Abstract:
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; andd) 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 ofi) a free-radical resin binder which can be at least substantially cured in situ by ultraviolet radiation; andii) 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.
