| silane coupling agent KH-590 | silane coupling agent KH-590 is the earliest widely used coupling agent and has a history of more than 40 years. One end of its structure has active groups that can react with epoxy, phenolic, polyester and other synthetic resin molecules, such as amino, vinyl, etc. The other end is the alkoxy group (such as methoxy, ethoxy, etc.) or chlorine atoms connected to silicon. These groups are hydrolyzed in the presence of water in aqueous solution or air to form glass, minerals, and inorganic fillers. The hydroxyl group on the surface reacts to form reactive silanol. Therefore, silane coupling agents are often used in silicate filled epoxy, phenolic, polyester resin and other systems. In addition, it can also be used in glass fiber reinforced plastic production to improve its mechanical strength and resistance to humid environment. The organic groups of the silane coupling agent are selective to the reaction of synthetic resins. Generally, these organic groups lack sufficient reactivity with synthetic resins such as polyethylene, polypropylene, and polystyrene, so the coupling effect is poor. In recent years, new varieties of silane coupling agents that have a good coupling effect on polyolefins have been developed, but limited to cost and other properties, the application is not widespread. |
| properties | silane coupling agent is also known as silane treatment agent; Primer. The general formula is Y (CH2)nSiX3 organosilicon monomer with more than two different reactive groups in the molecule. It can chemically bond with organic and inorganic materials (coupling) to increase the adhesion of the two materials. In the general formula, n is an integer of 0~3; X is a hydrolyzable group, such as chlorine, methoxy, ethoxy, acetoxy, etc., which is easy to hydrolyze to form silanol, which can react with inorganic substances and combine; Y is an organic functional group, such as vinyl, amino, epoxy, methacryloxy, mercapto, etc., which can react with organic substances and combine. |
| Use | Used in rubber, plastic, glass fiber, paint, adhesive, sealant and other products Used as glass fiber treatment agent and crosslinking agent It is a reactive and crosslinkable silane coupling agent that can be hydrolyzed under acidic or alkaline conditions and is widely used in natural and synthetic rubber, in addition, as a reinforcing agent and cross-linking accelerator, it can be used for composite materials (such as resin glass fiber composite materials), coatings, inks, glues and sealing materials, and can also be used as resin modification additives and enzyme fixatives. It is often used to treat inorganic fillers such as SiO2 and carbon black, and act as activator, coupling agent, cross-linking agent and reinforcing agent in rubber, silicone rubber and other polymers. 1. It has a sulfhydryl functional group, as a metal surface rust inhibitor has a special effect, used to treat gold, silver, copper and other metal surfaces can improve its corrosion resistance, oxidation resistance and improve its polymer The adhesive performance of the material. 2. It is widely used in filling polymer materials, and can be applied to thermosetting and thermoplastic polymer materials, such as epoxy, eye, phenosyl, polyvinyl chloride, polystyrene, polyinkstone, etc. 3. Especially in the rubber industry, the effect is particularly good, which can improve its mechanical properties, improve wear resistance, and reduce permanent deformation. It is suitable for NR, EPDM, SBR, polysulfide rubber, styrene-butadiene rubber, nitrile rubber, neoprene And polyurethane rubber, etc. 4. It is also suitable for a wide range of inorganic fillers, which can be used for glass fiber, silica, quartz powder, talc, mica, fly ash |
