Re: TC Secondary Electrostatic Charge


Mark and Malcolm,

Hot glue is an ultralow density polyethylene accroding to our plastics guru 
and phyicist, Kim Goins.  I have used it for years in holding a lot of coil 
related material together.  Like mark, I have long used it to coat or "pot" 
my RF core chokes.  On the big magnifier, my giant RF toroidal chokes are 
coated as well and after many minutes of firing it has all melted off as the 
chokes attain high temperatures.  This proves that they are workin' guys! 
 All the Rf at 6-8KW normal magnifier run power is, indeed, being trapped in 
them!  They are too hot to touch after a 5 minute continous run at 8 KW.

Hello Malcolm and others,
        The glue sticks appear to be mostly low density polyethylene, based
on what I have been able to determine.  I coat my iron powder chokes
completely in hot-melt glue after they are wound with wire.  It has greatly
reduced arcing problems I was having with the chokes.
