The flux in the 100g tin from Haupa is a high-quality soldering grease that has been specially developed for soft soldering materials such as tinplate and for tinning copper and brass. It fulfils the DIN EN 29454-1 3.1.1.C standard and is not suitable for applications in electrical engineering or electronics as it contains zinc chloride, which is corrosive. The product is ideal for craft and repair work where a reliable connection between materials is required. The application of the soldering grease ensures improved flowability and a clean solder joint, which increases the quality of the soldered connections. It is important to follow the appropriate safety precautions when using the product as it can cause skin irritation and serious eye damage. The flux is supplied in a convenient can for easy handling.
