Hi,
I have recently started dipping my own igniters. I have been using daveyfire or similar low curent electic matche and dipping it in pyrogen, but realized how fragile the cured pyrogen is.
Does anyone have any easy suggestions of how to protect the pyrogen from cracking?
I have heard that you can dip them in lacquer but wasnt sure what kind to buy. I tryed dipping them in slow curring epoxy after the pyrogen had cured for a few hours. I decided to test them in my back yard using a 9Vt battery, (I will be using an altimeter to set off the e-matches) and found that the electric match popped, but the pyrogen remained. I am 100% sure that the epoxy was what kept the igniters from lighting because I have used these dipped igniters the same way, but without them being dipped in epoxy.
Thanks for your help,
Tom Sak
