3-Aminopropyltriethoxysilane 919-30-2 KH-550/APTES 919-30-2

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.
