Re: [Killietalk] Acrylic bonding

Hi Al,  The higher the number, the thicker the product is true to 
a certain extent. 3 is very fast setting, 4 is moderately fast setting, 
and 5 is slow setting. I think you can pick the setting speed based 
on air temp. I looked on their website, and they don't even list 
a 10 anymore, and I could swear that was the stuff that was like 
honey. However, 40 is not extra thick (as the high number would 
make you believe), it is water thin, but it is a 2 part product, 
and makes incredibly strong joints.   I think you can also use a 
router bit held in your hand for cleaning up cut edges, but I haven't 
tried it. I might though, because I have a ~90g compartmentalized 
(is that a word?:) tank that has a side coming apart and needs re-welding. 
This thing is 6 ft. long and isabout a foot high and 2 feet wide, 
with 8 compartments and then a 2x2 foot open area at one end. The 
dividers are slid down into slits in the top, and can be pulled 
for making larger compartments.  Each compartment has i
t's own top that can be lifted off. It's a pretty cool unit.  Ron
PS. Good info on working with acrylics.
