3-Aminopropyltriethoxysilane Chemical Properties,Usage,Production

Silane coupling agent KH-550

3-Aminopropyltriethoxysilane is the earliest widely used coupling agent, so far has been more than 40 years of history. One end of the structure is provided with an active group, such as amino and vinyl, which can react with synthetic resin molecules such as epoxy, phenolic, polyester. The other end is alkoxy (such as methoxy, ethoxy etc.) or chlorine atoms which connected with silicon, and these groups. These groups can react with the hydroxyl groups on the surface of glass, minerals, inorganic fillers and generate reactive silicon alcohol in the presence of water in the aqueous solution or air. Therefore, silane coupling agent is often used in silicate-filled epoxy, phenolic, polyester resin and so on. In addition, it can also be used in the production of glass fiber reinforced plastic, in order to improve its mechanical strength and resistance to wet environment. The organic group of the silane coupling agent has selectivity to the reaction of the synthetic resin. Generally, these organic groups are insufficiently reactive with synthetic resins such as polyethylene, polypropylene, polystyrene and so on, so that the coupling effect is poor. In recent years, new types of silane coupling agents have been developed which have a good coupling effect on polyolefins, but it is not widely used in cost and other properties.
Silane coupling agent, also known as silane treatment agent, primer. The general formula is Y (CH2) nSiX3, it is an organic silicon monomer with two or more different reactive groups in the molecule, which can be chemically bonded (coupled) with organic and inorganic materials, and increase the bonding property of the two materials. In the general formula, N is an integer of 0 to 3; X is a hydrolyzable group, such as chlorine, methoxy, ethoxy, acetoxy and the like, and is easily hydrolyzed to form a silanol which can be combined with an inorganic substance; Y is an organic functional group, such as a vinyl group, an amino group, an epoxy group, a methacryloyloxy group, a mercapto group and the like, which can react with organic compounds and combine. The performance of typical silane coupling agent is as follows: For glass fiber, inorganic filler surface treatment. Used as a sealant, adhesive and paint thickener. It also can be used to the immobilized enzyme attached to the surface of glass substrate, to sand control in oil well drilling, to prevent sand from drilling, to brick surface with hydrophobic, to make the fluorescent lamp coating have high surface resistance, and to improve the moisture absorption properties of organic matter on the surface of glass in the medium of liquid chromatography. It is catalyst in the platinum by the chloroform and alkene with the active group  and then obtained by alcoholysis.

Uses

3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) is a versatile amino-functional coupling agent used over a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. The silicon-containing portion of the molecule provides strong bonding to substrates. The primary amine function reacts with a wide array of thermoset, thermoplastic, and elastomeric materials.
Silane coupling agent 3-Aminopropyltriethoxysilane is applied in plastic products (including cables, glassfiber-reinforcement plastics etc.), rubber products, adhesives, coatings, pigments dispersion, inks, magnetic materials (plastic magnet and rubber magnet), metallic casting resins and resins concrete, etc.
3-Aminopropyltriethoxysilane maximizes the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate, and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.
3-Aminopropyltriethoxysilane improves adhesion between magnetic powder and organic resins and dispersion of magnetic powder inorganic resins. Also these magnetic appliances attain higher magnetic orientation and excellent magnetic properties, higher mechanical strength, good processability, excellent weathering resistance.
In glass-reinforced thermoset plastics, 3-Aminopropyltriethoxysilane enhances the flexural, compressive, and interlaminar shear strengths before and after exposure to humidity. 3-Aminopropyltriethoxysilane greatly improves wet electrical properties.
With nitrile, polysulfide, expoxy, urethane, and adhesives and sealants, 3-Aminopropyltriethoxysilane improves pigment dispersion and maximizes adhesion to glass, aluminum, and steel.
When 3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) is used, glass-reinforced thermoplastics, polyamides, polyesters, and polycarbonates exhibit increased flexural and tensile strengths before and after wet exposure.
In glass fiber and mineral wool insulation, as a phenolics resin binder additive, 3-Aminopropyltriethoxysilane imparts moisture resistance and allows recovery after compression.
In shell molding foundry applications, 3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) strengthens the bond between the phenolics binder and foundry sand.
In grinding wheels, 3-Aminopropyltriethoxysilane promotes an improved, water-resistant bond between the abrasive grit and phenolics resin binder.
3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) is an excellent adhesion prompter in urethane, epoxy, and acrylic latex coatings, adhesives, and sealants.
