<DIV><SPAN class=268512915-06092002><FONT face=Arial color=#0000ff size=2>So
does micro-balloon expoxy mixtures have any structural strength? I have both
micro-balloons and cabosil - and I'm never quite sure when I should use one as
opposed to the other. I generally reserve the cabosil when I just want to
thicken epoxy into a paste, and weight isn't a huge issue. How do you decide
which one to use for a particular application?</FONT></SPAN></DIV>

<DIV><FONT size=4>Cabosil is fumed silica sand. It's extremely light weight.
When mixed with epoxy finishing resin, it creates a paste that won't run on
vertical surfaces. It's also frequently mixed with epoxy in a thinner mix and
brushed into a mold to create the external gel coat on a glass part which
prevents pinholes from making it to the surface of a part. On a clear
epoxy-cloth piece, the epoxy/cabosil mix can be seen in all the 90-degree
corners to bridge the radius the cloth can't make. It'll show as an opaque
white as opposed to the clear epoxy/cloth you see everywhere else. Down side
is that it's much tougher to sand than micro-balloons and has virtually no
structural strength. Good stuff to have around, though. I use it a
lot.</FONT></DIV>
