Cabosil silica epoxy thickener is for use when an extremely hard solid with high density is needed, i.e. structural bonding, filling and filleting. Can be used alone for a very smooth finish or in conjunction with chopped fiberglass.
Often times, cabosil is used to moderate the viscosity of the epoxy and is added in addition to other epoxy fillers. Silica thickener is similar to WEST Systems 406 Colloidal Silica.

2012-02-06STEPHEN RICHMAN: I have not used the Cabosil product but have used both the Jamestown and MAS fused silica and found them to be virtually the same.

2012-01-17DANIEL CAOUETTE: No but...
The product is fumed silica, the main component of glass. In other words: it's very, very fine glass. It has particle size of 5รข??50 nm. Fumed silica is not listed as a carcinogen by OSHA, IARC, or NTP. Due to its fineness and thinness, fumed silica can easily become airborne, making it an inhalation risk, capable of causing irritation. Wear a dust mask.
2012-01-17BRIAN CURTISS: The MSDS sheet has rated this materials HEALTH at 1, witch means, a slight hazard- irritation or minor reversible injury is possible.
It should be treated as a nuance dust.
2012-01-17WILLIAM BROADLEY: always wear a mask....
2012-01-17KARL NISSON: The best answer to this question is:
GOOGLE Cab-o-sil MSDS. (Material Safety Data Sheet)
If you have a question about any product the MSDS will answer your question.
2012-01-18DALE QUAKENBUSH: I don't think so. It is very fine and floats in the air so I wera a dust mask.
2012-01-18TERRY DUVIEILH: I have used the product a few times for thickening epoxy and polyester resins and have not had any problems with skin or eye irritation when handling it. In its raw state, its very light and fluffy. It will get into the air and generate a lot of dust when you are mixing or otherwise handling it. As always, use protective gear. A quick web-search will find MSDS sheets and other data for almost any material. This material appears to be widely used in consumer products like shampoo, soaps, and even medications so it would seem to be non-toxic.

2012-01-06CHRIS CRANDALL: No, no, a thousand times, no. Your real issue is what resin/glue? But frankly, a trip to the junkyard should be in your future.

2011-09-21LARRY BLACK: I've had good luck mixing it as a strengthener and thickener with Mas Epoxy. It does not cure clear but a little bit white. There need be no other additive.
2011-09-21ROBERT MCGAHA: Paul, I'm assuming by your question you mean "can I add it to the fiberglass resin by itself?" and the answer is yes. You do not necessarily have to add any additional fiber filler or chopped glass ect. to your resin to use this thickener. I have used it with and without additional fillers. depending on what the objective was. The main reason I use Silica Cab-o-sil Thickener is in basically when glueing surfaces together so that the resin doesn't run out of the joint or if I'm fiberglassing something whether flat or on a slope to help minimize the resin from running. My experiance has also been that when using thickener that your work time shortens.
2011-09-21CHRIS CRANDALL: Can't imagine why. Its primary purpose is to thicken another liquid or gel (or to turn a liquid into a gel). If used "by itself" it will just blow away.
2011-09-21SETH WOOD: If you mean: can it be added to epoxy as the only thickener, then yes. It creates a very strong and tough adhesive, much stronger than just the resin/hardener mix, which should not be used as adhesive unless you add something to it. Like this silica powder.
2011-09-21JOHN LAUPHEIMER: Silica Cab-o-sil Thickener is used to thicken epoxy to give it thixotropic properties (meaning it stays where you put it) and to make the epoxy gap filling. It is mixed into any of the major manufacturers generic epoxy to create a glue or a fillet paste. You use less for a glue and more for fillets. The epoxy is mixed first according to the manufacturer's instructions. Often the surfaces are wetted out with this relatively thin liquid and then the silica is added to the pot of mixed epoxy. This is then spread on one surface or into the fillet area.. The stuff is bad for your lungs so wear a respirator or a dust mask.
2011-09-21KEVIN MATKOSKI: By itself? No. It is a poweder of very fine glass particles. It could almost be classified as a dust. Don't use it in an open environment where ther is a breeze.
If you mean, can be used as the only additive to your epoxy mix... then yes. I start with a tablespoon of Cab-o-sil per pump of resin. This way you can keep it ready for use. Then add hardener. If it's too thin, just add more cab-o-sil.
As a side note, I have not had any problems using just cab-o-sil, but the dried resin is very hard. I add some microbaloons to make it more sandable.
2011-09-21BARRY CUNNINGHAM: If you mean can it be used alone to thicken your epoxy, absolutely. Here's what i've learned working with this product: 1) mix your resin and hardener thourghly first 2) careful where you pour in the silica - it's very light so if there's any wind it'll fly all over. Not good stuff to be breathing either 3) it's as hard (or harder) to sand than the epoxy when it's cured. If you are using it to fair, better to take a look at the micro ballon fillers made for sanding.
It leaves the epoxy milky when it cures, but it's a great solution for all sorts of structural type aplications. I've mixed it as thick as peanut butter and filled joints overhead with success - good luck!
2011-09-21THOMAS RITZLER: no... this product is meant to be used with an epoxy product as a thickener
to add viscosity and strength to your project
its liek super fine ground consistency
and your should always wear a mask and in low wind conditions
don't ask me how i know that :)
hope this helps
2011-09-21JACK HOBSON-DUPONT: Maybe I misunderstand your question. How would you use Cab-O-Sil by itself? It's an extremely light, flaky, powdery substance that would just blow away by itself. It needs to be added to a liquid, to make the liquid more viscous.
2011-09-21TED DWYER: I have used this product many times to thicken MAS epoxy. It does a great job of allowing me to fill voids and create smooth fillets with no mess and no drips. It is EXTREMELY fine powder. I would not go near an open container of it without a mask, the smallest breeze will send it into the air.

I used this to thicken epoxy resin for laminating material to the inside of a fiberglass T bucket body so as to be able to cut a door in.

Comments about System Three Silica Cab-o-sil Thickener:
I purchased this product to thicken epoxy for gluing wood together. I am building a Guideboat and many joints are vertical, this product does well to thicken the epoxy and keep it from running. It is very light and fluffy, so when scooping it out of the container it is likely you will loose some as it 'poofs' out.
