What is CAB-O-SIL used for?
Cab-O-Sil is used as a matting agent, thickener, and filler in many adhesives, sealants, plastics, waxes, inks, and coatings.
How do you store fumed silica?
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.
What is fumed alumina?
SpectrAl® fumed alumina products offer unique benefits because of their crystallinity and high purity. They feature particle morphology, hardness, thermal conductivity and optical properties that enable you to meet challenging performance requirements. In powder form, fumed alumina is fine, white and extremely fluffy.
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.
Is fumed silica edible?
* Do not eat, smoke, or drink where Silica, Amorphous (Fume) may be present since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet.
Is fumed silica poisonous?
Fumed silica is an non-toxic non-harmful material. In fact fumed silica has been applied in cosmetic, food and drugs for years. Due to its strong hygroscopicity(absorbing moisture), it may caused dry skin when directly contacted with skin.
Is fumed silica hydrophobic?
Fumed Silica – Hydrophilic and Hydrophobic With a unique range of both hydrophilic and hydrophobic grades available the number of applications are endless. Fumed (pyrogenci) silica is composed of synthetic silicon dioxide (SiO2) which is entirely amorphous, eliminating the risks posed by crystalline silica.
Is all fumed silica hydrophobic?
The hydrophilic nature of fumed silica is a result of the attachment of hydroxyl groups onto silica atoms just at the surface of the particle; the product is now capable of hydrogen bonding—this makes it dispersible in water.
What is cabosil?
Fumed Silica (aka Cabosil) is an extremely fine powder used to thicken virtually every liquid material. It is typically used to thicken resin, paint, dyes, and even water. Size. Choose an option. Quart.
