MQ SILICONE RESIN

In the structure of MQ silicone resin, "M" stands for the monofunctional siloxane unit, which has the chemical formula R₃SiO₁₂. Here, the R group is typically an organic group like methyl. The monofunctional structure gives the M unit a crucial capping role. In the process of building the polymer chain, the M units act like buckles at both ends of a chain, effectively limiting the infinite extension of the chain and thus controlling the length of the entire polymer chain. Simultaneously, the organic nature of the R group imparts some properties of organic materials to the MQ silicone resin. Taking methyl as an example, it changes the surface energy of the silicone resin, significantly reducing the surface tension. In practical applications, this property has many positive impacts. For instance, in the coating industry, when MQ silicone resin is used as a coating additive, the lower surface tension allows it to spread better on the surface of the object being coated, much like water flowing evenly on a smooth glass surface, thereby enabling the coating to form a flatter, smoother, and more uniform film, greatly enhancing the quality and aesthetic appeal of the coating. Next, let's explore "Q". "Q" corresponds to the tetrafunctional siloxane unit, with the chemical structure SiO₄₂. The Q unit plays a core role in building the backbone of the MQ silicone resin. Its four active bonds, like the connection points of steel reinforcement in a building, cross-link with each other to construct a sturdy and stable polymer backbone structure. It is precisely because of this special structure that MQ silicone resin gains excellent rigidity and outstanding thermal stability. In high-temperature environments, such as in high-temperature protective coating applications for certain industrial equipment, MQ silicone resin, relying on the robust backbone built by the Q units, can withstand high-temperature scorching without deformation or decomposition. Even under prolonged high-temperature exposure, it can remain tightly adhered to the equipment surface, effectively protecting the equipment from damage caused by high temperatures, oxidation, and other factors, ensuring the normal operation and service life of the equipment. Furthermore, the proportional relationship between the M and Q units in MQ silicone resin, the M/Q ratio, acts as a crucial hub for performance regulation. When the M/Q ratio is high, it means that the proportion of M units in the overall structure is larger. At this point, the MQ silicone resin exhibits good flexibility, much like soft rubber, capable of bending and deforming to a certain extent without breaking. Its solubility is also enhanced, allowing it to mix and dissolve better with other organic materials. In the cosmetics field, this high M/Q ratio MQ silicone resin is widely applied. It can serve as a high-quality thickening agent, making the texture of cosmetics thicker and more suitable; simultaneously, it can act as a film-forming agent, forming a light, breathable, and smooth film on the skin surface. This not only enhances the cosmetic user experience but also provides a certain degree of protection to the skin, such as preventing excessive water loss from the skin.
8203 Methyl Silicone MQ Resin has enormous application potential in personal care.
Excellent film-forming properties. As a surface protective film, it eliminates the sticky feel of silicone oil, while improving water resistance, slipperiness/smoothness, scratch resistance, and increasing gloss. It achieves the same film-forming effect as DC1600 and 803
