What is the function of APTES?
(3-Aminopropyl)triethoxysilane (APTES) is an aminosilane frequently used in the process of silanization, the functionalization of surfaces with alkoxysilane molecules. It can also be used for covalent attaching of organic films to metal oxides such as silica and titania.
Is APTES a polymer?
Plasma polymerization of 3-aminopropyl-triethoxysilane (APTES) in microwave late afterglow was studied. First, sol-gel polymerized APTES was prepared and characterized by ATR–FTIR and XPS. The results obtained were used as a model to define the nature of nitrogen containing groups in the plasma polymer layers.
What is APTES silane?
(3-Aminopropyl)tiethoxysilane (APTES) is used as an amino-silane which is mainly used as a dispersant. APTES attaches an amino group to the functional silane for bio-conjugation.
Is APTES hydrophobic?
Plasma polymerisation of hexamethyldisiloxane (HMDSO) and (3-aminopropyl)triethoxysilane (APTES) was attempted to form a robust hydrophobic coating film on glass surface. Although HMDSO is a common precursor for generating hydrophobic surface, the HMDSO-polymerised thin film is poor in strength.
How do you store APTES?
You can store it in fridge at 4 degree centigrade. When you first open the bottle write a date on the container. If it is open for a long time then you have to check how much it is hydrolysed.
How do you store Aptms?
Is APTES soluble in water?
APTES-modified mesoporous silicas as the carriers for poorly water-soluble drug.
Does silane need to be refrigerated?
New silanes [Clearfil Silane Kit (Kuraray America); Versa-Link Porcelain Bonding System (Sultan Healthcare)] are stabilized and typically have a shelf life of two years. Keep these products refrigerated and remove them a few minutes before use.
Can you Silanize plastic?
Yes you can. Contact the silane manufacturers and they will prescribe the right silane.
How do you make 3 Aminopropyltriethoxysilane?
Prepare a 2% solution of 3-Aminopropyltriethoxysilane in acetone. For example, mix 1 part Amino-silane Reagent with 49 parts dry (i.e., water-free) acetone. Prepare a volume sufficient to immerse or cover the surface material. 3.
How to prepare 3-aminopropyltriethoxysilane reagent?
Prepare a 2% solution of 3-Aminopropyltriethoxysilane in acetone. For example, mix 1 part Amino-silane Reagent with 49 parts dry (i.e., water-free) acetone. Prepare a volume sufficient to immerse or cover the surface material. 3. Immerse surface in the diluted reagent for 30 seconds.
What is the molecular weight of 3-aminopropyltriethoxysilane?

What are the signs and symptoms of toxicity of 3-aminopropyltriethoxysilane?
Signs of toxicity included sluggishness, lacrimation, kyphosis, an unkempt appearance, piloerection, staining on the fur, closed eyelids, emaciation, and diarrhea. Survivors recovered at 2 to 9 days. [Organization for Economic Cooperation and Development; Screening Information Data Set for 3-Aminopropyltriethoxysilane
What is the hydrolysis half-life of (3-aminopropyl) triethoxysilane?
The hydrolysis half-life of (3-aminopropyl)triethoxysilane is 0.15 hours at pH 9 and 24.7 °C (1). (3-Aminopropyl)triethoxysilane is not expected to volatilize from dry soil surfaces (SRC) based upon a vapor pressure of 0.015 mm Hg (2).
