The paste has a high viscosityand dries slowly on air. Due to the low melting range the paste is particularly well suitedfor brazing of unalloyed and alloyed steel, copper and copper-plated workpieces aswell as copper- nickel- alloys. Interesting for workpieces that have to be processed at lowtemperatures.Application:Manually or automatically with pneumatical or mechanical dispensing units.
