Description
Other Names: Methyl hydrogen silicone fluid; Methyl hydrogen silicone oil; Methyl hydrogen polysiloxane
Equivalent Brand: Wacker SILRES BS94
Cas No.: 63148-57-2
Chemical Structure:
Polymethyl Hydrogen Siloxane TPD-202 is nontoxic and insipid. As there are fair quantity of relatively active Si-H bonds inthemolecule, under the action of catalysts it can react with chemicals containing active groups, such as double bonds or hydroxyl groups.
Polymethyl Hydrogen Siloxane TPD-202 can be converted into film and used to produce a resilient waterproof coating on various materials by using metal salt catalyst at low temperature. It equips itself with outstanding water repellent property which prevents damage due to moisture, as well as mildew and rust development. Besides, its high vapor permeability allows the material to breathe and let water, vapor escape to the outside without causing damage.
