Specification:

The systematic name of Silica hydrate is dioxosilane. With the?CAS registry number 112926-00-8,?it is also named as Silica gel.?The product's categories are?UVCBs-inorganic; Fluka brand Silica, TLC Adsorbent; Silica TLC Adsorbent, with binder, no indicator; Bulk Adsorbents for TLC; Davisil Silica; Essential Chemicals; Silica Gels; Adsorbents (Inorganic); LPLC Separation Media; Davisil SilicaEssential Chemicals; Resins&LC Separation Media. It is?white to off-white powder?which is insoluble in water and inorganic acids, but soluble in?hydrofluoric acid and concentrated caustic soda solution. Additionally, Silica hydrate should be sealed in the container and placed in the cool and dry place.

Preparation of Silica hydrate: First,?salting the?sodium silicate solution and sodium chloride solution, and then using 31% hydrochloric acid to?decompose,?precipitating out particles of silica gel. After washing, dewatering, drying, crushing, screening, we can get the product.

Uses of Silica hydrate: It is not only used as adsorbent,?anti-blushing agent?and catalyst carrier, but also used as?gas chromatography reagent and?thin-layer chromatography reagent.?And this chemical is also used as?antisticking agent of polypropylene and?polyethylene film, thickener of?mastic coatings and unsaturated resin,?flatting agent of powder coating and?furniture coatings,?anticaking agent of?powdered material.

When you are using this chemical, please be cautious about it as the following:
It is not only harmful by inhalation, but also irritating to eyes, respiratory system and skin, so people?should not breathe dust and avoid contact with skin and eyes.?In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.?If you want to contact this product, you must wear suitable protective clothing and gloves.?In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)?Avoid exposure - obtain special instructions before use.

People can use the following data to convert to the molecule structure.?
1. SMILES:O=[Si]=O
2.?InChI:InChI=1/O2Si/c1-3-2
3.?InChIKey:VYPSYNLAJGMNEJ-UHFFFAOYAU

Storage Temperature: Store in a tightly closed container. Store in a dry area.
Usage:

Used to improve strength and durability of tires and other rubber products.
