Preparation of an igniter with an ultraviolet cured ignition droplet

A method of making an electrically actuatable igniter comprising the steps of:

• a) providing a body;
• b) locating a pair of electrodes in the body;
• c) electrically connecting a heating element between the electrodes;
• and
• d) adhering a dome shaped ignition droplet to the heating element, the dome shaped ignition droplet prior to being adhered to the heating element comprising an intimate mixture of
• i) a free-radical resin binder which can be at least substantially cured in situ by ultraviolet radiation;
• and
• ii) a particulate pyrotechnic material present in the mixture in a substantial proportion effective for sustained combustion, the pyrotechnic material being ultraviolet radiation absorbing;
• the resin binder prior to adhering the dome shape ignition droplet to the heating element being a liquid and having a surface tension, viscosity, and wettability with the heating element effective to achieve the dome shape.
