What is CAB-O-SIL used for?
CAB-O-SIL fumed silica performs well in a range of base oils and is widely used in dielectric greases, damping greases, vacuum greases and food grade greases. The use of lubricating greases is essential across a wide range of industries.
Who makes cabosil?
CAB-O-SIL® M-5 by Cabot Corporation – Additives – Adhesives & Sealants.
Is cabosil hydrophobic?
CAB-O-SIL TS-720 fumed silica is a medium surface area fumed silica which has been surface treated with polydimethylsiloxane (PDMS). This surface treatment results in a hydrophobic silica with a very different performance than untreated silica.
How do I store a cab O Sil?
Due to this, it is recommended that fumed silica be stored in a clean, dry area away from chemical vapors at ambient temperatures. Further, it is recommended that fumed silica packaged in paper bags be used within two years after manufacture date as bags may begin deteriorating beyond this time period.
Can you thicken gelcoat with cabosil?
You can either thicken the gelcoat with cabosil/aerosil or tint epoxy thickened with cabosil to get closer to the level you need then do a couple of finish coats of gelcoat.
Is cabosil hazardous?
Skin Contact: May cause mechanical irritation and skin drying. Avoid contact with skin. No cases of sensitization in humans have been reported. Inhalation: Dust may be irritating to respiratory tract.
Does fumed silica expire?
Further, it is recommended that fumed silica packaged in paper bags be used within two years after manufacture date as bags may begin deteriorating beyond this time period.
What can you add to epoxy to make it stronger?
Adding wood flour is a great way to thicken epoxy, allowing it to form a bead when joining two surfaces. Microbeads are great to add if you’re looking to create a sandable filler.
Can epoxy be used as a filler?
Epoxy Filler is a plastic filler that works on an epoxy resin basis and can be used as concrete and wood filler, as well as plastic filler and GRP filler. Its application is effortless, and the mixing of the two components is usually not difficult for the user.
Is fumed silica poisonous?
The general answer is “no”, fumed silica is not a dangerous material. Fumed silica is an non-toxic non-harmful material. It is not combustible nor explosive. In fact fumed silica has been applied in cosmetic, food and drugs for years.
What will thicken gelcoat?
Start with some white gelcoat filler and add some Cabosil, (a colloidal silica powder), to thicken up the mixture to around the consistency of peanut butter. This will allow you to use the substance as a filler and will keep it in place during the cure.
What can you use fumed silica for?
Like silica gel, it serves as a desiccant. It is used in cosmetics for its light-diffusing properties. It is used as a light abrasive, in products like toothpaste. Other uses include filler in silicone elastomer and viscosity adjustment in paints, coatings, printing inks, adhesives and unsaturated polyester resins.
Does adding more hardener to epoxy?
Adding more hardener will not make mixed epoxy cure faster because doing so changes the mix ratio, resulting in an improper cure. To make the epoxy cure faster, you can raise the ambient temperature using a heat lamp or space heater.
