Product Introduction

Description of 3-aminopropyltriethoxysilane :

Chemical Name:     3-aminopropyltriethoxysilane
Similar to:              
KBE-903 of Shin-Etsu, Sil-quest A-1100 of Mo-mentive,Xia-meter Z-6011 of Dow-Corning,
                                  Degussa AMEO,Ge-niosil GF93 of wacker,Dy-nasylan AMEO of Evonik

Molecular Formula:     H2N(CH2)3Si(OC2H5)3

CAS No.:  919-30-2
is a versatile amino-functional coupling agent may be an excellent candidate for use in a range of 
broad applications to provide superior bonds between inorganic substrates and organic polymers

Typical physical properties of 3-aminopropyltriethoxysilane 

Appearance:    colorless transparent liquid
Solubility:        Completely and immediately soluble in water (with reaction), 
                             alcohol, and aromatic and aliphatic hydrocarbons. 
                             Ketone are not recommended as diluents.

Refractive Index(n25D):      1.4200 +/- 0.0050 
Assay:                                  97%min. 98%min. 99%min. 99.5%min.
Potential Applications of 3-aminopropyltriethoxysilane : 
(1) Used in thermoplastic and thermosetting resin such as phenol aldehyde, polyester, epoxy, PBT, 
polyamide, carbonate, it can greatly improve dry and wet bending strength, compression strength, 
shear strength and other physical mechanical properties and wet electric properties, 
also improve the wetting property and dispersion of stuffing into polymer. 

(2) Used in the sand casting of resin, it can strengthen the adhesion, improve profile sand strength 
and antiwetting property. 

(3) added into phenol aldehyde in the production of glass fibre cotton and mineral cotton, it can 
improve moisture proof property and strengthen compression elastic resilience. 

(4) It is an excellent adhesion improver used in polyamide, epoxy, nitrile, phenol aldehyde adhesive 
and sealed material to improve the dispersion of pigment and the adhesion to glass, aluminum, 
iron, also applicable for latex coating such as polyamide, epoxy and acrylic acid type. 
(5) used to produce amino silicone oil and latex. 
Packing & storage of 3-aminopropyltriethoxysilane

1, painted Iron drum or plastic drum or IBC
     packing of 200kgs/drum,16000kgs/1x20'gp
     big packing of 1000kgs/IBC,20000kgs/1x20'gp
     Customized packing is ok.
     OEM is ok.

2, Sealed well, store in a cool, dry place. Avoid light.


Silanes are important to the development of high quality materials with enhanced functionality.
They are used in an incredible array of products that help to make living more comfortable and convenient.

No.1 Chemicals
1) Silanes are used effectively in adhesives,sealants and paints to improve adhesion to inorganic substrates.
2) Silanes are used to improve transparency and reduce viscosity during mixing and kneading.
3) Silanes are used to produce highly weatherable paints.

No.2 Automotive Applications
1) Silanes are used to make silica reinforced tires and in development of
    new materials.
2) Silanes are used to make high-molecular-weight rubbers and silicas.

No.3 Electrial Applications
