In the application of color masterbatch, compared with other types of silicone oils (such as methylphenyl silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, etc.), the advantages and disadvantages of dimethyl silicone oil are mainly reflected in chemical properties, compatibility, functionality, cost and other aspects, as follows:

With its high-temperature resistance, efficient lubricity, environmental friendliness, and flexible formula design, methyl silicone oil emulsion is an ideal choice for die-casting release agents. In practical applications, it is recommended to select the appropriate model based on specific process parameters (such as temperature and material type), and optimize the dilution ratio and spraying method through small-scale tests to achieve the best release effect and cost-effectiveness.

Under appropriate conditions, Amino Silicone Oil can react with Epoxy Polyether through a ring-opening addition reaction to produce polyether-modified amino silicone oil, which combines flexibility and hydrophilicity. The detailed analysis is as follows:

Polydimethylsiloxane (PDMS) is a siloxane polymer with high chemical stability, which is difficult to remove by conventional cleaning. It is necessary to select targeted cleaning agents based on its hydrophobicity and chemical inertness, while strictly avoiding damage to the chip (silicon substrate, metal wiring, coating, etc.). Specific suggestions are as follows:

Both dimethyl silicone oil and vinyl silicone oil can be used as auxiliary materials (e.g., lubricants, plasticizers, damping regulators) in rubber shock absorbers. However, the two differ significantly in their applicable scenarios and performance. The selection should be based on the core requirements of the shock absorber (such as operating temperature, rubber material, damping stability, and service life). There is no absolute "better" option—only "more suitable" ones.

In the performance of amino silicone oil, the relationship between amine value and hand feel stiffness is not a simple linear correlation, but follows the rule of an "optimal range": Within a certain range, an increase in amine value can improve the hand feel; however, when the amine value is too high, the hand feel does tend to become stiffer, and the silkiness may also decrease. The specific principles are as follows:

Dimethyl silicone oil (with a viscosity of 200 cSt) can be used on glass surfaces, and its applicability mainly depends on specific usage scenarios and needs. Here is an explanation from the aspects of characteristics, applicable scenarios, and precautions:

Absolutely, and in polyester fabric coating, amino silicone oil is often a better choice, especially for meeting adhesion, hand feel, and functional requirements. Here is a detailed analysis:

Dimethyl silicone oil can be used for polyester fabric coating, but appropriate parameters need to be selected based on specific application scenarios (such as functional requirements, coating processes, etc.). Below is a detailed analysis and recommendation:
