and reflow soldering, resulting in shiny, stable and uniform solder joints.
30 ml squeeze bottle - Easy dispensing of flux by gently squeezing. Includes 2 tapered attachments and a sealing cap for convenient storage after use.

Main highlights

Versatile applications: this product soldering paste has a wide range of applications. It solders flux is suitable for the care of soldering tips, for soldering precision components such as chips in mobile phones and PC cards and also removes excellent oxide layers on gold-copper alloys and wires.
Safe and environmentally friendly: the product solder flux has a creamy, paste-like consistency and is based on natural rosin. This makes it safe and gentle. It soldering flux does not corrode components, offers a high adhesive strength, good wetting and is odourless.
Excellent welding performance: the product solder paste effectively removes the oxide layer on the welding contact surface and thus prevents the secondary oxidation of solder and workpiece during the welding process. At the same time, rosin soldering reduces the surface tension of the solder, making the soldering process smoother and the soldering connection more stable.
Easy to use: Solder flux is quick and easy to use. Clean the area to be soldered before use. Apply solder flux gel evenly to the surface to be soldered, whether it is copper, iron or tin. Various methods are possible, e.g. dotting, painting or applying with a cotton swab. Then solder with a soldering iron, the solder melts and solidifies evenly.
Box contents: you will receive two 50 g cans of the product solder flux. This solder paste flux quantity is sufficient for all common welding work, is economical and economical in consumption. The solder grease flux comes in a sturdy, shock and pressure-resistant box, is well sealed and ideal for travelling.
