CastoTin II soft solder paste

CastoTin Il

Ready-to-use/lead-free solder paste based on pure tin. Excellent wetting properties. Low-viscosity solder with good capillary properties. Suitable for the food industry and medical technology, as it is free from lead, cadmium, zinc and antimony. Tight, clean seams without reworking. Corrosion-resistant joints and coatings.

APPLICATIONS
For gap and build-up soldering, e.g:
Unalloyed and low-alloy steels (structural steels, galvanized steels and sheets, case-hardening and heat-treatable steels), high-alloy steels (stainless CrNi steels), malleable cast iron, copper (SF-Cu), brass (CuZn alloys), tombac (low-Zn brass materials), bronze (CuSn alloys), gunmetal (CuZnSnPb alloys), nickel silver (CuNiZn alloys), copper-nickel alloys, nickel, nickel alloys and fine zinc.

Typical applications are
Vessels and appliances in the food industry, household items, floats, measuring, control and shut-off fittings, refrigeration and air conditioning systems, the lamp industry, electrical contacts and optical, precision mechanical and surgical instruments.

PROCESSING INSTRUCTIONS
Clean soldering areas. Round off edges. Mix well before use. If necessary, moisten/dilute solder paste with clean, lime-free water or flux 157 in a separate glass container. Coat soldering surfaces with solder paste.
Preheat the workpiece widely and thoroughly. Do not overheat. Remove corrosive flux residues with warm water.
Heat sources: Flame soldering (acetylene), flame soldering propane/butane), solder bath soldering, piston soldering, HF induction, resistance heating.

Delivery form
Standard: 0.5 kg, solder paste
