Here you will find all the frequently asked questions and answers that we have put together for you.
ZINNIN GREEN I Sn100 is lead-free, zinc-free, and complies with the WEEE/RoHS directives. The paste also features a labeling-free formulation and is not classified as a hazardous material. Flux residues are visible under UV light and can be removed with deionized water if necessary. These properties support controlled and efficient application in piping construction.
Before use, stir the paste until the green color of the use indicator changes to a metallic silver-gray and a uniform consistency is achieved. It can then be applied to the parts to be joined using a brush or another suitable tool. Due to the high activity of the flux it contains, the paste spreads well over the surfaces and does not drip.
Before soldering, the surfaces to be joined should be thoroughly cleaned of oxides, dirt, and grease—for example, with a wire brush. Next, a suitable flux is applied. This prevents oxidation during heating and helps ensure that the solder evenly coats the joint.
Emil Otto’s ready-to-use soldering and tinning paste, ZINNIN GREEN I Sn100, is suitable for soft soldering copper tubes and brass fittings. It consists of 100 percent pure tin and is lead-free and zinc-free. In addition to copper and brass alloys, it can also be used for soft soldering and tinning steel and stainless steel.
In addition to protecting against rust and moisture, VO anti-rust oil can lubricate moving parts and protect them from wear. This makes it particularly suitable for providing seasonal protection for machinery and components during extended periods of damp weather.
VO Anti-Rust Oil is suitable for protecting machinery, vehicles, attachments, and tools used outdoors from corrosion. Typical applications include agriculture, highway maintenance, construction equipment, cable cars, and maritime applications.
Rust-preventive oil forms a protective barrier against moisture on metal surfaces, thereby reducing the risk of rust and corrosion. This is particularly important for machinery, vehicles, tools, and attachments that are regularly exposed to rain, snow, or high humidity.
Nitinol is used in numerous military and aerospace applications, particularly where conventional materials reach their limits. These include adaptive structures in UAVs and missiles, thermally controlled actuators and valves, vibration and shock absorption systems, miniaturized microactuators, and reliable separation mechanisms in satellite technology. These applications benefit directly from unique properties such as shape memory and superelasticity.
Even minor deviations in the brazing process can permanently impair the functional properties of nitinol. In particular, the shape memory effect and superelasticity are sensitive to thermal stresses. Therefore, precisely controlled temperature profiles, appropriately selected solder alloys, and suitable fluxes are necessary to preserve the material properties.
A suitable flux must selectively remove the titanium oxide layer, activate surfaces that are difficult to wet, and at the same time minimize corrosive residues. In addition, high process stability, low-residue processing, and suitability for automated manufacturing processes are crucial. Ideally, it should be zinc- and halide-free, non-flammable, and VOC-free.
