The Metallic H3™ has a low enough ignition point to be used by itself on the element wire with no primer, however, it can be used as a secondary coat as well. It has a brilliant display of sparks when it fires for positive ignition of the application. As with all our pyrogen kits, they come complete with adhesive, oxidizer and instructions. Why pay over $1.50 each for commercial igniters? We recommend our Firefox Custom Chips (Stock# F515F 47 awg for best ignition). KIT MAKES UP TO 500 IGNITERS! Non-hazmat shipping - No ATFE required to order.
