Abstract

A flux for forming an adherent, flexible, non-tacky coating on a solder wire consists of an activated polyamide resin or a mixture of a polyamide resin and natural gum or wood rosin in a weight ratio of 1 : 1 to 10 : 1. The polyamide resin is the condensation product of a polyamine e.g. hexamethylene diamine, and a long chain dicarboxylic acid containing 14 to 22 carbon atoms. The activator such as cyclohexylamine hydrobromide, diethyl hydrobromide or cetyl pyridinium bromide is present in an amount of 1%-4% by weight of the resin.
