There are many types of silicone fluids, and they vary in their properties and areas of application. Some silicone oils are reactive, while others can cure. For example, methyl silicone oil can form a thin film or make a rubber-like solid substance on the surface of other objects, which can be cured by heating at high temperatures or using an appropriate catalyst such as peroxide. At the same time, there are silicone oils with epoxy groups in the side chain or end group of polydimethylsiloxane, which are called epoxy modified silicone oils, and this silicone oil can also be cured.
However, commercially available dimethicone fluids have been polymerized into low-molecular-weight dimethicone, which cannot be cured. Only under the action of peroxide or silane coupling agent, etc., can other silicone oils with free hydrogen equivalent continue to polymerize and become soft or hard and transparent solids.
The question of whether a silicone fluid is "reactive" or not usually depends on the type of silicone fluid and the specific application. For example, when handling fabrics, silicone oils are self-crosslinking, and this self-crosslinking oil also has good adsorption, which can make the fabric feel softer. This self-crosslinking can then be seen as a reactivity.
Silicone oil, as a silicone compound, has a wide range of properties and applications, both reactive properties and curing under specific conditions.
First of all, silicone oils exhibit reactive characteristics in certain situations. This is mainly reflected in the functional groups in the molecular structure of silicone oil, which are able to react chemically with other substances to change the properties of silicone oil or give it new functions. For example, certain groups in silicone oil can react with hydroxyl or amino groups on the surface of the fabric to form chemical bonds that improve the softness and slip feel of the fabric. This reactivity makes silicone fluids widely used in textiles, leather, coatings, etc.
Silicone fluids, on the other hand, can also be cured under certain conditions. Cured silicone oil is usually achieved through cross-linking reactions or polymerization reactions, which can cause a tighter structure between the silicone oil molecules, allowing it to change from a liquid state to a solid or semi-solid state. Cured silicone oil has excellent heat resistance, weather resistance and electrical properties, so it has been widely used in electronics, electrical, construction and other fields. For example, cured silicone fluids can be used as insulation for electrical equipment or as a building sealant.
However, it is important to point out that the reactivity and curing properties of silicone fluids do not exist in isolation, but are interrelated. In some cases, the reactivity of silicone fluids can facilitate its curing process, and cured silicone fluids may also exhibit new reactivity. Therefore, in practical applications, it is necessary to choose the right type and treatment method of silicone oil according to specific needs and conditions.
In summary, silicone fluids are both reactive and curable under certain conditions. These two properties make silicone fluids have a wide range of applications in many fields. Of course, the specific application and treatment of silicone oil also need to be selected and adjusted according to specific needs and conditions.
