PROTINFLUX 1001 has a great pickling power. Its wettability is excellent; the eutectic is minimised as much as possible. The flux is stable at high temperature, even with flame heating.
PROTINFLUX 1001 is highly concentrated, is safe to use and generates good cost savings.
PROTINFLUX 1001 has the following specific composition:
PROTINFLUX 1001 is intended for the preparation of copper alloys for brazing processes using lead/tin, tin/copper or tin/silver (low silver content, usually 3,5%) filler metals.
The parts are fluxed by dipping, spraying or hand brushing.
The brazing is done either in a furnace, by torch soldering or by dipping in a tinning bath.
The control of the fluxing bath is done by checking its density.
The brazing is followed by rinsing in water and then washing with hydrochloric acid to remove any residual salt which could cause corrosion.
