ABSTRACT:
A solderable solventless UV curable enamel is disclosed which comprises a totally saturated compound having at least two rings each containing an epoxy group and a UV curative which generates a cation in the presence of UV light. The enamel contains no Lewis base but may contain up to 35% by weight based on total solids of a modifying resin which is co-reactive with the totally saturated compound and which does not char or prevent UV cure. The enamel is suitable for coating wires which must be soldered because the enamel melts away from the solder instead of charring.
