Hydroxyl silicone oil) and the two kinds of polyethylene oxide hydrogen silicone monomer polymerization, between them after crosslinking hydroxyl end water loss and form of three-dimensional crosslinked structure of insoluble macromolecular will greatly improve the hydrophobicity, if you are considering to lower hydroxyl hydrogen silicone polarity hydrophilic part directly with metal catalyst, high crosslinking degree sufficient budget can be directly with platinum inorganic acid solution, the low degree of crosslinking soft film can use two lauric acid tin chloride or beryllium dilute sulphuric acid electrolyte, as appropriate, please reference. According to my understanding, it is only to improve the waterproof performance, and it is not necessary to use hydrogen-containing silicone oil to initiate polymerization. Isn't it easier to make o/w emulsion by adding sodium methylsilicate directly to hydroxy silicone oil?
