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:

Dimethyl silicone oil can be applied to PET films, and it is quite common in practical applications. Its functions mainly focus on improving the surface properties of PET films, as follows:

When using dimethyl silicone oil to improve the hydrophobicity of PP matrix, viscosity is a key parameter. Its selection needs to consider the hydrophobic effect, compatibility with PP, processing technology and final performance requirements. The following are specific suggestions and analyses:

Dimethyl silicone oil has a significant effect on improving the hydrophobicity of polypropylene (PP) matrix, but its specific performance depends on the addition method, dosage and process conditions. The following is a detailed analysis from the aspects of mechanism of action, effect performance, influencing factors and application precautions:

The amount of amino silicone oil added in solvent-free resin systems is not fixed and mainly depends on the type of resin, target properties (such as smoothness, flexibility, surface tension adjustment), and the specific model of amino silicone oil (especially the amine value). The following is an analysis of reference ranges and influencing factors in common scenarios:

In the field of silicone materials, an organosilicon linear body (commonly referred to as a "linear silicone polymer" or "silicone linear body") refers to a silicone polymer with a linear chain structure. Its main chain consists of repeating silicon-oxygen bonds (-Si-O-Si-), with organic groups (such as methyl, ethyl, phenyl, etc.) attached to the silicon atoms. The molecular chain has no cross-linking or minimal branching, forming a straight-chain structure.

the viscosity difference of PDMS (polydimethylsiloxane, i.e., dimethyl silicone oil) is mainly caused by different degrees of polymerization, and it is also slightly affected by molecular structure (such as end group types). The detailed explanation from the perspective of chemical structure is as follows:
