Polymethylhydrosiloxane (Pmhs)

The Polymethylhydrosiloxane (PMHS) is nontoxic and insipid. As there are fair quantity of relatively active Si-H bonds in the molecule, under the action of catalysts it can react with chemicals containing active groups such as double bonds or hydroxyl groups. Due to two unique properties of methyl hydrogen silicone fluid including weatherability and hydrophobic characteristics, this product can be converted into film and used to produce a resilient waterproof coating on various materials by using metal salt catalyst at low temperature. Thus, it equips with outstanding water repellent property which prevents damage due to moisture, as well as mildew and rust development.
