Thermal curing induces chemical crosslinking to form stable films, offering good chemical & physical resistance. XZ253 is able to withstand normal PCB fabrication without loss of sheet resistance. Fully cured prints will resist most chemicals, mass soldering techniques and flux removal systems associated with the manufacture of a printed circuit board and cleaning operations.

The recommended curing cycle is 60 minutes at 150 ° C (302 ° F). Lower cures are possible but will result in a reduced solvent rub resistance.

Normally used for printing conductive tracks, crossovers and also for printing through holes. It is possible to print additive circuitry in place of etched copper.

It has also under gone limited beta testing as conductive hole plug and conductive through hole ink with success at customers in small scale testing.
