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.

 

 

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.
