Re: epoxy thickener

One good reason I didn t just go to the store and buy powder is that
all I could find was scented.  I can just imagine the inevitable
question from my wife, "Who have you been sailing with?"  Furthermore,
it is fairly expensive.
Sevin dust is fairly cheap and supposedly innocuous to ppl but I didnt
like the idea.  Even considered Ortho fire ant poison (remember, this
is Florida so it makes sense) but it stinks too much.

talc and flour are used as thickenres in resins. the problem with scented
talc is the smell released when sanding. urea formaldehyde adehsive
(plastic resin marine glue) is sold as a powder which includes either
wheat or rye flour as a thickener.

Is this supposed to be a joke? If not, remind me never to board a vessel
that you've built.

I have been working on Minicup #2 but ran out of colloidal silica
epoxy thickener and do not feel like driving all the way across town
to West marine.  So, I recalled some discussions about using talcum
powder or wood flour for this purpose.  First, I used some of my wifes
powder till she found out and blew a gasket over it.  I checked,
powder is expensive, makes the boat smell funny too.  Then, I recalled
cornstarch is used as a thicken er for stews and soups and I had a
little and it worked fairly well.  When it ran out, I used regular
flour, it does not work as well but is ok. I wonder if I could mix a
bug killer like Sevin dust with it to help preserve the wood.
