dangerousamateur Posted August 22, 2012 Share Posted August 22, 2012 Hi, when preparing a few little whistle inserts I got hot hotglue touching whistle mix (with catalyst & vaseline, leftover from rocket production) multiple times. Yes, the gun was unplugged. It gives me an uneasy feeling though. How dangerous is it actually? Link to comment Share on other sites More sharing options...
dagabu Posted August 22, 2012 Share Posted August 22, 2012 Not very dangerous at all but I would do what I could to avoid it. -dag Link to comment Share on other sites More sharing options...
xBangergoosEx Posted August 22, 2012 Share Posted August 22, 2012 Generally speaking, hot glue guns are not hot enough to ignite pyrotechnic compositions. The hottest i have ever seen the glue get is 380*F, which isnt hot enough to ignite black powder, flash powder, etc. However i would be careful about touching the metal nozzle of the glue gun to any comps, just to be safe.

Mumbles Posted August 22, 2012 Share Posted August 22, 2012 Just out of curiosity, where does hot glue come into play when making whistle inserts? Link to comment Share on other sites More sharing options...
dagabu Posted August 23, 2012 Share Posted August 23, 2012 Good question, I just wipe a layer of wood glue over the exposed whistle after pressing them. -dag Link to comment Share on other sites More sharing options...

Is it a way to protect the whistle grain? Haven't progressed to the point of playing with whistle yet, but I'm still sponging up whatever information I can get Link to comment Share on other sites More sharing options...

Now, a lot of people use a small report at the end of the whistle and then a paper disk and hot glue are used to seal it up. -dag Link to comment Share on other sites More sharing options...

A similar situation happens when I fix the fuse to my small whistle rocket engines. The hotglue is a low temp type.
