Methyl Hydrogen Silicone Fluid VE-202



CAS NO: 63148-57-2

Methyl Hydrogen Silicone Fluid VE-202 is a linear, hydrogen reactive polymethylhydrogensiloxane with a viscosity15-40mm²/s. Due to its chemical structure, VE-202 is a clear, odorless and colorless liquid.

VE-202 can be converted into film as it has relatively active Si-H bonds in the molecule, and can produce a resilient waterproof coating on various substrates by catalyst at low temperature. Therefore, Ve-202 has outstanding water repellent property which prevents damage from moisture, mildew and rust. Besides, its high vapor permeability allows the material to breath and let water, vapor escape outside without causing damages.

Key Features
