In the above structure, the silicone segment has 15 siloxane units, which are incompatible with the system and the surface tension is lower than the system; the polyether segment contains 8 hydrophilic EO units and 2 hydrophobic The PO unit is a hydrophilic segment because of the majority of hydrophilic monomers. It is used in water-based systems and is compatible with the system. Therefore, the polyether-modified silicone oil of the above structure can be used for water-based coating systems. Use leveling agent. In addition, since the siloxane segment in the above structure has a total of 15 units and has a sufficient length, the above polyether silicone oil can provide good smoothness and scratch resistance while providing leveling performance.
