I took somewhat of a deep dive into this topic and looked at numerous products last year. 

You may also want to consider :

	>Dymax#9451

	> Peters SL1347(black)  and SL1397 (white)

I also observed that those which have  some degree of filler content performed best as a security coating, however I doubt you will find that these lend themselves to a dip process. Those mentioned above do not have any filler.

Hello Technet



So I've got a customer who wants to dip coat their circuit board.  It is a small thing, 1/2" x 2", with wires attached at one end.  So for dip coating I can actually hang it by the wires for curing, no masking required - works out OK.



A couple of questions though.



1) any gotcha's with dip coating?  I've only done spray (manual and

automated) thus far.  Is viscosity critical?



2) does anyone make a black colored coating? They are somewhat concerned with IP protection so a color block would be a plus.



Happy labor day weekend to all on this side of the pond!



thanks,
