Methoxytriethyleneoxypropyltrimethoxysilane

Methoxytriethyleneoxypropyltrimethoxysilane can form covalent bonds with the polymer chains, creating a three-dimensional structure that is more resistant to degradation. Thus, it is frequently used as a crosslinking agent in polymers. Methoxytriethyleneoxypropyltrimethoxysilane provides the abilities of reducing friction between surfaces and resistance to adhesive. So, it can be used as a lubricant in many applications, allowing for smoother operation. In addition, it can reduce the surface tension of liquids and thus as a surfactant which allows liquids spread more easily. Moreover, methoxytriethyleneoxypropyltrimethoxysilane can act as a fuel additive to increase the combustion efficiency of fuels and improve fuel economy.


Common applications

APPLICATION IN LI-ION BATTERIES

In recent years, researchers are continually seeking the ways to improve the interface stability of electrodes and electrolytes under high pressure, because it is the key to successfully obtaining high energy density lithium-ion batteries. Lately, methoxytriethyleneoxypropyltrimethoxysilane was confirmed as a novel multifunctional electrolyte additive that can effectively stabilize the interface of both Ni-rich layered LiNi0.85Co0.1Mn0.05O2 (NCM851005) cathode and graphite anode in a full-cell by Pham and coworker [1]. This because methoxytriethyleneoxypropyltrimethoxysilane forms a stable and thin surface protective film on the NCM851005, containing Si species, which effectively reduced crack formation, metal-dissolution, and structural degradation of the cathode. And it also forms a stable solid electrolyte interface layer on the graphite anode, stabilizing graphite structure and preventing thickening of the solid electrolyte interface. The study proved that methoxytriethyleneoxypropyltrimethoxysilane had a potential to help the realization of high energy density Li-ion batteries through enabling wider working voltage range for Ni-rich oxide cathodes.


APPLICATION IN WATER-REPELLENT FILM

Lately, Nakamura et al., have successfully fabricated smooth, transparent, and hydrophilic pegylated organosilanes derived hybrid films by using a simple sol-gel reaction of PEGn-Si and tetraethoxysilane (PEGn-Si refers to CH3O-(C2H4O)n-C3H6-Si(OCH3)3, where n = 3, 6-9, 9-12. And when n is 3, the PEGn-Si is methoxytriethyleneoxypropyltrimethoxysilane) [2]. The organosilanes derived hybrid films showed excellent water sliding/removal properties. Although, the water sliding/removal properties of organosilanes hybrid film made by methoxytriethyleneoxypropyltrimethoxysilane are not as good as the films made by other two kinds of organosilanes, the methoxytriethyleneoxypropyltrimethoxysilane hybrid film still shows good performance. It is expected that this kind of water-removal surfaces will replace perfluorocarbon-based water-repellent surfaces, which will help reduce environmental damage.

Resin Bond Diamond

The resin bond diamond (RBD) is mutil-stalline diamond superhard abrasive specially produced for resin bond abrasives, which is composed of many subcrystals with embedded structure. In most cases, the resin binder system is phenolic resin or polyimide resin. In special cases, special resin binder and suitable additives may be used make the resin bond diamond more widely applicable. Resin bond diamond has irregular crystal shape, rough surface, excellent brittleness and excellent self-sharpening. Characteristics The excellent quality of high grinding efficiency, long life and high finish provides the best performance for resin bond abrasives, the details are as follows: Extremely high grinding efficiency and abrasive utilization : Under a certain grinding force, multicrystal particles are easy to fracture along the interface between subgrains. After the small abrasive subgrains are separated from the crystal particles, the new irregular shape subgrains form sharp edge angles on the cry...
