Abstract

This compound is a soldering flux which is soluble in water or alcohol. The compound acts as both an activator to reduce the oxide layer of the metal surfaces to be soldered and as a protector to prevent re-oxidation of the metals during soldering.

Water Soluble Soldering Flux

This compound is a soldering flux which is soluble in water or alcohol. The compound acts as both an activator to reduce the oxide layer of the metal surfaces to be soldered and as a protector to prevent re-oxidation of the metals during soldering.

The compound, Poly-N Diethanol Diammonium Ethyl Ether, is classed as a quaternary ammonium salt condensation polymer with the following probable structure:

(Image Omitted)

It is a highly viscous semi-solid very soluble in water or alcohol. It is produced by reacting 22' dichloroethyl ether and diethanolamine in equal molecular proportions at between 110 to 125 degrees C.

The flux is used directly in either a diluted or undiluted form in dip soldering or hand soldering operations. By virtue of its water solubility, it substantially simplifies the excess flux removing operation after soldering.
