What are the physical properties of Gamma Glycidyl Ether Oxypropyl Trimethoxysilane
The physical properties of gamma-glycidyl ether oxypropyl trimethoxysilane are particularly important. At room temperature, this substance is a colorless to light yellow transparent liquid. It looks clear and has no cloudy appearance. Its smell is lighter, not pungent and intolerable, but it also has its own unique smell.
In terms of density, it is within a certain range. This value is very critical in the application of related processes, and it is related to the proportion of mixing with other substances. Its boiling point also has a specific value. When heated up to this point, the substance gradually changes from liquid to gaseous state. This property has far-reaching effects in operations such as distillation and separation.
Its solubility is also a significant physical property. Gamma-glycidyl ether oxypropyl trimethoxysilane is soluble in many organic solvents, such as alcohols, ketones, etc. This solubility provides the possibility for its application in different chemical systems, and can blend with a variety of organic components to exert its application. And its surface tension has certain characteristics. In the process of interfacial action and film formation, it affects the behavior of substances, making them interact with the interface in a specific way, or form a uniform film, or promote the bonding between substances.
Gamma Glycidyl Ether Oxypropyl Trimethoxysilane
Gamma - glycidyl ether oxypropyl trimethoxysilane, which is a kind of organosilicon compound. Its properties are both organic and inorganic, because it contains silicone and organic functional groups.
Looking at its physical properties, it is mostly a colorless, transparent to slightly yellow liquid at room temperature, with a slightly light odor. Its density is about 0.98-1.05g/cm ³, its boiling point is between 290-310 ° C, and its refractive index is 1.42-1.44.
Chemically, this substance is extremely active. Methoxy groups can be hydrolyzed, and silanol is formed in contact with water, which is then condensed and cross-linked to form a siloxane network structure. This property allows it to be used in the field of coatings and adhesives to enhance the bonding force between the substrate and the filler, and improve the bonding performance and durability of the product.
The glycidyl ether oxypropyl functional group has epoxy group activity. It can react with active hydrogen-containing compounds, such as amines and alcohols, to achieve chemical modification and cross-linking curing. In the preparation of composite materials, it reacts with resins to improve the mechanical properties and chemical corrosion resistance of the material.
In addition, due to its organic-inorganic hybrid structure, the compound also exhibits good weather resistance, water resistance and electrical insulation. In electronic packaging materials, it can effectively protect electronic components from external environmental erosion and ensure their stable operation.
Gamma Glycidyl Ether Oxypropyl Trimethoxysilane
Gamma-glycidyl ether oxypropyl trimethoxysilane, when using it, there are a number of things to pay attention to and must not be ignored.
First, this substance is reactive and prone to hydrolysis and condensation in contact with water. Therefore, when storing, be sure to ensure that it is in a dry environment, and the container must be tightly sealed to prevent moisture from invading. If exposed to humid air, it may cause premature reaction and affect its original properties.
Second, because it contains active groups, when mixed with different materials, its compatibility needs to be carefully considered. For example, when compounding with certain resins, it should be tested in advance to see if it is well compatible. If it is incompatible, it may cause the system to be stratified and the performance will be deteriorated.
Third, during operation, the substance may be irritating. The operator should wear appropriate protective equipment, such as gloves, goggles, etc., to avoid direct contact with the skin and eyes. If inadvertently contacted, it should be washed with a large amount of water immediately, and seek medical treatment according to the actual situation.
Fourth, environmental factors such as temperature and humidity are also affected during use. If the temperature is too high, or the reaction rate is too fast, it is difficult to control; if the humidity is too large, it is easy to cause hydrolysis side reactions. Therefore, it needs to be operated under suitable temperature and humidity conditions. Usually, the temperature should be maintained within a certain range, and the humidity should also be controlled.
Fifth, the proportion and dosage must be accurate. Too much or too little addition of this substance has a significant impact on the properties of the final product. Too much or excessive cross-linking of the system will increase brittleness; too little will not give full play to its modification effect. Therefore, the optimal dosage should be determined through experimental investigation.
Gamma Glycidyl Ether Oxypropyl Trimethoxysilane
Gamma - glycidyl ether oxypropyl trimethoxysilane, in the market, its price often fluctuates due to factors such as quality, manufacturer, purchase volume and market supply and demand.
Looking at the state of the market in the past, if it is ordinary industrial grade and the purchase volume is relatively considerable, the price per kilogram may be in the tens of yuan. However, if it is high purity and suitable for special high-end fields, the price is much higher, or hundreds of yuan per kilogram.
As in the world of "Tiangong Kaiwu", although there are no such precision chemical products, various materials also have different prices according to quality and source. Today's silane, with high quality, is expensive due to the complicated preparation process, excellent raw materials required, and high cost. For ordinary people, the process is slightly simpler, the cost is slightly lower, and the price is also close to the people.
If the purchase volume is large, the manufacturer has small profits but quick turnover, or there is a price discount. If the market supply is abundant and the competition is fierce, the price will tend to decline; on the contrary, the supply is tight and the demand is strong, the price will tend to rise. With its market price, it hovers roughly between tens of yuan and hundreds of yuan per kilogram.
