Castolin 157 PA Solder paste

Dispensable solder paste for iron and copper materials

Castolin 157 PA

Ready-to-use, dosable binder suspension made of fine-grained tin-silver-based soft solder powder with flux components in an optimum mixing ratio.
The paste is intended for manual and mechanized processing. Due to its precisely defined viscosity and homogeneous consistency, it is particularly suitable for series production with automated dosing equipment. Excellent wetting and flow properties. Suitable for the food industry and medical technology, as it is free from cadmium, lead, zinc and antimony. Tight, clean seams without rework. High-strength solder joints. Cold-resistant down to - 200 °C.
