1. It has good lubricity and is suitable for making high-grade cutting fluid. 2. It has lower surface tension and is suitable for antifogging agent. 3. Better softness and antistatic properties, suitable for fabric softener. 4. Good leveling property, suitable for adding a variety of resins (polyurethane resin, paint resin, plastic resin, etc.), which can improve the intermolecular stress of these resins, overcome the shortcomings of these resins, and obtain new properties. 5. It has good demulsification, and is suitable for oil-water separation in some specific occasions. 6. Application in other new fields. Compared with polydimethylsiloxane, the product can be miscible with water in any proportion, with polar organic solvents such as alcohol, DMF, ether, ester, etc., and partially or completely miscible with toluene, alkane and other non-polar solvents. It is very convenient to use.            When the product is used as leveling agent, the addition amount of the system is 0.1-1%, when it is used as softener, the content of the system is 1-5%, when it is used as cosmetic additive, the addition amount of the system is 2.5-5%, and other applications are determined by reference between 0.1-10% or by pioneer experiment.
