Product Description

Description
Silway 732 water repellent is nontoxic and odorless. As there are 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.

Silway 732 water repellent can be converted into film and produce a resilient waterproof coating on various substrates by catalyst at low temperature. Therefore, Silway 732 water repellent has the outstanding property which prevents moisture, mildew and rust.

Besides, Silway 732 water repellent has a high permeability to water vapor, allowing the material to breathe.
 

Typical Applications

As a surface treatment in applications that utilize its ability to impart a water repellent surface and reduce water absorption  

For use on powders, glass, ceramic, leather, paper, metal, cement and marble
 

Key Features

Reduces water absorption into the substrate, thus reducing spalling due to freeze-thaw and efflorescence, thereby increasing the life of the substrate  

Non-toxic  

Produces a durable film after curing  

Curing time and curing temperature can be adjusted  

Effective concentration as low as 0.2%

Usage

Silway 732 is usually applied from dilute solution.  

Solutions are prepared by diluting Silway 732 with hydrocarbon solvents, acetone or methyl ethyl ketone, and stirring the mixture gently until uniform.  

The extent of dilution will depend on the surface to be treated and surface properties desired.  

Curing times are much shorter at higher curing temperatures.  

Catalysts are often used to accelerate cure.
