Description

Soldering grease for soft soldering 3.1.1.C / DIN EN 29454-1

Base: Zinc chloride
Form: viscous, yellowish-brown compound
Working temperature range: approx. 150 – 400 °C
Application: Soft soldering flux for copper, copper alloys and zinc surfaces
Includes a robust brush for spreading
Ensures clean and strong solder joints

Soldering grease 621 is ideally suited for preparing copper, copper alloy and zinc surfaces for soldering with common tin solders (e.g. SnCu0.7). The soldering grease removes minor impurities and dissolves oxide layers that would cause insufficiently strong solder joints during soldering. The use of soldering grease is therefore almost essential to ensure good solder joint quality. It can be applied more precisely than soldering fluid because it does not run off. The soldering grease has a corrosive effect after the reaction and must be rinsed off promptly with water or mordant after the soldering process.

During processing, effective extraction / fresh air supply, e.g. by ventilation, must be ensured due to the soldering fumes.

Soldering grease 621 is available in an attractive combination with triangular rods made of Sn99.9 (pure tin), SnCu0.7 or SnCu3.
