Cabosil Suplier???

Bryan A. · #1 03-21-2006, 09:09 PM

Any one have a good source for Cabosil (Coloidal Silica) either near my location or online? I need to buy a fair amount,(yet to be determined) and I refuse to bend over at West marine or the like.

Find out where the local fiberglass guys buy their materials - and buy it there - that's what I did. MUCH cheaper - I bought all my stuff from suppliers like that. i.e. Five gallon bucket of quality resin w/ catalyst - $75 !

Bryan How much do you want? [in volume] I have a 30lb dog food size bag of it. I'll sell you some.

I have sourced

a supplier at $78.00 for a ten pound bag, can you beat that? I can't believe you would want to get rid of any. No more future projects?

I doubt I will need ten pounds now but it won't go bad and I know I will use the stuff for other projects down the line.

Bryan-

Have you tried LBI Fiberglass up in Groton?

I do not know their price but know they have it in bulk.

10lb's would be a 30lb dog food size bag. What in the world would you do with that mutch?

Certinally not for fairing.

I have just about stopped using it all together. Unstaed I use FGCI's 2 to 1 epoxy bonding putty.

I do use a little Cabisol now and then. If I'm spot welding something together. I'll add a little to some 5min epoxy to thicken it up so it doesn't run. then I'll come back and run my fillet's in the Bonding putty right over those spot's.

Trayder - I have not tried them yet but thank you for reminding me they are there. I will check

No I will not be using the whole10 lbs for my current project but I would like to have it around for future projects, wishful thinking. Its the whole buy in bulk theory, You know you buy 30 lbs. of Goldfish crackers at the wholesale price because it is cheaper then when you get home you realize you bought 30lbs of goldfish crackers.
I am realy not sure how much I need at this point.

Wart - What's the advantage of the bonding putty? Less mixing, or air intrusion?

BOTH.

For mixing large quantities of Cabosil, I went to Home Depot and purchesed 1 & 2 gallon plastic buckets with lids. I cut a small hole in the lid to accept my paint mixer. This keep the dust inside the bucket and got pretty good consistancy.

Sounds like you've received lots of advice, but I'll add my two cents. I use Cabosil grade PTG in my business and we buy through a distributor, Mozel Inc. 800-950-5670. The Aerosil product is made by Degussa Corporation and I'm sure you could find a source for it on the intenet. Good Luck.
